Blenders new IKA is making me problems: I am trying to model an industrial robot with inverse kinematics. Therefore I have set up an armature chain with 6 joints (the robot has 6 axis, you can see examples at http://www.kuka.de).
The inverse kinematic works so far that the chain follows the target-empty. But all the joints behave like ball joints, so the robot movements are mechanically impossible.
Is there a way to restrict the single joints to rotation in only one axis (like the old IKA had been by default)?
Thank you for any hints!
