Unitree Z1 Review Summary
The Z1 is built to ride on other robots. At 4.5 kg it is light enough to be carried by a quadruped robot, and it runs from a 24 V supply. It has force control and collision detection in every joint and an open programming interface on Ubuntu. Its accuracy of about 0.1 mm is adequate for manipulation research, and the maker itself warns that the low gear ratios can cause position error and shaking unless the control is tuned. It is a research and development arm, not a factory cobot. When this review was written the maker's shop listed the Z1 Pro as backordered.
