Thanks for your work！
I would like to ask, what else needs to be done before running "roslaunch onrobot_control onrobot_gripper.launch".
I run the ur_robot_driver of Universal_Robots_ROS_Driver and run the "roslaunch onrobot_control onrobot_gripper.launch".
I run the ur_robot_driver of Universal_Robots_ROS_Driver and run the moveit of ur5 with girpper(but the girpper can not do in gazebo),then run the "roslaunch onrobot_control onrobot_gripper.launch".

But, your code will error：
"src/onrobot_ros-master/onrobot_control/src/onrobot_control/gripper_control_server.py", line 23, in init
self._limit, self._mimics = _get_joint_info(self._joint_name)
