Simon Burfield has built a prototype for the world’s first powered LEGO wheelchair using LEGO Mindstorms NXT. It uses Rotacaster wheels for multi-direction driving, and is powered by a total of 7 NXTs. I don’t fancy changing the batteries on that after a day out!

You can watch more video’s of Simon and his wife testing out the chair in operation on Youtube:

 

and Simon himself driving on an earlier prototype:
 

Well done Simon!
