We are testing the qb_device_driver communication_handle.launch on the UR5e. According to the instructions, for e series, we can just connect the cable from the hand to the wrist (no power connection to the control box required). And we can use the teach pendant to show some grasping demo in this way. However, when we want to use the QB-device package, it failed, we can not communicate with the hand from our computer. Are there any parameters we need to set for controlling the hand from a laptop in this situation (only one cable connect the hand to the arm wrist, see the picture in the attachment)?
Thanks in advance, any suggestions will be appreciated!
