Gripper connected to UR3 can't pick any object - no friction.

I am working on the simulator, which can perform objects grasping with a robotic arm.

When I use my own robot model, it can perform grasping very well, but after replacing my manipulator with UR3 with my gripper connected, the robot can't pick any object. All objects are slipping from its fingers like there was no friction. In Gazebo GUI all properties of the gripper are the same for both robots.

Is it possible, that some properties, which prevents from grasping are propagated from UR manipulator to its gripper?

Any help will be appreciated.

One way to check what parameters were eventually loaded into Gazebo is to do File -> Save World As, and then dig through the saved SDF file to see what friction values were actually passed to the gripper.

Thank you Chapulina for smart advice. Unfortunately (or fortunately), those parameters in SDF file are all OK. This means that problem is probably hidden somewhere else.
