I checked the IK and OMPL documents and I didn't find an easier way for collision checking. Is there any demo or example to show how to add c...

I have tried to use simIK = coppeliasim.bridge.call('scriptClientBridge.require', ['simIK']) simIK = coppeliasim.bridge.require('simIK') But it cannot pass a Python function as an argument for validation callback in simIK.generatePath function. The error is about ValueError: cannot serialize unknown...
