Heh i know that the title is going to raise some eyebrows! Actually their is a medical robot (for military use) being invented that (the current model at least) uses a Segway as a base. Its actually pretty nice and if anybody wants to forward this to Dean Kamen or Woody Flowers i think they would like it! Their design for a finished product looks pretty ambitious to me but i definitely hope they can do it. The only thing i see as a problem is that in allot of cases you DON'T want to move a person in case of spinal injuries, I guess that really doesn't matter if your in a shootout. Anyway this is a really cool use of a Segway and i was amazed it could compensate for that type of weight that high up!
