BrainCo Revo 3 Basic Robot Hand

Key Features & Specifications

1. Human-Equivalent Dexterity

With 21 Degrees of Freedom, the Revo 3 can replicate nearly every movement of a human hand. This allows for complex manipulation tasks that were previously difficult for robotic hands, such as:

• Solving a Rubik’s Cube.

• Performing intricate rope/knot tricks.

• Delicate tool handling (e.g., using scissors or a pipette).

2. High Performance & Durability

• Load Capacity: Capable of a 30 kg static load and a whole-hand power grasp force of approximately 50N.

• Precision: Features a repeatability accuracy of 0.1mm, making it suitable for light electronics assembly.

• Speed: A rapid open/close time of roughly 0.8 seconds, allowing for reactive grasping.

3. Construction & Hardware

• Materials: Built using Aerospace-grade Aluminum Alloy for the internal structure and Food-grade Plastic for the exterior casing.

• Drive System: Utilizes high-precision micro-motors with direct-drive or optimized transmission to maintain a lightweight profile (approx. 540g).

• Communication: Supports RS485 and CAN/CANfd protocols as standard, ensuring compatibility with major robot controllers and the Unitree G1/H1 humanoid platforms.

Best Use Cases

The Revo 3 21 Basic is specifically positioned for:

• Embodied AI Research: Training reinforcement learning models that require high-DoF action spaces.

• Humanoid Development: Serving as the end-effector for research-grade humanoids.

• Education: A robust platform for universities to explore bionic control and kinematics without the budget overhead of tactile-sensing arrays.

Note: While the Revo 3 Basic includes position and current sensors for anti-pinch and anti-fall protection, it lacks the “Touch” model’s ability to sense texture, friction, and force direction.
