All-metal mechanical arm built to withstand outdoor challenges
D2 Robotic Arm
The Unitree D2 robotic arm features an all-metal chassis, weighing 5.9kg net. It offers 7 degrees of freedom plus a gripper, with an arm length of 633mm and a gripper working radius of 780mm. The end-effector payload is 3kg, with a maximum load capacity of 5kg. An elbow fold angle of 180° enables dual-mode switching, allowing dual-arm mounting on A2/As2 quadruped robots for outdoor embodied tasks.

Features
Features
Elbow 180° Fold – Seamless Dual-Mode Switching: Single-arm stable on desktop for basic research; dual-arm synergy transforms into an embodied AI foundation.
Quad Dual-Mount: Compatible with A2/As2, enables deep forest patrol and mountain rescue operations in complex terrain, breaking free from fixed workstations.
High Load, Stable Performance: Steady operation at 3kg payload, up to 5kg max capacity.
Dynamic RGB Life Strip: 18 RGB LEDs create a complete visual interaction language, with multi-level dynamic lighting effects that provide direct feedback on operational status.
Bionic joints with powerful output: dual encoders for precise closed-loop control, crossed roller bearings for optimal rigidity and flexibility, delivering high torque and explosive performance.
Digital Twin Robotic Arm Control Platform: Integrates real-time visualization, parameter monitoring, and comprehensive O&M tools; complex motion planning is handled by our professional SDK.
