- Simplicity? On a 6-legged robot? I don't think it's possible. A
- really crude 6-legger would need 6 motors to move the legs around one
- axis (of course, I'm ignoring the two-motor variety, but that sort
- of "walker" robot is pratically the same as a treaded robot) To make
- a really neat robot, you're going to want to have the legs move with
- two degrees of freedom, implying 12 motors. I suppose you could use
- RC-type servo motors, but the thing is not going to be really strong
- (unless you want to pay big bucks for the big servos).
-
- Somehow I think I'm going to get flamed... "what? I've got eight
- 3" by 4" six-leggers munching on my ankles right now! All are powered
- by watch batteries, and use a 4-bit processor! You're an idiot"
-
- Seriously, a six-legger that had been stripped down to reduce it's
- complexity seems like it would just not be that much fun to fiddle with.
- On the other hand, I couldn't come up with any mechanism for a six
- legger with each leg having two degrees of freedom that wouldn't cost
- an arm and a ... leg? (uuupppphhh! pun not intended)
