Dave, you don't seriously think I was suggesting disabled people be perched up on a single wheel ?
I didn't mention it, but I was thinking a little outside the square - a multi-wheeled version for inherent stability, but taking advantage of :
- The ability to move sideways & diagonally
- Control via body (or maybe even just head) movements
I also have 2 wheelchair users in my family, & both of them thought that these attributes would be a wonderful improvement.
By "stalled technology", I was referring to the majority of powered wheelchairs still on the market - heavy units powered by a couple of ancient starter motors & lead-acid batteries ! It seems that modern brushless hub-motors & lithium batteries are only just starting to impact on wheelchair design, after having been around for electric bikes & model aircraft for quite a while.
Kind Regards,
Peter D.
