Strange Behaviour

[Mike]

I am attaching a Barret gripper with a Kuka arm (LBR). I have disabled the script of the Barret gripper.
Everything was working fine. I was even able to control them through remote Python API.
Now when I simulate it, the gripper closes by itself. There are no API running to control gripper, but still it closes.

I tried with default script, ie the script along with Kuka arm with Barret script disabled. But the gripper closes though there are no instructions to control it.

What could have gone wrong?

Have a look at the joints of the gripper hand: they might be in position control and the specified target position might be different from the current position. Or, the joints might be in velocity control and a non-zero target velocity is specified.
It might help if you posted the scene.
