Change frame of a link/joint without moving the link joint

Hello,

Is there a way to change the frame of a link/joint at runtime? I am asking because I would like to change the axis of rotation of a joint at runtime (by editing the frame in which this axis is expressed).

Note: Entity::SetWorldPose() is not an option because it changes the position of the underlying link/joint and disturbs the momenta.

Kind regards,

Antoine.

Aargh! We need this to simulate mecanum wheels... do you know if there exists (paid) gazebo support that could fast track the implementation of this feature? (issue created here).

It sounds like you are creating a plugin to simulate the mecanum wheels, is that correct? Have you tried creating a mechanically correct model of the wheel?

You are right indeed. I am a bit scared of the stability and performance of simulating a real mecanum wheel though but that may be worth a test. Will investigate this solution... Regards
