Wheelchair for the developing world: cheap, rugged and easy to maintain


Core77's case-study of the MIT Mobility Lab's "Leveraged Freedom Chair" is a fascinating look at the difficulties presented by designing a sustainable wheelchair for use by disabled people in the developing world. The final product can be sold for $100 — a 90 percent reduction off traditional wheelchairs — and uses a lever-driven propulsion system that works better over rough terrain. It uses bicycle parts to keep costs down and simplify maintenance.
