① Adopts a circulation mode with centralized oil supply from the main oil station and precise control by local oil stations, delivering more accurate control and reducing the workload of oil replenishment and filter replacement for individual oil stations.
② Adopts a sensor-based error-proofing design installed on the tooling racks, eliminating the space constraint conflict of adding mechanisms at the test stations.

① Adopts an integrated design of test bench and oil station, which saves space and reduces pressure drop caused by long pipelines.
② Adopts an integrated oil-slinging station on the test bench, which shortens the robot cycle time and ensures environmental cleanliness.
