The UR3 is a tabletop robot with a payload of 3 kg and a weight of 11 kg. It allows for 360° rotation on all wrist joints and infinite rotation on the end joint, and has the capabilities to function efficiently as the second member of a two-man team or as a standalone operator.
From pick-and-place and assembly to polish, glue and screw applications, the robot is intended to enable manufacturers to maintain uniform product output. For example, it can pick up screws, mount and tighten them while applying the correct torque.
Additionally, the unit can be deployed in confined workspaces where the construction of large safety guarding is not feasible. Likewise, it can be tasked to operate in environments with toxic or hazardous materials.
The robot has 15 adjustable safety settings. One of these is the force-sensing feature that enables the unit to limit the force on impact if it encounters an obstruction. As a default setting the robot is able to sense a force of 150 N, but it can be programmed to cease all movements if it encounters a force as low as 50 N along its path of motion.
The robot features 0.1 mm repeatability and can follow the outline of a surface by ‘feel’ rather than through the programming of precise movements and coordinates, which otherwise would require more than 100 data points programmed into the application.
