Im currently making a robot project (yeah we all start somewere) and im stuck on the rigging of the legs, so far ive tried using 3 bones to do the job but it just doesnt work right. heres some pictures..
I hope this explains my idea clear enough?
My main problem is I want to lock off bone 3 to just rotate on z-axis and have the other two bones (1,2) translate x,y to reach my foot null. At the minute no matter what I try (including upvectors) all 3 bones will bank/roll to reach the foot null.
Effectively im trying to copy the rear end of a JCB tractor exactly motion wise.
