Hi Everyone,

I'm trying a simple example of a robot grasping an object. The gripper is simply paramerized as a cylinder base with two cuboid as fingers and the object to grasp is a simple cuboid. the problem is that when the grasp is performed, there is no collision between fingers and object, as they go into the object, as showed in the following photo.

Anyone know why is happening that, I have defined the collision element in the sdf of the objet and in the urdf of the gripper. I'm using Ode engine with default parameters and gazebo 11.
