Price comparison
UR3e: listed from $33,800
Mitsubishi ASSISTA RV-5AS-D: listed from $34,000
Difference: $200
At almost the same listed price, the decision rests on payload, reach and cell size.
Payload and reach
The ASSISTA carries 5 kg against 3 kg and reaches 910 mm against 500 mm. Assembly, machine tending, inspection and pick-and-place over a wider area favor the ASSISTA. Both arms publish ±0.03 mm repeatability.
Speed and weight
Universal Robots publishes a 3 m/s maximum tool speed for the UR3e. Mitsubishi publishes a maximum composite speed of 1,000 mm/s for the ASSISTA and 250 mm/s in collaborative operation. The UR3e weighs 11.2 kg, about a third of the 32 kg ASSISTA, and suits benches and in-machine mounting.
Controller and integration
The ASSISTA runs on the Mitsubishi CR800-05VD controller and mounts on the floor or ceiling, which suits plants already standardized on Mitsubishi Electric automation. The UR3e runs PolyScope with PROFINET, EtherNet/IP, Modbus TCP, ROS/ROS2 and UR+ accessories, and has a built-in ±30 N / ±10 Nm force/torque sensor.
