Unitree R1 BrainCo Bionic Dexterous Hand Revo 2 Basic Version

The Unitree R1 BrainCo Bionic Dexterous Hand Revo 2 (Basic Version) is a high-performance, human-scale robotic end-effector designed for integration with the Unitree R1 and G1 humanoid platforms. Developed by BrainCo (a leader in BCI and prosthetic technology), the Revo 2 is engineered to mimic the form and functionality of a human hand, prioritizing a high power-to-weight ratio and precise control.

The “Basic Version” serves as the accessible entry point for researchers and developers who require bionic manipulation without the advanced multimodal tactile sensing found in the higher-tier “Touch” models.

Key Features

Ultra-Lightweight Bionic Design: Weighing only 383g (approx. the weight of six eggs), the hand is 20% lighter than many industry competitors, reducing the inertial load on the robot’s arm joints.
High Payload & Grip Force: Despite its compact size, it delivers a powerful 50N grip force and can support a static load of up to 20 kg, allowing it to handle heavy everyday objects like a full water jug.
Precision Actuation: Features 11 degrees of freedom (DoF) with 6 active joints, enabling complex gestures and adaptive grasping. It achieves a repeat accuracy of 0.1° for fine-motor tasks.
Human-Scale Ergonomics: At 16 cm in length, it matches the size of an average adult hand, ensuring it can interact with tools and environments designed for humans.

Comparison: Basic vs. Pro/Touch Versions

The Basic Version is optimized for movement and strength. While it supports position, speed, and current control, it lacks certain advanced features found in the higher versions:

Communication: Basic uses RS485/CAN-FD; the Pro/Touch versions add EtherCAT support.
Tactile Feedback: The Basic version does not include the 3D tactile perception system (pressure, friction, and force direction sensing) found in the Revo 2 Touch.
Voltage: The Basic version operates up to 28V, whereas the Pro/Touch versions support a wider range up to 64V.

Ideal Applications

Humanoid Research: Developing locomotion and balance while carrying objects.
Service Robotics: Simple pick-and-place tasks in domestic or laboratory settings.
Education: Teaching kinematics and bionic control at the university level.
AI Training: Using reinforcement learning to master human-like grasping gestures.
