Revo 2

The 2025 Revo 2 is far lighter than its predecessor Revo 1: it weighs 383 g at 160 mm length yet keeps a five-finger grip of at least 50 N, a pinch of at least 15 N and a load of at least 20 kg.

Six motors in the hand give six active degrees of freedom, five passive ones make eleven; the thumb flexes 59 degrees with 90 degrees of auxiliary motion, the fingers flex 81 degrees, and positioning accuracy is 0.1 degree.

BrainCo sells three editions: Basic (codes XRL/XRR) with RS485 and CAN-FD at 12 to 28 V, Pro (XEL/XER) adding EtherCAT and 12 to 64 V, and Touch (XTL/XTR) with multi-dimensional fingertip tactile modules for pressure, friction, direction and proximity.

All editions sense position and current and include temperature and collision protection, with position, velocity and current control through a Python and C SDK plus ROS. The hand is offered as an option for Unitree humanoids, among them the Unitree G1, the Unitree H2 and the Unitree R1, and for research.
