The Unitree D1 Servo Robot Arm Kit is a 6-DOF precision robotic arm with a 600mm maximum reach, Ethernet (RJ45) control interface, and a full joint range of ±90° to ±135° across all six axes. Engineered for research, automation, and custom robotic system integration — built by the team behind the G1 humanoid and B-series quadrupeds.

Six Degrees of Freedom. Engineered for Precision.
The D1 Servo Robot Arm Kit brings Unitree's robotics engineering expertise to the tabletop. Its 6-DOF joint architecture delivers a full range of motion across all six axes — from ±90° on the mid-range joints to ±135° on the base and wrist — enabling complex manipulation sequences, precise end-effector positioning, and repeatable task execution. The Ethernet (RJ45) control interface provides a robust, low-latency communication link for integration with research platforms, custom controllers, and automation software stacks. With a 600mm maximum reach and 500g payload capacity, the D1 is sized for real-world manipulation tasks while remaining compact enough for lab and bench deployment. Whether you're developing manipulation algorithms, building a pick-and-place system, or integrating a robotic arm into a larger platform, the D1 delivers the performance and flexibility to move your work forward.

Full 6-DOF Joint Architecture — Six independently actuated joints with a range of ±90° to ±135° deliver the reach, dexterity, and repeatability required for complex manipulation tasks and research applications.

Ethernet Control Interface — RJ45 (ETH) control communication provides a robust, low-latency connection for integration with research platforms, custom software stacks, and automation control systems.

Research & Automation Ready — 600mm maximum reach, 500g payload capacity, and a compact form factor make the D1 ideal for tabletop automation, pick-and-place systems, HRI research, and university robotics labs.
