Unitree Z1 Robotic Arm

Unitree's lightweight 6-axis robot arm, mountable on a quadruped's back for mobile manipulation.

Z1 is a lightweight 6-degree-of-freedom robot arm from Unitree Robotics, offered in AIR and PRO editions: they weigh about 4.3 kg and 4.5 kg, carry payloads of 2 kg and over 3 kg, have a reach (working radius) of about 740 mm, and repeat positioning within about 0.1 mm. Unitree's site says it's designed to pair with the company's mobile robots, such as the Aliengo and B1 quadrupeds, mounting on a quadruped's back to form an “arm-equipped quadruped” for legged mobile-manipulation tasks like opening doors or picking things up off the ground; it can also be bolted to a tabletop on its own for manipulation research.

ExampleMounting a Z1 on the back of a Unitree B1 quadruped lets the robot dog walk while using the arm to reach for an object on the ground.
