Official 13-DOF collaborative robotic arm system designed for the Unitree R1 humanoid robot platform. The R1-7a Professional E includes all features of the R1-7a Standard arm and comes equipped with the BrainCo five-finger dexterous hand Revo 2 Basic (with RGB camera). With 13 total degrees of freedom (7 arm joints + 6 dexterous hand DOF across 11 joints), 0.1° repeat control accuracy, low-inertia high-speed inner-rotor PMSM motors delivering 44.3 lb·ft (60 N·m) max joint torque, and a compact 6.3" (160 mm) hand height, it provides a complete five-finger dexterous manipulation solution with integrated visual feedback. Available in left-arm and right-arm mirror-image versions.
The Unitree R1-7a Professional E Robotic Arm is a complete 13-DOF manipulation system designed for the Unitree R1 humanoid robot platform. Building on the proven R1-7a Standard arm with its 7 degrees of freedom and 44.3 lb·ft (60 N·m) maximum joint torque, the Professional E variant adds the BrainCo five-finger dexterous hand Revo 2 Basic (with RGB camera) as standard equipment, bringing the total system to 13 degrees of freedom (7 arm joints + 6 dexterous hand DOF distributed across 11 joints).
The arm features low-inertia high-speed inner-rotor PMSM bionic joint motors with high torque and high burst output, housed in a lightweight metal body with engineering plastic components. The integrated BrainCo Revo 2 Basic dexterous hand features a five-finger architecture with 6 DOF, 11 joints, 0.1° repeat control accuracy, and a height of 6.3" (160 mm) from middle fingertip to palm root. The hand includes an integrated RGB camera for visual feedback. Each arm joint utilizes dual encoders for precise feedback. Supports flexible mounting (upright, side, inverted) and offers high-speed 485 communication for the arm.
7 arm joints plus 6 dexterous hand DOF (across 11 joints) deliver a fully integrated five-finger manipulation solution. BrainCo Revo 2 Basic hand with RGB camera included.
Five-finger dexterous hand with 6 DOF, 11 joints, 0.1° repeat control accuracy, and 6.3" (160 mm) height. Human-like dexterity for complex manipulation tasks.
7 independent joints driven by low-inertia high-speed inner-rotor PMSM bionic joint motors. High burst output enables robust manipulation and dynamic humanoid tasks.
Each of the 7 arm motors is equipped with a dual encoder system for redundant, high-resolution position feedback and reliable closed-loop control.
Supports upright, side, and inverted mounting configurations. Adapts to various humanoid robot body configurations and workspace requirements.
High-speed 485 communication protocol for the arm. Robust, noise-resistant protocol suitable for humanoid robot integration and industrial environments.
The R1-7a Professional E comes equipped with the BrainCo Revo 2 Basic five-finger dexterous hand, providing advanced human-like manipulation capability with integrated visual feedback:
The BrainCo Revo 2 Basic features a five-finger architecture with 6 DOF across 11 joints, enabling human-like dexterity and versatile grasping patterns:
Opposable thumb design enables precision pinch grasps, power grasps, and complex in-hand manipulation. Critical for human-like dexterity.
Independent articulation for pointing, trigger-style manipulation, and fine tactile exploration. Supports precision and power grasp modes.
Central finger provides stability and force distribution during object manipulation. Key contributor to power grasp envelope.
Supports power grasp completion and lateral stabilization. Works in coordination with pinky for secure wrapping of large objects.
Completes the five-finger architecture for adaptive grasping and in-hand manipulation of complex objects. Enhances grasp security.
11 joints distributed across five fingers with 6 active degrees of freedom. Enables complex finger coordination and human-like manipulation patterns.
The BrainCo Revo 2 Basic dexterous hand features an integrated RGB camera, providing critical visual feedback directly at the point of manipulation:
The R1-7a Professional E is available in left-arm and right-arm versions, specifically designed for bimanual humanoid robot integration:
