The Unitree D1 is a compact servo robotic arm: six axes plus a gripper, a 500 g payload and a reach of 550 mm, or 670 mm with the gripper included, in an aluminium-alloy arm of about 2.37 kg. It is offered as an arm for the Unitree Go2 quadruped, turning the robot dog into a small mobile manipulator for grasping and moving light objects in research and teaching.
Its joints are bus servos, powered from a 24 V supply at 2.5 A (up to 5 A) with a rated power of 60 W. Unitree gives the arm position, velocity and force control, through low-level interfaces for driving the servos directly and high-level interfaces for application work. Power comes in through a DC 5.5-2.1 connector, commands over RJ45, and a USB Type-C port is there for serial-port debugging. The arm can also be connected to external devices such as cameras or a mobile robot chassis.
It suits universities, AI labs and developers working on mobile manipulation, grasping and teleoperation on a legged base, and teaching labs that want a light arm students can program. With a 500 g payload it is sized for light objects and experiments, not for industrial handling.
This listing is one D1 arm. The Unitree D1-T, listed separately, is Unitree's teleoperation kit for remote manipulation and data collection, offered in dual-arm and quad-arm editions; choose the D1 when you need a single arm on a Go2 or another mobile base. How the arm mounts and connects to your Go2, which Go2 edition it needs, its repeatability and the package contents are confirmed in writing with the quotation.
Key Capabilities
-
6 axes plus a gripper: Six articulated joints position the integrated gripper for grasping and placing light objects.
-
500 g payload, up to 670 mm reach: The arm reaches 550 mm on its own and 670 mm with the gripper included.
-
About 2.37 kg in aluminium alloy: An aluminium-alloy build keeps the whole arm light for use on a mobile base.
-
Position, velocity and force control: The bus servos accept all three modes, through low-level interfaces for direct servo control or high-level interfaces for applications.
-
Simple power and data connections: A 24 V supply feeds a DC 5.5-2.1 connector, commands travel over RJ45, and a USB Type-C port handles serial debugging.
-
Ready for cameras and mobile bases: Unitree designs the arm to connect to external devices such as cameras and mobile robot chassis.
