About this product

Revo3 is BrainCo's fully actuated five-finger hand for robotic manipulation, research and industrial automation development. It uses 21 independent motors: five active degrees of freedom in the thumb and four in each remaining finger. The manufacturer describes a backdrivable mechanism and provides C/C++, Python and ROS development support. Communication options include RS485, CAN FD and EtherCAT. Four configurations share the same actuation layout but differ in sensing, ranging from the non-tactile U21 to fingertip-force, palm-array and combined visual-tactile versions.
