Used Universal Robots UR3 6-Axis Tabletop Collaborative Robot Arm (Cobot) with CB3 Controller
The Universal Robots UR3 is UR's most compact tabletop cobot. Weighing just 11kg, it features infinite rotation on its end joint (wrist 3), allowing effortless automated screw driving and tool manipulation without resetting axis limits. Its compact footprint makes it an ideal fit for tight electronics assembly cells, medical laboratory benches, and small machine tending stations.
