• The xMate CR20 costs roughly 55% less

For multi-line palletizing, a saving of this size per robot changes the payback calculation.

Reach and precision

Both arms carry 20 kg. The CR20 reaches 1798 mm, 48 mm more, and publishes ±0.05 mm repeatability against ±0.1 mm for the UR20. Both cover full-height pallets.

Speed and throughput

ROKAE xMate CR20

Universal Robots publishes a 5 m/s maximum tool speed for the UR20, against 3.5 m/s at the tool end for the CR20. On high-volume palletizing lines, the UR20 can shorten cycle times.

Protection, weight and sensing

The CR20 is sealed to IP67 against IP65 for the UR20, and both arms have force sensing at the tool flange. The UR20 weighs 64 kg, about 7 kg less, and runs PolyScope with PROFINET, EtherNet/IP, Modbus TCP, ROS/ROS2 and UR+ palletizing kits. The CR20 mounts at any angle and runs on the xMate Control Cab.
