TEDx Talks: Amos Winter — The cheap all-terrain wheelchair

How do you build a wheelchair ready to blaze through mud and sand, all for under $200? MIT Mechanical Engineering Assistant Professor Amos Winter PhD '11 guides us through the mechanics of an all-terrain wheelchair that’s cheap and easy to build — for true accessibility — and gives us some lessons he learned along the road.

Amos Winter and his team at MIT built the Leveraged Freedom Chair, a cheap lever-powered wheelchair whose design and develop put the user first. It has won several awards recently, including MassChallenge and IDEAS/Global Challenge awards.
