- 21 degrees of freedom 21 total DOF—significantly more than the Revo 2's 11—distributed to mirror human hand kinematics and support in-hand manipulation beyond simple open-close grasping.
- Direct-drive backdrivable joints Fully direct-drive, backdrivable joint architecture provides smooth motion, low transmission backlash, and the force-control sensitivity required for stable in-hand object manipulation.
- Full-palm tactile sensing at 0.01 N resolution Full-palm tactile sensing layer with 0.01 N force resolution enables contact-aware manipulation and precise grasp force regulation across the entire palm surface.
- Fingertip visuotactile sensing at 130 µm resolution Fingertip visuotactile sensors detect approximately 130 µm surface deformation, supporting fine-grained contact detection and in-hand object state estimation.
- Demonstrated complex manipulation tasks Public demonstrations include Rubik's Cube solving, paper cutting, scissor use, bead handling, and string play—tasks requiring kinematic complexity, sensing, and in-hand dexterity together.
- Embodied AI and humanoid robotics positioning Designed for humanoid robots, mobile manipulators, teleoperation systems, and embodied learning platforms where human-level in-hand dexterity is the development target.
Description
The BrainCo Revo 3-21 Basic is a next-generation dexterous robotic hand built to push beyond the kinematic limits of conventional multi-finger end-effectors. Its headline specification is 21 total degrees of freedom—nearly double the 11 DOF of the Revo 2 series—distributed to more closely mirror human hand capability and enable in-hand manipulation rather than just static grasping. A fully direct-drive, backdrivable joint architecture delivers the smooth motion, low backlash, and force-control resolution that complex manipulation tasks demand, while a full-palm tactile sensing layer at 0.01 N resolution and fingertip visuotactile sensing capable of detecting approximately 130 µm deformation provide the sensory fidelity needed for stable in-hand object handling.
Public demonstrations of the Revo 3 have included paper cutting, Rubik's Cube solving, string play, bead handling, and scissor use—tasks that require not only kinematic range but also the sensing integration and control resolution to move objects within the hand without dropping them. BrainCo's engineering base for the Revo 3 builds on the commercially established Revo 2 program, which produced a hand delivering 50 N grip force and 20 kg maximum load at 383 g, providing a credible foundation for the Revo 3's more ambitious dexterity and sensing targets. The Revo 3-21 Basic is positioned for embodied AI systems, humanoid robotics research, and advanced manipulation development teams seeking human-level in-hand dexterity at a commercial product scale.
