@jtigue-bdai, shall we also include in this PR, adding a corresponding action class, i.e., OperationSpaceControllerAction/Cfg, here? This would be nice for being able to interface it with the action manager, and such exist for other controllers.

[jtigue-bdai]

Yeah I think that would be a good addition with this effort.

@jtigue-bdai At the moment I do not have push access to this PR branch.

Would you prefer I create a new PR from my own fork to integrate into this PR (so there would be two different PRs for the same topic), or would you like to give me push access to this branch? If you will give access, could you do it for both @ozhanozen and @sbtc-sipbb?

[jtigue-bdai]

Sorry @ozhanozen my intention was for you to push to this branch, but let me check with the dev team this morning and I will get back to you.

[jtigue-bdai]

@ozhanozen I talked with the team. Because this repo is setup within the isaac-sim org, the best way moving forward will be to have you create the PR from your fork and to the isaac-sim/isaac-lab. We can then just close this one and I can give you reviews you your branch.

Sorry for the confusion, I didn't realize some of the restrictions we had setup.

[ozhanozen]

@jtigue-bdai no problem. I have created a new PR from my fork, #913, as you suggested, and we can work on it.

You can close this PR.
