new IKA: possible to restrict movement of joints?


(hweihe) #1

Hello,

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! :stuck_out_tongue:

Hmm, thanks! :slight_smile:

I’m not sure if it will help me, but at least it is something new to think about… :-?
