Beginning in my junior year, I was chosen to work on the Wheelchair for Haiti team with three other engineers.  The goal of this project happened to be quite similar to my sophomore bike project, where there was a specific client which my team was designing for.  In this case, the boy was a young Haitian named Stephenson Gay, who at some point has lost the use of his legs.  Due to the extreme poverty of the family and the area where they live, he has never been professionally diagnosed.  He lives on the island of Île de la Gonâve which makes reaching him very difficult.  A co-advisor of the team, from the Geographic Science program, had a contact on the island that was able to reach the client on two occasions, but language and lack of any technology made it difficult for solid information to be gathered.  This entire project last four semesters and I am currently in the final semester.  The goal of the project began as designing a useful and cheap wheelchair that could be sent down to Stephenson, where he would use it to participate in village life and become mobile.  However, the team found out that sending anything to a foreign country using our budget would be considered sending state property to another country, which is illegal.  So with this new information our new goal was to develop a set of instructions that could easily lead a somewhat technical person to build the wheelchair, using minimal tools.  Our team developped a large number of concepts that would fufill the customer needs, and through various means narrowed down the list to only four concepts to be thoroughly modeled and tested.  By testing multiple concepts, our team will be able make verified decisions on which concept would best fufill the customer needs, or which sub-systems would work best.  My role on the team is the fabricator and computational modeller.  Due to my history with DIY projects and general tool usage, I was in charge of assembly of prototypes and developing fabrication means.  I am currently using Solidworks to test my computational models of our four concepts, one of which can be seen to the left.  By doing this, in addition to the mathematical modelling, our team should know exactly how the wheelchairs will react to a child using them.  A story done about our team by the school can be seen here.
