Unitree Servo Robot Arm D1

Unitree Servo Robot Arm D1

Overview
The Unitree D1 Servo Robotic Arm is a lightweight, high-performance 6-DOF robotic arm engineered for AI development, robot integration, and real-world research applications.
Weighing just 9.5kg and capable of reaching 0.84 metres, it combines strength and agility with cutting-edge servo control for seamless multi-axis coordination.
Whether you’re prototyping intelligent grasping, performing complex automation tasks, or extending the reach of a quadruped robot like the Go2 or B2, the D1 delivers the reliability and precision required for modern robotics applications. Featuring Unitree’s proprietary joint motors, full-link force control, and support for secondary development, it’s a flexible and future-ready platform.
