I have modeled a toy robot and have given him a basic armature. I’m am now trying to make it easier to animate. I have never done a robot and I’m wondering if you use ik controls for legs and arms like these where the parts don’t deform or go into each other on when they bend. I have tried an ik constraint for the leg but when I pull it up the small area for the knee to rotate starts bending. So any guidance would be greatly appreciated.
