Official 7-DOF collaborative robotic arm designed for the Unitree R1 humanoid robot platform. The R1-7a Standard features 7 degrees of freedom driven by low-inertia, high-speed inner-rotor PMSM bionic joint motors with high torque and high burst output, delivering a maximum joint torque of 44.3 lb·ft (60 N·m). Housed in a lightweight 12.1 lb (5.5 kg) metal body with engineering plastic components, it supports a 4.4 lb (2 kg) rated payload (up to 8.8 lb (4 kg) maximum load) and features industrial crossed-roller bearings. Each joint utilizes dual encoders for precise feedback. Supports flexible mounting (upright, side, inverted) and offers CAN/485 communication. Available in left-arm and right-arm mirror-image versions.
The Unitree R1-7a Standard Robotic Arm is a high-performance 7-DOF collaborative robotic arm specifically designed for the Unitree R1 humanoid robot platform. With 7 degrees of freedom and a maximum joint torque of 44.3 lb·ft (60 N·m), the R1-7a achieves human-like dexterity and robust load handling. Constructed with a metal body and engineering plastic components, it features industrial crossed-roller bearings and low-inertia, high-speed inner-rotor PMSM bionic joint motors with high torque and high burst output, ensuring high precision, fast response, and excellent heat dissipation in a lightweight 12.1 lb (5.5 kg) package.
