IntelliWheels: The Continuously Variable Transmission for Manually-propelled Wheelchairs
University of Illinois - Urbana-Champaign, 2010 - $20,000
This E-Team is developing IntelliWheels, an after-market addition to off-the-shelf wheelchairs that significantly decreases the effort it takes to propel manual wheelchairs. IntelliWheels uses a gear shifting system to make pushing a wheelchair easier: the user moves forward, backward, and turns by pushing on the hand rims on either side like normal, but two automatic transmissions continuously change gears to keep the user operating in the most efficient way possible. This happens automatically, without the user thinking about it or needing to do anything.
The team built one prototype already, but it did not perform well. The team is now looking to build on what was learned from the first prototype and continue the development of IntelliWheels into a viable product and business focused on the US market.
- The team has since incorporated as Intelliwheels
