Z1 Pro

Unitree Z1 Pro is a six-axis robotic arm designed for mobile robots and laboratory platforms. The 4.5 kg arm reaches 740 mm, carries at least 3 kg and repeats to approximately 0.1 mm. Its joints provide position and force control, force feedback and collision detection, while Ethernet connects the arm to a host running Ubuntu.

The Z1 platform accepts replaceable end actuators through an open programming and control interface. Unitree demonstrates the arm grasping, orienting and pouring from a bottle, and positions it for onboard manipulation, logistics and research. Maximum joint torque reaches 33 Nm and the arm uses a 24 V supply with current above 20 A. Z1 Pro remains a distinct higher-payload variant beside the 4.3 kg Z1 Air, which carries 2 kg at the same reach.
