ROKAE xMate SR3: listed from $15,200
Difference: $18,600
The xMate SR3 costs roughly 55% less
Reach and precision
Both arms carry 3 kg and repeat to ±0.03 mm. The SR3 reaches 705 mm, 205 mm more than the UR3e, which covers a wider bench from one position. Both have six-axis force sensing at the tool flange.
Speed and cycle time
Universal Robots publishes a 3 m/s maximum tool speed for the UR3e, twice the 1.5 m/s ROKAE publishes for the SR3. For high-volume pick-and-place, the UR3e can shorten cycle times.
Weight, power and ecosystem
The UR3e weighs 11.2 kg, about 2.6 kg less. The SR3 runs on 48 VDC with a compact xMate SR Cab and mounts at any angle. The UR3e runs PolyScope with PROFINET, EtherNet/IP, Modbus TCP, ROS/ROS2 and UR+ accessories.
