MIT - Wheelchair Design for Developing Countries
Members: Alice Brooks, Xuefeng Chen, Sarah Cooper-Davis, Harry O’Hanley, Levi Schmidt
Lab instructors: Gwyn Jones, Mario Bollini
Class Instructor: Amos Winter
Our mission is to design and build a tricycle attachment. The attachment is to be affordable, and locally produced, and easy to use on the terrain of a developing country.
The functional requirements placed on wheelchairs in developing nations are vastly different then those on wheelchairs in nations like the US. The users must be able to cover long distances on very poor paths as well as navigate tight indoor spaces. Currently there are decent solutions to either problem, with the difficulty being combining them.
A tricycle attachment for standard 4-wheel wheelchairs gives the owner the advantages of a standard wheelchair in tight spaces, but allows them the freedom of a tricycle after only a few movements.
