The BrainCo Dexterous Hand Revo 3 is a next-generation robotic dexterous hand for embodied AI, humanoid robotics, manipulation research, and advanced end-effector development. Public launch reporting describes Revo 3 as a 21-degree-of-freedom hand built around a direct-drive, backdrivable joint architecture for more precise and compliant manipulation than simple open-close grippers. The BrainCo Revo 3 dexterous hand is available in three configuration variants—U21, U21T, and U21VT—all built on the same 21‑DOF direct‑drive architecture, but differentiated by their tactile and interaction capabilities. The U21 variant provides the standard 21‑DOF configuration suitable for general integration needs. The U21T variant enhances this with tactile sensing for applications requiring contact or pressure detection. The U21VT variant further expands the system with a visual‑tactile fusion package, offering the highest level of interactive feedback. Before integration, please confirm the hand orientation (left/right) and the final interface package, and refer to the configuration sheet for tactile or visual‑tactile module details.

The Shopify product includes U21, U21T, and U21VT variants with SKUs BrainCo-Revo3-U21, BrainCo-Revo3-U21T, and BrainCo-Revo3-U21VT. What does the 21 in U21 refer to? BrainCo SDK release notes confirm Revo3 support for 21-degree-of-freedom motor control, so U21 is presented as the 21-DOF Revo 3 configuration family. Does the official SDK support Revo3? Yes. BrainCo's official SDK documentation states that the SDK supports Revo 1, Revo 2, and Revo3 series devices. Which programming languages are supported? The BrainCo Hand SDK documentation lists Python and C++ development support. Which communication protocol should I plan for? The current BrainCo SDK protocol table lists RS-485 support for Revo3. Confirm the final protocol and connector package for the selected U21, U21T, or U21VT configuration before integration. Does Revo 3 support tactile sensing? Public launch reporting describes Revo 3 configurations with full-palm tactile sensing and fingertip visuotactile sensing. Because the full first-party variant matrix is limited, confirm the exact tactile package for U21T and U21VT before ordering or integration. What Revo3 examples are listed by BrainCo? BrainCo SDK release notes list Revo3-specific examples including revo3_motor.py, revo3_teaching.py, and revo3_benchmark.py. Is this suitable for embodied AI research? Yes. A 21-DOF robotic hand with SDK support is suitable for humanoid robotics, manipulation research, teleoperation, imitation learning, and embodied AI experimentation. Why are some mechanical specifications omitted? Variant-specific Revo 3 dimensions, weight, payload, connector model, and complete electrical data were not confirmed from a first-party Revo 3 parameter table during this rewrite, so they are intentionally omitted to avoid mixing in unverified data.
