_motion_planning.acquire_motion_planning_interface()

Returns RuntimeError:
Failed to acquire interface: omni::isaac::motion_planning::MotionPlanning (pluginName: nullptr)

Why is this error appearing, and what can I do to fix this?

Thanks in advance!

Hi Liiila,

I’ve been trying to control the franka panda robot with end effector cartesian pose, following codes under the sample directory.

However, I cannot seem to acquire the motion planing interface through the code in the image. (dynamic control interface works)

Are there better ways of having panda franka to reach a certain cartesian position and orientation?

Thanks,
twjhlee

Hi Liiila,

The problem was in the experience json.
It worked as soon as I changed the experience path to isaac-sim.json

Thanks,
