MIT wheelchair steers clear with Wi-Fi

A group at the Massachusetts Institute of Technology has invented a wheelchair with all the self-navigating abilities of a GPS device.

Only instead of being inhibited by the need for a satellite signal like a GPS device, MIT said Friday, the location-aware wheelchair uses Wi-Fi and can work indoors.

Just like with a GPS navigator, the wheelchair has programmed favorites. Better yet, it works by voice recognition so you don't have to type in a request.
