BrainCo Revo 3

BrainCo Revo 3

The BrainCo Revo 3 is a full size, five finger dexterous robotic hand developed by BrainCo, a neurotechnology and robotics company headquartered in Hangzhou, China, with additional operations near Boston, Massachusetts. Released on April 10, 2026, the Revo 3 is the company's most advanced end effector to date and is positioned as the world's first open ecosystem dexterous hand to combine more than 20 degrees of freedom with full palm tactile sensing and fingertip visuotactile perception.

With 21 active degrees of freedom built entirely on direct drive, backdrivable joints, the Revo 3 is designed to move dexterous manipulation beyond simple grasping toward genuine in-hand manipulation, the ability to reposition, rotate and finely control objects within the fingers the way a human hand does. The platform builds on BrainCo's unique lineage in neural controlled prosthetic hands, giving the company an unusually deep foundation of real world human contact mechanics data compared with robotics first competitors.

The Revo 3 is offered in multiple configurations, commonly identified as the Revo 3 Basic, Revo 3 Touch and Revo 3 Vision (also referenced as the Revo 3-21 or V-Touch), allowing buyers to match sensing capability and cost to their application. For research laboratories, humanoid robot manufacturers and embodied AI teams evaluating a dexterous hand for sale in this class, the Revo 3 represents one of the most complete sensing and control packages currently available.

Design and Features

Human Scale Anatomy

The Revo 3 measures 215 × 105 × 50 mm, closely matching the proportions of an adult human hand. Its 21 degrees of freedom are distributed anatomically, with 4 degrees of freedom in each of the four fingers and 5 in the thumb. Every finger can achieve full opposition, touching the palm, and the hand reportedly exceeds the range of a human hand in Kapandji opposition testing, a clinical benchmark for thumb dexterity.

Direct Drive, Backdrivable Joints

Unlike many dexterous hands that rely on tendons or high ratio gearboxes, the Revo 3 uses a fully direct drive, backdrivable joint architecture. This design delivers three practical advantages: precise force control at the joint level, natural compliance when the hand contacts objects or people, and the ability to be physically guided by hand for teaching and demonstration workflows. The result is manipulation that is both faster and safer than traditional geared designs.

Dual Layer Tactile Sensing

The defining feature of the Revo 3 is its dual layer sensing system, available on the Touch and Vision configurations:

• Full palm tactile array. Pressure sensing across the entire hand surface at 0.01 N resolution, capturing pressure distribution, friction, force direction and proximity across all contact zones simultaneously.
• Fingertip visuotactile sensors. Optical and force sensing embedded in each fingertip, capable of resolving approximately 130 μm of surface deformation, enabling sub millimeter alignment before a grasp is committed.

Historically, robotic hands have been tactilely blind, inferring grip security from external cameras. The Revo 3 moves that perception inside the hand itself, enabling slip detection, contact aware gripping and stable in-hand manipulation of delicate or irregular objects.

Technology and Specifications

Core Specifications

Control and Connectivity

The Revo 3 runs a 500 Hz control loop across four operating modes, allowing developers to choose between precise position control, compliant force position behavior, admittance response for safe interaction, and zero torque mode for free movement and kinesthetic teaching. Industrial grade EtherCAT, CAN FD and RS-485 interfaces, combined with the wide 12–80V operating range, make the hand suitable for direct integration into humanoid robot arms, collaborative robots and custom research platforms without additional power conversion hardware.

Software Ecosystem

BrainCo supports the Revo 3 with C++ and Python SDKs, ROS 2 drivers, robot description assets and simulation resources, alongside official example programs covering motor control, teaching mode and high frequency latency testing. The platform is positioned as an open ecosystem with sim2real integration and one click deployment, allowing manipulation policies trained in simulation to transfer to the physical hand. This tight simulation to hardware pipeline is particularly valuable for imitation learning and manipulation data collection at scale.

Applications and Use Cases

Humanoid Robotics

The Revo 3 serves as a five finger end effector for humanoid robot platforms, giving general purpose robots the dexterity to handle tools, containers, fabrics and everyday objects designed for human hands. Its human matched dimensions allow direct mounting on humanoid wrists without redesigning workspaces.

Embodied AI and Manipulation Research

Universities and AI laboratories use the Revo 3 to study manipulation policies, tactile aware control loops and real world object interaction. The combination of rich contact sensing, backdrivable joints and open SDK access makes it a strong platform for reinforcement learning and imitation learning research.

Precision Assembly and Industrial Tasks

The fingertip visuotactile sensing enables tasks that external cameras cannot reliably guide, such as inserting connectors, threading components, handling fragile laboratory equipment and performing fine alignment operations in electronics assembly.

Teleoperation and Data Collection

With zero torque and teaching modes, the Revo 3 supports teleoperation rigs and human demonstration capture, generating the high quality manipulation trajectories needed to train modern robot foundation models.

Advantages and Benefits

• Class leading dexterity. 21 active degrees of freedom with full five finger opposition and 33 grasp types.
• Sensing where it matters. Full palm tactile coverage at 0.01 N resolution plus 130 μm visuotactile fingertip perception.
• True force control. Direct drive backdrivable joints deliver compliance and safety without sacrificing 20 N pinch strength.

Frequently Asked Questions

What is the BrainCo Revo 3?

The BrainCo Revo 3 is a full size, five finger dexterous robotic hand with 21 active degrees of freedom, released in April 2026. It combines direct drive backdrivable joints with full palm tactile sensing and fingertip visuotactile perception, making it one of the most capable robotic hands available for humanoid robots and embodied AI research.

How does the BrainCo Revo 3 work?

The Revo 3 uses direct drive motors at every joint, controlled at 500 Hz across position, force position, admittance and zero torque modes. Its tactile array measures contact forces at 0.01 N resolution across the palm, while optical visuotactile sensors in each fingertip detect surface deformation down to roughly 130 μm, allowing the hand to feel and adjust its grip in real time.

Why is the BrainCo Revo 3 important?

The Revo 3 addresses the biggest limitation of previous robotic hands: tactile blindness. By moving high resolution touch sensing inside the hand, it enables stable in-hand manipulation, slip detection and delicate handling that camera guided systems cannot achieve, marking a significant step toward human level robot dexterity.

What are the benefits of the BrainCo Revo 3?

Key benefits include 21 degrees of freedom with full thumb opposition, over 70 N grasping force with fine 20 N pinch control, a 20 kg payload, 33 grasp types, industrial EtherCAT and CAN FD connectivity, an open ROS 2 software ecosystem and dual layer tactile sensing unmatched in its class.

What is the difference between Revo 3 Basic, Touch and Vision?

All three share the same 21 DOF mechanical platform. The Basic configuration omits tactile sensors, the Touch adds the full palm tactile array, and the Vision (V-Touch) configuration adds fingertip visuotactile sensing on top of palm sensing for maximum perceptual depth in precision manipulation tasks.

What robots is the Revo 3 compatible with?

The Revo 3 is designed for integration with humanoid robots, collaborative robot arms and custom research platforms. Its EtherCAT, CAN FD and RS-485 interfaces, 12–80V input range and ROS 2 driver support allow it to connect to most modern robotics control architectures.

Where can I buy the BrainCo Revo 3 and what does it cost?

The BrainCo Revo 3 is available for sale through authorized distribution channels serving international markets.
