Unitree R1 BrainCo Bionic Dexterous Hand Revo 2 Haptic Version

The Unitree R1 is a high-performance humanoid robot that can be equipped with the BrainCo Bionic Dexterous Hand Revo 2 (Haptic Version). This combination represents the cutting edge of “Embodied Intelligence,” where a robotic body is paired with human-like sensing and manipulation capabilities.

While the Unitree R1 provides the mobile “body” (1.2m tall, 25kg, 26 joints), the Revo 2 Haptic Version acts as its sophisticated interface for interacting with the physical world.

Product Overview: BrainCo Revo 2 (Haptic Version)

The Revo 2 is an ultra-lightweight, high-precision bionic hand designed by BrainCo, a leader in brain-computer interface (BCI) technology. The Haptic/Touch version is the flagship model, featuring a dense array of multimodal tactile sensors that allow a robot to not just “grip” but truly “feel” objects.

Static Payload	20kg (can lift a full office water jug)
Degrees of Freedom	11 DoF (with 6 active joints)
Precision	0.1 mm sub-millimeter repeat accuracy
Noise Level	< 50 dB (quieter than a standard office)
Connectivity	RS485, CAN-FD, EtherCAT

Core Features & Technologies

1. Multimodal Tactile Perception (Haptic System)

Unlike the Basic or Pro models, the Haptic/Touch Version integrates 3D tactile sensors directly into the finger structures. This allows the hand to perceive:

Pressure & Friction: Detecting how hard it is holding an object to prevent slipping or crushing.
Force Direction: Understanding the vector of resistance when performing tasks like turning a key.
Texture & Hardness: Distinguishing between a soft fruit and a hard tool.
Proximity Sensing: Detecting the presence of an object before physical contact occurs.

2. Advanced Control Algorithms

The hand utilizes Adaptive Impedance Control and Adaptive Compliance Control. These allow the hand to “give” slightly when it encounters an obstacle, mimicking the natural flexibility of human tendons and preventing damage during delicate tasks like striking a match or handling glassware.

3. Human-Scale Ergonomics

At 16 cm long, the Revo 2 is sized similarly to an average adult female hand. Its “millimeter-level subtraction” design ensures it fits standard human tools and gloves without losing the 20kg high-load capacity required for industrial or home service tasks.

4. Safety & Durability

Intelligent Protection: Built-in safeguards against overcurrent, overvoltage, overheating, and impact.
Environmental Resilience: Designed for laboratories, medical research, and domestic service environments.

Use Cases

Humanoid Robotics: The primary hand for the Unitree R1/G1 series to perform fine-motor tasks (sorting, assembling, cooking).
Prosthetics: Leveraging BrainCo’s BCI heritage to provide amputees with intuitive, mind-controlled movement.
Medical Research: Used in teleoperation where a doctor “feels” what the robot feels during a procedure.
