BrainCo Revo 2 Dexterous Hand
BrainCo Revo 2 is a 383 g, 160 mm bionic dexterous hand with 6 coreless motors driving 6 active joints and 11 DoF. It grips with ≥ 50 N (≥ 15 N pinch), holds ≥ 20 kg static, opens 100 mm thumb-to-index and closes in ≤ 0.65 s with 0.1° repeat accuracy. The Basic version talks RS485 and CAN FD on 12–28 V; Pro and Touch add EtherCAT, 12–64 V and tactile sensing. Python / C SDK for Linux, Windows and ROS.

Specifications
Motor performance
No-load, rated-load and stall figures retain their separate test conditions.
Stall torque and current are not continuous ratings. Check the duty cycle and starting load when choosing the driver and power supply.
Thermal limits by level
Product operating conditions, chip ambient ratings, package case limits and junction maxima remain separate.
