2013-03-08 15:14:28 -0600 asked a question Sticky Objects? PR2 Simulation, objects stick to gripper

I have troubles with gazebo models that stick to the PR2 gripper. The robot pushes objects with the gripper, not using the gripper for grasping but just to push. When the gripper is retracted, the objects that were pushed away are pulled back with the gripper again, as if there was glue between the gripper and the object.

Can this behavior be adjusted via the SurfaceParameters ?

Any other thoughts?

Thank you!
