3RD World Wheelchair

February 18, 2010 By Kristeen

Amos Winter, a MIT graduate student, has developed an innovative mobility aid specifically for developing countries. Conventional wheelchairs are nearly impossible to propel on the sandy roads and muddy walking paths frequently encountered in the developing world. The Leveraged Freedom Chair (LFC) uses an innovative approach to solve this problem by assembling this wheelchair from available bicycle parts.

The LFC has a variable mechanical advantage lever drivetrain that enables its user to travel faster on tarmac and off road like no other mobility aid available. Human upper body force and power outputs were used to optimize the drivetrain geometry for optimal performance on a wide range of terrains. The LFC can easily be repaired anywhere in the 3rd world and costs less than $200 to build.

I love this idea. Lots of innovator think that developed countries are the only ones with needs, or maybe the only ones who can pay to satisfy their needs. I think there is a huge opportunity in third world countries.
