The \"V-Touch\" designation refers to this visuotactile capability: a small embedded camera behind a translucent elastic fingertip membrane captures deformation patterns as the fingertip contacts an object, enabling detection of surface deformation at approximately 130 micrometers while simultaneously using visual input to interpret object geometry and surface properties. BrainCo, founded at Harvard University's Center for Brain Science and holder of more than 360 patents in brain-computer interface and related fields, designed the Revo 3 series to bring prosthetics engineering heritage into commercial robotic end-effectors for humanoid robots and embodied AI platforms.\u003c\/p\u003e\u003cp\u003eWith 21 degrees of freedom — substantially closer to the human hand's approximate 27 DoF than most competing platforms — the Revo 3-21 V-Touch enables movement patterns including in-hand object rotation, finger gaiting, and tool manipulation. The direct-drive joint architecture eliminates transmission friction, making motor current a direct proxy for contact force across all 21 joints simultaneously. A modular design supports different finger configurations for specific task adaptation, and the hand communicates over EtherCAT, CAN FD, and RS-485 across a 12–80 V supply range, making it compatible with diverse humanoid and industrial robot platforms.\u003c\/p\u003e","brand":"BrainCo","offers":[{"title":"Default Title","offer_id":50186452828397,"sku":null,"price":26838.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0803\/2613\/1949\/files\/brainco-revo-3-21-basic-robot-hand-right_1_1.jpg?v=1782728880","url":"https:\/\/robotixmarket.co.uk\/products\/brainco-revo-3-21-v-touch-visuotactile-robot-hand","provider":"Robotix Market","version":"1.0","type":"link"}
