Re: [CAD_CAM_EDM_DRO] parallel kinematic machine run from Mach

Hi Graham,

Nice action! I wouldn't have thought of it. Must be a pain to do IK
for it, 'tho.

I'm doing some robots, a R/C powered hexapod (not CNC) robot, and a
biped of my own design. I made all the parts I could, of course!
Shelob (giant spider from Lord of the Rings) hexapod has 18DOF (IK
needed), 3 per leg. Plans are to add to additional legs to make her a
real spider. Insects of course have only 6.

biped uses 4 servos, and walks with an exaggerated "foot lift" to clear
the other foot.
