Leveraged Freedom Chair
The Leveraged Freedom Chair (LFC) was developed through the MIT Mobility Lab, which Amos Winter created as a graduate student in 2007. The LFC is a mobility aid specifically designed for developing countries. It has a variable mechanical advantage lever drive train that enables its user to travel ten to 20 percent faster on tarmac than a conventional wheelchair. In this video, Amos Winter discusses the LFC and results of trials in East Africa. The team recently founded a non-profit, Global Research Innovation and Technology (GRIT), to manage the scale-up and distribution of the LFC.
