Official 7-DOF bionic robotic arm specifically configured for seamless integration with the Unitree As2 industrial quadruped robot. The R1-7a As2 Standard combines the high-dexterity manipulation of the R1-7a arm with the dynamic mobility of the As2 platform. Featuring 7 degrees of freedom driven by low-inertia high-speed inner-rotor PMSM motors delivering 44.3 lb·ft (60 N·m) max joint torque, housed in a lightweight 12.1 lb (5.5 kg) metal and engineering plastic body. Includes specialized mounting hardware for the As2 backplate, industrial crossed-roller bearings, dual encoders, and CAN/485 communication. Available in left-arm and right-arm mirror-image versions. No RGB camera included.
The Unitree R1-7a As2 Standard Robotic Arm is a complete mobile manipulation solution designed to transform the Unitree As2 industrial quadruped into a highly capable, mobile robotic worker. Building on the proven R1-7a platform with its 7 degrees of freedom and 44.3 lb·ft (60 N·m) maximum joint torque, the As2 Standard variant is optimized for dynamic, on-the-move operation.
The arm features low-inertia high-speed inner-rotor PMSM bionic joint motors with high burst output, housed in a lightweight 12.1 lb (5.5 kg) metal body with engineering plastic components to minimize the payload impact on the quadruped's dynamic balance. The package includes the specialized As2 mounting interface and hardware for secure, vibration-resistant attachment to the robot dog's back. Constructed with industrial crossed-roller bearings and featuring dual encoders per joint for precise feedback even during locomotion. Supports flexible end-effector attachment and offers robust CAN/485 communication for seamless integration with the As2's control architecture.
7 independent joints driven by low-inertia high-speed inner-rotor PMSM motors. High burst output enables robust manipulation and dynamic tasks while the quadruped is in motion.
Comes with specialized mounting hardware and interface designed specifically for the Unitree As2 backplate. Ensures stable, vibration-dampened attachment during locomotion.
Optimized metal and engineering plastic construction minimizes weight, preserving the As2 robot's agility, speed, and battery endurance while carrying the arm.
Each of the 7 motors is equipped with a dual encoder system for redundant, high-resolution position feedback, ensuring precise trajectory tracking even on uneven terrain.
