Mwisho Kwaheri – Final Goodbyes

12 08 2011

Ben and I went in for a few hours just to cut some materials, take some pictures with everybody, and for me to say my last goodbyes (as Ben will be here for another week). Everyone kept asking me when I would be back. It’s tough to say if I will even be back, but I would like to think I will return one day. They are used to Tish Scolnik returning many times as she had her January IAPs free, and I have volleyball. It was tough to say goodbye, and felt very weird walking out of Mobility Care for the last time.

The daladala ride home was a good sign though. As the bus approached, I saw that it was a Happy People Bus. There are many of them, but I had taken a photo during my first weekend of a daladala with a US flag and Tanzanian flag painted on the back. When we got out and the daladala drove by, I saw that it was the same bus! My favorite daladala and first time riding in it! I know its a very small experience in the scheme of things, but definitely made me a happy person!

Beth, Geoff, Ben, Daniel, Joseph and I went out for dinner to our favorite restaurant, the New Country Side Bar, which has the cheapest, meatiest, and tastiest food. We came back to the hotel and sat around for a while, listening to music and drinking my last Fanta Orange of the trip. I am still shocked that I will be getting on a plane in 16 hours, and be home in 46 hours!

I hope to write a couple more posts after this, reviewing or reflecting or something to wrap up my blog and adventure. I mainly wrote this blog to help me remember most of my experiences and some of the small things that happened. But I hope anyone who read my posts enjoyed them as much as I enjoyed writing them! (And I apologize for grammatical errors.)

Loose Ends

11 08 2011

The past two days have been fairly uneventful as I have been preparing to part ways with everyone that I have met here.

On Wednesday, Ben and I woke up early so that we could get our chair back from Zakeria, as well as receive some feedback from his two day experience with it.

The interview was complicated. We told him at the beginning of the interview to be brutally honest with us, as that was the only way to make the chair better if changes were needed. We continued to tell him this throughout, as we felt like we were getting responses that were too perfect, and that he was just telling us stuff to make us happy. Here is a summary of what we found out from him:

  • The chair needs to be a bit stronger at the caster wheel joint.
  • He didn’t have trouble instructing the daladala conductor on how to fold it, and it took 3 minutes to fold (the 3 minutes seems a bit iffy to me, but it could be true)
  • Friends who knew him when he gets off the daladala helped him put it back up. (Though he first said the conductor did it for him. I questioned this, as we were told the conductor wouldn’t do this from a third party one day. I asked the question again later on, and he changed his answer to friends helped him after the daladala dropped him off.)
  • They wanted to charge him more for it, so he paid 500TSH instead of 400, which isnt too bad. I never did ask him if he had it on his lap, or if it went on a seat. I am also suspicious that the conductor didn’t fold it all the way, as I had seen them do one other time.
  • It was difficult to take off the front wheel, something we knew before hand, and knew we needed to add a couple parts and grind down some parts for improved user-ability.
We took the chair from him in order to make the few improvements. But as we were hanging around the hotel later that day, Mateo came by to take the chair for Zakeria. I went out and talked to him about it, and he had been under the impression that he would be user testing it for 2 or 3 weeks. I told him that we would be making the minor adjustments and returning it to him for use after we left.
Today, Ben and I got up early again in order to go to Shop-Rite, where we picked up Hamburgers, buns, cheese, ketchup, mustard, and pickles. We got to the shop around 10:30 and began cooking the food. We were using a gas stove, but the matches were all gone and Agnes’ lighter was out. So in order to start the stove, Bert took his welder, welded on a scrap piece of metal, took the hot end of the welder and put it by the stove to light it!
Everyone loved the food, or at least they told us they did! It was fun to be able to give them a taste of American food, and they seemed to really enjoy it, especially the pickles and mustard, which they had never heard of before.
After lunch, I began working on the minor improvements. As I was cutting a small piece of metal the help guide the front leg in, the power shut off. It was disappointing, as it was my last day with power and I didn’t get anything done. (We had planned for hamburgers on Wednesday, but Lucas wasn’t going to be there.)
So we spent some time helping cut materials. After that, we assembled our chair and took a bunch of photos of it for our presentation we must give when we returned.
As I am heading out to dinner here shortly, I am sad to say that tomorrow is my last day here. But I am so thankful for all the great experiences I have had and have truly learned more than any other summer project could have brought me. I hope to post the photos from today later tonight, as soon as my camera charges.
Edit: I just remembered all of the recent local 2nd hand clothes I have seen:
  • It is 11-8 Cardinals over Cubs
  • 2 Blues hats
  • 3 Rams gear, one of which was a purple and green and yellow hat, weird
  • 2 SLU shirts, one worn by a daladala conductor in the bus I was in
  • An UMSL shirt
  • And all the Mizzou gear I mentioned earlier
  • Have failed to find MIT gear




48 Straight Hours of Research

9 08 2011

Ben and I have not stopped doing field research since 7:30 Monday morning. We met up with Zakeria, gave him our chair, and rode into Shanga with him. We had to take two daladalas in order to get to his work, but all the folding and transferring went smoothly…but then again Ben and I were the ones folding/unfolding. The good news though, the 5 times we’ve taken the chair onto the daladala with us we have not been charged any extra fees.

The chair rode straight and true for Zakeria as he rolled into work, and all of the workers gathered around us to watch our amazing folding chair. They were all excited to see it, and it felt good to see the mute and deaf’s happy expressions and we watched as they signed with each other. Before we left, I decided to ask Zakeria if he could fold the chair back up, as we would be leaving him and need to see how user friendly it was, and he would need to know how it worked for when he took the daladala home. It took him about five to ten minutes to do it, but he finally got everything where it needed to go. The backrest fold was definitely easier for him to do, as the caster wheel provides a lot of torque and is difficult to maneuver into its slot.

On Monday it was Nanenane day. Nane is 8 in Swahili (so August 8th, 8-8). It is a national holiday for farmers, and there was a huge festival in the Southeast area of Arusha. Ben and I had hoped to go, but we weren’t sure where it was exactly. So we went back to the hotel to figure it all out. As we passed by the local futbol field, I noticed there was a pickup game, the first one Ive seen since being here. Geoff had always planned on joining in on one of those games, so I thought to myself that it was too bad Geoff had gone to Dar es Salaam for the rest of his stay in Tanzania. But when I walked into the hotel, Geoff turned the corner! I immediately told him about the futbol game, and we got our shorts on and played for about an hour with 15 local guys. We approached the field and asked if we could join. They told Geoff to go one way, and me the other. It didn’t take long to realize I was surrounded by 8 opponents, and I only had one teammate around me. There were a couple other guys on my team, but were cherry picking on offense. So it ended up being 10 on 5, though the four guys on my team were clearly more skilled than the other team. It has been a long time since I’ve played soccer, and on straight dirt and rock, it was very difficult to control the ball. Needless to say, I made a pretty good fool of myself by losing control of the ball on a couple of breakaways. Finally, I was able to score a goal (on an unmanned foot wide goal, marked by a couple of stones). Geoff was also fortunate to score…shooting about five feet wide of the goal, deflecting off my inner calf, and rolling into the goal. It was one of the experiences here that was truly unique and I will always remember.

After showering, Geoff, Ben, and I took a taxi to meet Beth by the festival. We got 5 minutes out of the festival, when we ran into the heaviest traffic possible. So we ended up getting out and walking the rest of the way. The festival was pretty much an expo for a bunch of farmers to show off their products, as well as for developing farming techniques companies, and a zoo where we saw a bunch of cows, snakes, a baby hyena, pigs, and chickens.

The festival is three days long, beginning on Sunday. Daniel visited on Sunday, and had told Ben and I about the Arusha Technical College booth, where they had developed a motorized tricycle (something Daniel wanted us to work on if we had time). As good of an idea it is, an average chair costs $250. A motor cost around $500. So motorizing a wheelchair triples the price of the chair, and very few people can afford something like this. I talked with the guys who made it for a while, and asked if there was a differential in it for turning. They told me it did, but I couldn’t see one. Regardless, it was neat to see and to talk with the guys there.

Today, Ben and I went into the shop to find now power. It didn’t matter all that much, since we didn’t have much to do. We spent a few hours cutting material and riveting seat and backrests so they could be tied onto the chairs. Shortly after lunch, the power came on and I began working on a way to consistently drill a centered and  straight hole through angle iron. I found a way to do so, and successfully did it twice. I could have continued, but the large drill bit is a bit dull and catches on the material, and I can only endure so much semi-unsafe drilling.

We then took the backrest/armrest from our failed prototype here, cut it apart, and rebent the armrest to the 24.5cm radius. We then stuck one of them on the jig and made another successfully  folding armrest. We hope to use our two armrests (one which was made on friday) and put them onto the chair we made in Boston once we get it back from Zakeria.

Lastly, Ben and I discussed further steps. Ben suggested we email some of the wheelchair donors and see if they would give Mobility Care some funds in order to make 4 or 5 prototypes of the chair as well, to insure they could make the process repeatable on their own. In the next few days, I will make a neat instruction manuel in order to help them with the process of making the chair. It’s amazing to think that I will only have one day with power here. At the same time, I can’t wait to get home!





Treacherous Inclines and Hidden Waterfalls

7 08 2011

Not wanting to sit around the hotel for my last weekend here, Ben and I decided to take up the manager’s offer of a 6 hour hike, including a stop at a waterfall. We were unsure at first, but figured for ten bucks, even a mediocre hike would be worth the cost.

We were told that a guide would take us on the walk. When the guide, James, arrived, he told us that we would be joined by 8 students who were studying to become tour guides.

The hike began by walking up a pretty steep hill towards Mt. Meru. Ben and I quickly realized we were out of shape, but it wasn’t as tough as the challenge we would be facing later in the day. We got up to a foresty area, and it seemed as if we would just be walking through a typical woods the whole day. Nevertheless, the scenery was magnificent. But not long after that, we began a pretty deep descent. For some reason, I am very good at going up steep inclines…but awful at declining. Everyone in the group had to wait for me as I took my grand ole time. I felt so old.

When we got to the bottom, we found ourselves in a creek. We walked along the creek, passing a couple of mini water falls and jumping across the water numerous times, assisted by what seemed perfectly placed stepping stones. After about 20 minutes we finally approached a 130 m high waterfall. Ben climbed up to the highest possible point that you could get to. Knowing of my troubles getting down into the valley, I decided not to push my luck climbing on wet, slippery rocks in an area completely removed from any emergency access. The area the waterfall fell into was pretty much a cylinder, 220 m in circumference at the top. We spent a good amount of time by the waterfall until making our way back down the creek.

We ascended the valley on the opposite side we had come down. I have never walked up such a steep incline in my life, and having taken longer maneuvering around all the stones, I was a good distance behind Ben and the other half of the group. So I decided to climb as quickly as possible. I finally caught up to him, but was dead exhausted. Everyone’s legs were jelly by the time we got 75% of the way up. That last quarter of the ascent was brutal… but I guess that’s what I get from not having worked out for the past month.

After getting up, we took a long break to eat our lunch. We had an amazing view of the surrounding area and Mt. Meru (though the peak was cloud covered). After regaining some energy, we continued our hike. We soon came across scattered Massai homes, and continued to pass them during our descent.

Now this descent was quite steep, and I have a very difficult time walking down even simply sloped hills. But this was an hour descent down dusty and slippery paths. When I was younger, my family went skiing. Liz, my older sister, was not a fan of one particular slope and would cry out “The mountain is trying to kill me!” This memory came to mind as I did my best to get down.

The most amazing thing of the whole day though was the women and little boys, who would walk down the same paths, passing us, while carrying a bundle of firewood on their heads…barefoot. I understand they’ve been doing this their whole life, but still awe inspiring.

When we arrived back at the hotel, we just hung around the hotel, had a nice dinner, and passed out.

This morning we woke up and went to a Pentecostal Service. Last week, Ben went to this church’s English service (it was quite early and I failed to get up). So he wanted to experience the Swahili service. It began with an hour of praise and worship. Now, all of it was in Swahili, but it was amazing to see the entire Congregation dancing and singing along. The next two hours which followed were very confusing, especially because I did not know where the praise and worship ended and the mass began. I also have no idea of what the Pentecostal Religion is like, so I just sat and listened as best as I could. At the end of the praise and worship (I think), there were about 7 children around 11 years old who processed in, singing a song. They stood at the alter and sang for about ten minutes, then were joined with the rest of the children in the church, and then all processed out.

Once the singing was over, a few people gave some talks. (Probably where the service began). There were many times where the preacher would go to the alter and read a bible passage. Everyone in the congregation brought their own bibles and read along. There was another point where about 8 members of the congregation went up to the alter, kneeled before it, we all raised our arms out to them, and the preacher went on a ten minute shouting prayer, and two of the people kneeling began shaking and one eventually fell down. This was pretty powerful.

The last hour consisted of one man giving a homily. Near the end, he really got into it, got loud and emotional, and began chanting the same words over and over again, with the congregation repeating everything. After about fifteen minutes into this, while everyone in the church was exhausted from chanting, the preacher looked at Ben and I, asked if we spoke English, and told us to repeat after him, and continued to chant for about 1 minute in English. It was “I am washed in the blood of Christ”, (a few more, I am forgetting them right now though).

At the end of the service, all visitors where invited to the altar to introduce ourselves and explain why we were there. Everyone was very welcoming and many came up to shake our hands while up there. We were then walked out where we were given a couple of crackers and juice, and talked with some of the parish coordinators.

Afterwards, Ben and I went out for lunch, then walked around Massai market for some last minute shopping.

Tomorrow is nanne nanne, a national holiday for farmers. The way Daniel explained it sounded a lot like an events fair at college, where you can see all the groups and activities at the school, except for different businesses. It seems like it will be pretty cool, and since we dont have any work to do without power, we will probably attend. We are also trying to meet up with Zakeria to give him our chair.

As I enter my last week here, I wish I could stay longer, but at the same time I continue to get more excited to be able to get home. I hope I can make the most out of my time left here!

You can see the photos from my hike on facebook, linked under the photos tab.





Working Down to the Wire

6 08 2011

On Friday, Ben and I finally were able to be efficient in the workshop. Our plan was that he would work on the front wheel locking mechanism, while I worked on a jig prototype. I figured had there been two people working on the front wheel mechanism, then we would get in each other’s way, and things would move smoother.

It only took me about two hours to take my flattened out sheet metal, the tube we bent on Tuesday, and some other scrap parts, and create a successful jig for the folding armrest. I took my measurements and arranged the pipes accordingly. The armrest, when folding, barely even moved from its spot in the slot. It was a great success, and I was extremely pleased that the folding mechanism of our chair would be easily made and repeatable. And although I do realize they may never use this jig, I feel as if there is more of a chance now that a lot of guess work out of it.

After doing this, I went and assisted Ben in the manufacturing of the lock. A major component for this part was drilling two concentric holes in angle iron. Although I am not an expert in the shop, I have a lot more experience than Ben, so it was a good partitioning of skills, as Ben takes a little more time as he is building things to make sure its all organized. It took me a couple tries with some of the beaten up drill bits, but I got the holes to line up as close to the center of the angle iron as possible. I worked alongside Ben after that, doing any tasks that he needed accomplished to streamline our process, as Friday was our last day with power until Tuesday.

I watched as the time flew by on the clock, and as it reached 5:30, I knew we only had 30 minutes left. We were putting the finishing welds on the lock mechanism and adding the last part of the mechanism. We were done with all the power tools at 5:58. Power shut off at 6:05. Now that’s perfect timing at its best.

We brought back the chair to the hotel, hoping that Zakeria would be able to use it this weekend (after testing it at the shop…it was stable and strong!) Unfortunately, we were not able to meet up with him today, but we may be able to tomorrow.

But at this time, Ben and I are very pleased with how the chair turned out and how the jig works. We dont want to waste any more materials, but it would be intriguing to try and make another armrest, and then put it onto our prototype to see if we could get everything to match up like it should. The base of the chair is not difficult to make, so if we could make the top part easily, we have almost reached our full potential on the project.

 





Three Eye Opening Days

4 08 2011

Tuesday was another relaxed day without power. Ben and I got to the shop today hoping to brainstorm improvements for the chair. He was curious as to how they were able to bend the hand rims on the wheels 360 degrees. I walked him outside to show him the jig, which is a table which they lock to the ground, and the table had two circles, one 25 cm radius, the other 14 cm, with the small one on top of the short one. They put the pipe into the bender and walk it around till it creates a circle. I had tried doing this on the first day, but it didnt work. The hand rims are a smaller tube, so it is able to bend easily. The armrest needs to be larger to support the weight of the user as they transfer in and out of the chair. So when you try to bend the larger tube, it crumples when the stress gets too large. After ruining a large amount of steel the first day trying this, I had given up on it, trying to minimize the materials I used. But today we decided to try bending another tube by bending a little bit, shifting the tube, bending a little more, and continuing this until the whole pipe was bent (a little over 1/4 of a circle). We then checked it against the armrest we made in Boston with the hydraulic bender… it was a near perfect match and certainly would work!

We decided this would be the best size for the armrest, something we had concluded on in Boston, but wanted to test a larger size with someone here. Because we were wasting time trying to get that size work, we figure this one will do just fine. With that positive feedback, Ben and I continued to roll, as we improved on the locking mechanism for the armrest by putting a bushing through the armrest for the bolt to easily slide into. Ben also came up with an efficient way to tying a string to the bolt for a quick and easy release. After running out of things to think about, we went into town with Daniel to have our seat sewn together.

Ben and I were happy with the way the day ended up. We celebrated by ordering Chipsi Mayai, a french fry omelette. It was surprisingly tasty.

Yesterday, Ben and I fixed the seat to the wheelchair, put the wheels on, and began riding it around looking for problems. There was an immediate and apparent problem to the front wheel locking mechanism. The pipes were not bending, but they did begin to separate at the joint and a slight angle appeared (between the base and the front pipe). I spent some time thinking about the forces acting on the joint, and realized we needed to put a bolt in from the bottom to push the smaller pipe which runs through the inside upwards. Knowing the high torque put on the joint by the caster wheel, which is at a large distance and high force, and knowing the bolt would have to be added close to the joint, I wasnt too sure what would happen. What ended up happening was that the pipe was pushed down onto the bolt with such great force that it began to dent to pipe. This was bad. We tried troubleshooting it by adding another smaller pipe to reinforce it. It wasn’t great, but would do for now. Without much hope for the joint in the future, Ben and I decided to ask Daniel about Tish’s mechanism, as he knew more about it than we did. “Oh, its in the back if you want to see it!”… I guess I probably should have asked a bit earlier in my trip…

Ben and I checked it out, and man was it stable. It was ten times better than the mockup we had made in Boston. We rode the chair around, and realized it was much better than ours stability wise, though it takes much longer to take apart. So after some deliberation, Ben and I decided we would remake the bottom part of our chair, matching what Tish had made except for its folding aspect. Seeing her chair confirmed some of my suspicions that I had early on when making my prototype for the lock, but I had no time to investigate these suspicions. So, yet another lesson learned.

We took our chair back to the hotel with us to have Zakeria test it today. He rode it from our hotel to the main road. The street we are staying on is the worst road I have ever seen, and is a great off-road test for our chair. It seemed like the chair did pretty well, though near the end seemed to be veering to the right a bit. Once we got to the bus stand, Zakeria stood up on his crutches to watch us fold it, as he had yet explained it to him, and wanted to show him once before he did it. When we took off the front wheel, I immediately saw that the inside tube had separated from its welded position… I couldn’t let anyone sit in the chair for fear that they would get hurt. We helped pay for Zakeria’s motorcycle taxi ride because we felt bad for causing him trouble, and assured him we would make a better one for him to test.

So we ended up going to the shop to return the chair and solidify our plans for Friday when there is hopefully power. After we confirmed what we would do, I decided Ben would be able to build that part of the chair and I could work on the jig tomorrow. Before cutting some of the material I would need for the jig, I decided to confront Daniel about something that would have to be said eventually. I didn’t want to waste material building a jig if they were never going to use it, so I asked him about his thoughts on putting the chair into production. When I asked him this during the first week, he told me that yes, people would buy it. Today, he told me that they would try to make four or five chairs on their own and set them in the shop to see if people would want to spend the extra money on it (even though most of the money comes from donors). He told me that he would estimate raising the price from 420,000 TSH to 500,000 TSH ($53 increase). Im not sure about the cost of the materials that would be added on, but this seems close to reasonable, maybe a bit high. His answer was something I expected, but Ben did not. He did not like hearing this, and I too realized Daniel’s plan didn’t make sense logically.

I then began looking for scrap parts to make a prototype. I found some sheet metal that was twisted about in every other direction. Using the table clamp, I was able to straighten it out well enough for a prototype. I got all the parts I needed to make a rough go at the jig, and with luck there will be power and I will be able to work on that tomorrow.

I am pretty happy with were we are at. Though I know we could have been at this point after the second week, I realize all the times I have failed have helped me realize the wrong way to do it, and find the right way. So unfortunately I wont be able to build any attachments for the wheelchair, but I think by the time I leave next Saturday we will have our primary objectives fulfilled. It is hard to believe I only have 9 days left! Ben and I are going to try to make the most out of them!





Frustration leads to Simple Solution

1 08 2011

Not to be cliche or anything, but you know what they say about the best laid plans of mice and men. I had organized a solid plan of what work Ben and I would be doing today. We started out by fixing the right armrest of the chair so that it would not drag on the slot that it slides through. Unfortunately, we only made things worse. And every time after that, whenever we tried to make it better, the fold only got worse and worse. It was another morning full of walking away from the work to compose ourselves from the frustration.

Finally, I had enough and decided that we would just exchange the new locking mechanism I had designed for Tish’s folding mechanism for the front wheel on the prototype we made in M-Lab. After accomplishing this, we attached the brakes onto the chair, and began working on the mud guards, seat, and footrest. It was another long day, but by the end we finished everything that requires power. So tomorrow, we plan on putting the finishing touches for usability. We still need to paint it, but can always do that later.

After work I continued working out things in my head. I think the next step for us is to build a jig which will set up the armrest positions 100% correctly everytime. Though im not certain of which position that is yet, once the jig is built, I can spend a day researching this through trial and error (and having modeled it on Solidworks first as a headstart).

I continue to question the oder of my actions when I arrived here. I think that I should have started out by doing what I had done today, so that I could get back immediate feedback from a user. But the reason I went about things the way I did is to find out if I could repeat the manufacturing of the chair in the shop here. I know now that it is very difficult to do so, and may even be impossible. I don’t really believe it is impossible, but I do know that a jig is required to make the chair manufacturing repeatable.

When we made the chair in Boston, we had the use of a hydraulic bender, and we also bent a very large piece of steel. So when you measure from the pivot point to the armrest, the radius only changes by .5cm, whereas with the cold bender I used here, the radius changes by approximately 1.5cm, so it is very difficult to avoid contact between the armrest and slot which it slides through. Ben and I discussed the possibilities of different ways to bend the armrest while getting minimal kickback. We will continue thinking of the best way to do this in the next few days.

In addition, I have added some Solidwork photos on “Project Info” that I had from the last semester for a visual of the chair’s fold.





Kung Fu Safari

31 07 2011

Knowing there was no power at the shop, Ben and I slept in a little bit on Friday. We met up around 10 to discuss the tasks that needed to be replicated with precision for our chair, and how we were going to build the jigs to do so. This was a great discussion, and we feel confident that our jigs can be successful. We worked for about two hours on this, and then headed off to meet Sid, Ben’s pledge brother. We needed to meet up with him in order to pay for our safari we scheduled for Saturday. We ended up having lunch and dinner together, and Sid even stayed in our hotel in order to make the pickup for today easier.

 

The reason Sid is here is to work on a project he built during one of his classes this semester. What he created was a butter churner out of bicycle parts. When he began this project, he researched carefully about the needs and abilities of a local Massai village. Everyone he talked to here in Arusha said the village owned bicycles, could waste some of their milk, and that there was a market for butter. The first day he arrived here, he found out that all three of these facts were wrong, making his project completely null. He has spent the last six weeks researching needs of the village and learning about their lifestyle so that other students could solve some of their problems.

 

So yesterday, after getting all of our business done, we were bored and decided that we would go try to find a movie theater. We took a daladala to the Cinema were we hung around till the movie began. This area was an extremely muzungu place, and I felt like we were in a courtyard of somewhere in the Southwest US. We saw Kung Fu Panda 2. It was relaxing to separate ourselves for a bit from feeling like we were in Africa. Was it something that pampered American guys might do? Yes. But was it worth it? Totally!

 

We got up this morning at 5:30 to begin our Safari. The three of us went, along with Rob. I may have mentioned him before in little detail. Rob, and his wife Barbara, are in the Volunteer Service Association (the New Zealand Peace Corp). The were in Arusha 22 years ago working on an agriculture, and are taking a vacation to reconnect with lost friends, as they had lived here for two and a half years. They are working on the beginning stages of opening an orphanage for an area thirty minutes outside of Arusha.

 

The safari was a simple, one day trip to Ngorongoro Crater. I believe it is the largest crater in the world, and a simply amazing area. I hope to post pictures soon. We saw zebra, ostrich, buffalo, gazelle, two lioness’, hippos, and elephants. From a far distance, and on binoculars, we caught sight of a couple rare black rhinos. The driver assumed we would see them again, so didn’t drive to that area where they were (what I believe to be the biggest mistake of the day). But its tough to complain after the amazing day we had, and after the best meal of chicken, orange slices, bananas, hardboiled eggs, rice, cornbread cake, and some really good bread. I almost got injured during lunch, as I was walking around eating my chicken. I was enjoying the scenery, when the guide yelled at me to get down on the ground. I was confused, and it took a while, but finally I got on the ground. What had happened was that a red kite, a type of eagle, had begun to dive towards my chicken/hand to grab it. Apparently they are known to do this, so you must eat your food sitting down so that they don’t have an angle of attack in which the can continue their flight in one nice swoop. Many times people resist the grabbing of their food, so the red kites have become used to attacking both the hand and the food. I probably wouldn’t have given up my chicken without a fight…and I would have lost.

 

I plan on spending my day tomorrow working on the design of the jigs, and preparing a list of what needs to be done and in what order to streamline our project. I have learned from 2.007 (Design and Manufacturing I) that I work much better in the shop if I have a step by step guide for what I need to do when I get to the shop. So Ill write one of those up tomorrow, and probably walk around town for a bit as well. It should be an interesting week, and hopefully we will have user testing begin on Tuesday!

 

Its 9-6 Cardinals. Also, I have seen a St. Louis Blues Cap, a St. Louis Rams polo shirt, a Mizzou shirt (a while ago), a SLU Health Care shirt, and even at one stand, 6 or 7 new winter beanies with the Mizzou Tiger on it.





I Only Have How Many Days Left?

28 07 2011

Knowing that my time is dwindling here, and knowing that with the power situation here, I may only have 5 days left where there is power at the shop… thats not a lot. So while still enjoying my time, I have begun to stress a little and really worry about not finishing everything I had planned to accomplish while here. Today didn’t help either.

When Ben and I met up with Daniel this morning, he told us there was no power at the shop. We decided to go in anyway and see what we could do. Halfway there, Daniel received a phone call telling him the power had turned on! We were excited, as we only had to put some finishing welds on the upper half of the chair… little did we know this would be a day long adventure.

When we got to the shop, we began by putting the brakes and quick release for the wheels on the chair. This took about an hour, but we knew we had plenty of time left in the day, so Hakuna Matata.

The chair folded nicely while tap welded, with a bit of contact with the slot which the armrests slide down, but nothing to really worry about. After putting the finish welds on, it took a great amount of force to fold, and we knew we had to cut and paste to make it work. We took the backrest and armrests off the hinges, and I soon realized many of the parts were off their mark, and that we had quite a heavy task in front of us. I will not go through all the things we had to fix, but we continued to run into problems. Not feeling too well (similar to last time I was sick), I became very frustrated with the chair a couple times and had to walk away from the work. I have never felt so defeated while working on that chair than today. Finally, after Ben and I endured hours of doing our best to weld and grind the parts to fit together properly without having to pre-load any of them, we finally finished with an acceptable chair. We noticed there was a tiny bit of contact with the right armrest that, at one point of the fold, caused some difficulty. We knew this would be an easy fix, but right before we began on that, the power shut off  (at 5:35, and the power usually shuts off at 6, so I didn’t mind too much.)

Ben and I are glad to know we are close to finishing the chair. We are excited to design and build the jigs for our wheelchair, so that all the guys at Mobility Care have to do is build the parts in our jigs, and there wont be any problems while putting it together. We know tomorrow is a no power day, and Daniel will be traveling to Moshi. I plan on staying in the hotel and working on designing the jigs, so that they are easy to build when it comes time to do so.

We are also working on setting up a Safari to Ngorongoro Crater! His pledge brother is in the area working on a project of his own, and leaves on Tuesday, so we are trying to have an awesome weekend!

I have also put up the links on the photos page for my third week here, and the Massai Village adventure (minus the gory photos). Enjoy!





Research in Africa

27 07 2011

Like I said yesterday in my post, on Monday Ben and I travelled to Usa River Rehabilitation School where we met with a professor and five students.

When we arrived at the school, I quickly noticed that everyone there had some sort of physical disability. We were walking behind this woman who had ducked feet. I’ve seen people who have a slight angle to their feet. This woman’s feet were at a 90 degree angle, with her toes pointing towards each other. She had some difficulty walking, but for the most part was able to move well on the paved sidewalk.

Daniel walked us over to a table where there was a man who was wearing a dress shirt and sweater vest. (Sweater vests are very popular here, and I am tempted to buy one.) We introduced ourselves, and he introduced himself as Gabriel, a faculty member at the school. He was a medical practitioner and physical therapist at the school, and began working there about ten years ago. He gave us an overview of the school and its purpose. The school was started in 1988 for the disabled in the range of 16-35 years old. The students go to the school for three years, where they learn English, and then either tailoring, shoe making, or carpentry. After their three years, the school helps the graduate find work or begin their own small businesses. It cost 650,000 TSH per year (so $430/year).

Talking to Gabriel was very insightful, but somewhat discouraging about the disabled communities situation. He pretty much told us that when they are young, they are neglected at home because taking care of a disabled child is very expensive. Very rarely do they get to go to school, and so then when trying to find work, they are usually left to fend for themselves. The school has been trying for the last 20 years to get the government here to aid in disabled assistance, including increased handicapped accessible areas of town. The government has just ignored their pleas. He also talked briefly about how difficult it is for wheelchair users to take daladalas.

We then asked to talk to a few students at the school. Since we decided to go to the school at the last minute, we had not prepared as well as we should have, so when 5 students wheeled in together, it was a bit overwhelming. We started off trying to get to know them. There was Erasto, Delphian, Nishaki, Agnes, and Cathbert. All of the students were at school for tailoring, besides Cathbert, who was studying shoemaking. Daniel translated for us, as none of them knew any English.

Erasto is a twenty year old man who got his first wheelchair in 2008, shortly after being paralyzed in a car accident. I had suspected this, as he was in very good shape and had pretty good posture. He also talked up the most, and at the end of talking with them asked him if he would test our wheelchair.

Delphian is around 18 and used crutches until 2009 when she was given a wheelchair. Nishaki who is also around 18, began using a wheelchair after she was in a car accident as well. They talked the least, and mainly giggled at how we talked and the questions we asked.

Agnes is in her thirties, and has been in a wheelchair since 2003. Before getting her chair, she crawled everywhere, including school when she was younger. She would crawl to school, about 2 or 3 km. I immediately felt bad about all the little complaints in my life, such as slow internet, not enough peanut butter on a sandwich, and not enough leg room on a 3 hour flight. She was the only one of the five without a chair that was built by Daniel’s shop. When the buses continued to reject her wheelchair, she had to return it in exchange of a donated chair from the US, which folded like a hospital chair. She didn’t like this chair as much, as it had two castor wheels, so did not work well off of paved sidewalks.

Cathbert is around 16, and began using a wheelchair last year. Prior to his chair, he crawled around, but never went to school. After our questions, we asked them if they had any questions for us, unrelated to wheelchairs. Cathbert was the only one who spoke up, asking us if there was anybody who made shoes like he did in America. We told him no, and that there are people who make the machines which then make shoes. He seemed delighted by the answer, though a bit confused. (Im not too sure about how our shoes are made, but didn’t want to say that people in china make our shoes…)

When telling them about our project, they seemed enthusiastic about our chair. Though they do not have to worry about it as much right now, as they live at the school, they will eventually need to take the daladalas on a more regular basis. Currently, they take a bus home for their breaks twice a year. They said that taking their chairs with them are a pain and expensive, costing 3,000 TSH, plus the 2500 for themselves.

We also asked them what could be improved on the chair, hoping to come back with another project for M-Lab next year. They only stated simple things, such as a way to have an umbrella attachment, a basket, and drawers on their chair for storage. Erasto also told us that even with the cushion Mobility Care provides, the seat is uncomfortable, and creates pressure sores. (Pressure sores are very serious. Because a person may not be able to feel the area of their body on the seat, they do not shift around the way we do when we become uncomfortable. This discomfort is caused by pressure on the seated area, and will soon turn into sores if they do not shift around. These sores can become very infected and dangerous for the person.) I know there is a lot of research in this area of wheelchairs, and there are probably some very expensive solutions, but definitely something to look into.

The interview was enlightening, and helped us clear up some doubt in our project. It was nice to get the student’s view of their chairs before they got out into the real world and focused solely on transportation. We knew that we would have more interviews with people who work, and could get a different view of their chairs.

(I already wrote a post for Tuesday)

Ben and I woke up this morning figuring we wouldn’t have power, but satisfied in the amount of work we got done yesterday. I had a goal set for today to visit the steel shop where Mobility Care buys their steel from, and then begin designing the jigs on Solidworks (a Computer aided design program).

To make part of the chair, I had to take a 6×6 cm rectangular bar, cut, and reweld to dimensions of 6×3.5cm. This is not the most fun process, as it is tough to cut perfectly straight pieces. So I wanted to see if the guys at the shop could bypass this laborious task. They had a 6×4 cm extruded bar at the steel shop, which I think will do for its purpose on the chair, and may even provide some extra benefits.

After the long walk to the store, I knew that we were only a short daladala ride away from Shanga, the glass bead making shop that I had visited during my first weekend in Arusha. I knew that they employed the deaf, mute, and physically disabled to work there, and had seen several wheelchairs around the shop. I knew this would be a good opportunity to talk with wheelchair users in the work force.

After getting shown around the shop again, we started our interviews off by talking with Mr. Beads. I suspected that talking with him wouldn’t be too helpful, as I had correctly guessed that he rarely used his wheelchair. Unless he was travelling long distances away from daladala stops, he crutches everywhere, and never needs to take his chair onto a bus. Instead of dismissing him, we just tried to get as much information from him as possible. And we were super glad we did talk with him. William has been a bead designer ever since he was little when his mother taught him how to make beaded jewelry. He used to work in his home, and people would come to him and make requests for jewelry. He did this until three years ago, when he began working for Shanga. When we asked him what his biggest concern was, he told us that there needs to be a way where the disabled can get aid to start their businesses. He told us the steps necessary to do this:

-       Find someone interested in helping start a business

-       Bring three or four disabled people together to work as a group

-       Make sure at least one of the group know the business that they intend to go into well

-       The person who knows what he/she is doing goes around, picks out materials needed to start the business, and take that list to the donor

-       Start building some of the pieces/parts/whatever they are making

-       Begin marketing

-       Sell their product, and use that money to continue their work

Mr. Beads is very passionate about this, and has helped many disabled people he know get work (and Mr. Beads knows pretty much everyone in Arusha). In addition, he gave us the names of two companies in Dar es Salaam that do similar work with the disabled as Shanga. I plan on looking these up later, but they are Wonder’s Welders and Daggie (?)Tricycles.

After talking with Mr. Beads, we talked with another man, Zakaria. Zakaria tested the wheelchair that Tish made, and so we were hoping he would agree to testing ours as well. He has worked for Shanga for three years now, mainly taking small, flat pieces of colored glass and decorating candle holders, lanterns, and mirrors. Some of his work is very cool, as we got to see him working as we walked around the shop. We asked him what he did before Shanga, and he told us he was in between jobs. He had previously been a welder for the Money Maker Pump, an MIT project from about 15 years ago that allows small farms irrigate their crops. (Some good info here: http://kickstart.org/tech/technologies/micro-irrigation.html

He only had to search for 3 months to find a job at Shanga. We asked him about the availability of jobs to the disabled, and told us that most employers in Arusha are Indian and do not employ the disabled. He told us more American and European employers are more willing to hire them, but many times the disabled workers have very little experience and even less education.

I was surprised that he worked as a welder prior to working at Shanga, so I figured he had gone to school. In fact, he did go to Primary school, and then went to Usa River rehabilitation school where he learned how to weld and make the hand tricycle wheelchair that he uses. This wheelchair is a three-wheeler with a hand pedal that drives the front wheel. He takes it to work everyday, which takes about 40 minutes. I asked him, if he had a wheelchair that he could take onto the daladala for no extra charge, would he prefer this? He said yes, but only if it the conductor did not charge any extra. I am not sure if he was saying this just to please Ben and I. He was willing to have the chair we make for a few days, where he has multiple tries at taking the chair on the daladala with him and can get a feel for its everyday use.

The only thing that he would like to see improved on his tricycle is a motor powered chair. Last summer, some guys went to Kenya to test a motor powered chair. They said it was very dangerous and doubled the cost of the chair. I do know that Mario, our class instructor, designed a cool gear system where going one way on the pedals drove the chair in a low gear, and the opposite direction, a high gear. This would help solve the problem of going uphill.

Finally, we talked to a woman named Mary. She has worked at Shanga making jewelry for a year and a half. Like Mr. Beads, she worked at home making beads before finding a job at Shanga. She explained that it is very difficult to run a business that way, as it is hard to get the materials needed for the jewelry.

Mary has been in a wheelchair since 1992 due to a spinal chord injury. She went to primary school for a while, but it became too difficult, and couldn’t go to secondary school. Her only complaint about the chair was that she wanted it to fold like a hospital chair. We explained to her this would not be do able with a three wheeler, as it would ruin the purpose of its stability and strength. Ben and I don’t think she understood, and we felt as if she was just trying to tell us what we wanted to hear. It may have been this way because she spoke English pretty well, but we don’t know.

Of the 9 locals we talked to, only Gabriel, Mr. Beads, and Mary knew English. It was really the first time I have ever needed a translator for a long conversation, and it was quite the experience. Ben and I got a lot of good feedback, and feel very confident that a folding wheelchair can make a big impact of a disabled person’s life.

We are hoping for power tomorrow, but if we do not get it, then I will spend most of the day designing jigs, so that we can be as efficient as possible when building
