I want to simulate pick and place in Gazebo with a Robotiq gripper. I can grasp objects, I detect the contact, that is published in gazebo topics and that I use in my gripper controller, but sometimes the gripper "go through the object" -see here- and I can't move the object (here it is a glass).

The object is the plastic_cup from gazebo_library (see below). I just added kp and kd, because I couldn't grasp the glass at all, I think the collision was to big, so I simply added the kp and kd parameters from the coke can -fom gazebo library too-. I don't know well how to define these parameters.

    <model name='plastic_cup'>
      <link name='link'>
        <pose>0 0 0.065 0 -0 0</pose>
        <collision name='collision'>
        <visual name='visual'>
      <pose>-1.55427 -1 0 0 -0 0</pose>

What happens? Why can't I move the objects I grasp?

Sounds like a pure Gazebo question that should be asked on http://answers.gazebosim.org/questions/ . Besides that, describing the types of Gazebo object that you see the issues with would help.

Ok, thanks

I meant the "type of Gazebo object" as, how it's implemented. If it's SDF/URDF or mesh file etc., sharing code would be the best if that's possible.

Hi, why did you close the question?

As I said, your question should be the best suitable on Gazebo's Q&A forum, not here.
