Very cool Omniwheelchair

with one comment

Simon Burfield, a.k.a. Burf has made a super cool model.  By model I mean chair and by chair I mean omnidirectional wheelchair. Oh and it’s life-sized, too.  Yeah, it is capable of handling no less than 90 kg!  I saw a video of an early prototype a few weeks ago but this new one is even better-er!

Some facts:

  • It uses 7 Mindstorms bricks. One for controlling and 6 that are used for moving.
  • Each driving NXT has two motors attached to it.  I presume that a third motor would probably be pushing it when it comes to providing current.  It’s not easy to push that much LEGO and human meat around.
  • The master NXT has 4 touch sensors connected (forward, back, left and right) and 2 motors to switch on the drive touch sensors.
  • It uses Rotacaster’s omniwheels to make it possible to move in any direction (except up, of course).
  • It is programmed in ROBOTC (of course)

Here’s one of the videos he made:
