Topic Description

I want to do robot action(pick and place) using action graph. I already follow the instructions in omni. doc.

The different thing compared to omni.doc(franka robot) is that I use different robot. (Base is yaskawa, and the gripper is something i find in the forum).

I made the action graph same as the omni.doc.

Then, When I click play, I got the error like this:
"OmniGraphError : Attempted to access an invalid object.

How Can I solve this problem?

Could you please upgrade to the current version of Isaac Sim, 4.2.0? Which Omni documentation are you referencing?

The documentation referencing now is this :
OmniGraph: Pick-and-Place Controller Node — Omniverse IsaacSim

Thank you for your reply!

Please let me know if you are still encountering this issue with version 4.2.0. If so, kindly share the detailed steps so we can replicate it.
