Technical extensions
Official page also reports arm repeatability ±0.05 mm (based on collaborative robots), 48 VDC power specification, low-level position-reference/tracking/temperature/overcurrent/communication monitoring and high-level current limiting. Configurations A/M differ in wheel count and battery; dual-PC architecture separates real-time robot control from user applications. Optional neck joint, gripper and mobility/interface expansions are described on the source page.
