- hey I didn't notice that hehehe GREAT tagline I had thier! hehehe
-
- DW> Simplicity? On a 6-legged robot? I don't think it's possible. A
- DW> really crude 6-legger would need 6 motors to move the legs around one
- DW> axis (of course, I'm ignoring the two-motor variety, but that sort
- DW> of "walker" robot is pratically the same as a treaded robot) To make
- DW> a really neat robot, you're going to want to have the legs move with
- DW> two degrees of freedom, implying 12 motors. I suppose you could use
- DW> RC-type servo motors, but the thing is not going to be really strong
- DW> (unless you want to pay big bucks for the big servos).
-
- I've some super simple designs in email, but nothing that
- would be as capable as the "2 degree of freedom" design you
- suggest.
-
- DW> Somehow I think I'm going to get flamed... "what? I've got eight
- DW> 3" by 4" six-leggers munching on my ankles right now! All are powered
- DW> by watch batteries, and use a 4-bit processor! You're an idiot"
-
- Actually I'm not flameing you. However the designs suggested
- that though not nearly as versatile that it is possible to create
- a robot that can be controled with 6 legs and 2 motors. [like a
- track vehical] which is really all I needed. Though not fancy it
- should be suitable.
-
- DW> Seriously, a six-legger that had been stripped down to reduce it's
- DW> complexity seems like it would just not be that much fun to fiddle
- DW> with. On the other hand, I couldn't come up with any mechanism for a
- DW> six legger with each leg having two degrees of freedom that wouldn't
- DW> cost an arm and a ... leg? (uuupppphhh! pun not intended)
-
- perhaps the use of a peizo electric material in long strips to
- control "lift" with a spring to counter balance it and a another
- to control rotation. I know the japanese have a plastic material
- that acts this way but piezo materail has a very short "stroke"
