However, that only gives the normal contact force and not really the torque acting on the link. We have made a feature request to the PhysX team to provide a 6-DoF wrench sensing on the links. Will have to check if that is going to be in the coming release of Isaac Sim or not. ...

I viewed in https://github.com/NVIDIA-Omniverse/OmniIsaacGymEnvs#a-note-about-force-sensors that there was a bug in the force sensors. Is it still the case ? If so, is it also present in the class of the contact force sensors (omni.isaac.sensor._sensor)?philipp.reist 2023 年2 月 ...
