Metric Allen key set (4 mm)

Electrical installation :

Pass your cable along the robot arm, make sure you have enough cable forgiveness to allow the UR to move freely in all directions. Attach with tie-wrap (or any cable holding system, may look better then tie-wraps...)

Software setup :

Get the driver package for Robotiq Gripper at support.robotiq.com (look into each of the product section)
