Unitree D2

All-Metal Robotic Arm

Built for Outdoor Challenges

180° Elbow Folding,
Seamless Switching Between Two Configurations

A single arm can be securely positioned on a desktop to meet basic research needs; two arms can be combined for coordinated operation, serving as an embodied AI platform for algorithm validation and data collection.

Dual-Arm Mounting on a Quadruped,
Redefining the Boundaries of Outdoor Embodied Operations

Seamless compatibility with A2/As2, extending intelligent reach to the frontline

Dual-arm mounting enables operations in complex terrains such as forests and mountainous areas for inspection, rescue, and other applications, overcoming the limitations of fixed workstations.

  • High Payload Capacity, Stable Performance

    3 kg end-effector payload for stable operation. With a maximum load capacity of 5 kg, it handles tasks with ease.

  • Dynamic RGB Light Strip,

    Bringing a Sense of Life to the Robotic Arm

    18 RGB LEDs form a complete visual language for interaction, with multi-level dynamic lighting effects directly indicating the operating status.

  • Bio-Inspired Joints,

    Powerful Output

    Dual encoders enable precise closed-loop control, while crossed roller bearings balance rigidity and flexibility. High torque and powerful output redefine the limits of robotic motion.

Digital Twin Robotic Arm Control Platform

Designed for debugging, monitoring, and on-site maintenance, the platform integrates real-time visualization, parameter monitoring, and a complete set of maintenance tools. Complex motion planning is handled through a dedicated SDK, with clearly defined software and hardware functions for stable and efficient system operation.
