Currently, my E pick vacuum gripper is connected to UR5. I am able to control the E Pick vacuum gripper via UR5 Flex-pendant. I am able to control UR5 via my PC (using ROS) by installing External Controller in UR5 and UR5 driver in my PC. Is there any way to control Gripper via my PC (ROS) without it being connected to my PC directly. It begins to connect to UR5 and UR5 connects to my PC. So, from the same ROS code, I can control both UR5 and gripper.
