What makes it work
Unitree G1 Bionic Hand Revo 2 Touch
BrainCo's Revo 2 is a bionic dexterous hand for robot integration and research, providing 6 active joints and 11 degrees of freedom, with closed-loop servo control and RS485 / CAN FD communication for the Unitree G1 platform.
Closed-Loop Servo Control, Built for Integration
The Revo 2 Touch is a bionic dexterous hand designed for robot integration and research, providing 6 active joints across 11 total degrees of freedom. It supports RS485 and CAN FD communication interfaces, with SDK support for Linux, Windows, and ROS workflows. The hand includes closed-loop servo control, custom gesture definitions, and protection against current, stall, high temperature, and collision conditions — all in a lightweight 383g package available in Space Gray or Silver, with bulk color customization supported.
Four Pillars of the Revo 2 Touch

Dimensions & Degree of Freedom Distribution
160mm From Palm Base to Middle Fingertip
The Revo 2 Touch measures 160mm from the base of the palm to the tip of the middle finger, weighing 383g, with a maximum opening and closing distance of 100mm from thumb to index finger.
6 Active Joints, 11 Total Degrees of Freedom
The thumb has two active degrees of freedom for abduction and adduction, plus one passive degree of freedom for flexion and extension. Each of the remaining four fingers has one active degree of freedom for flexion and extension, plus one passive degree of freedom for flexion and extension.
RS485, CAN FD or EtherCAT, Located Beneath the Wrist
The Revo 2 Touch supports three communication interfaces — RS485, CAN FD, and EtherCAT — for communication and control, with the interface located below the wrist.
