BrainCo Revo 3-21 V-Touch Visuotactile Robot Hand

Description

The BrainCo Revo 3-21 V-Touch is a 21-degree-of-freedom dexterous robotic hand that combines a fully direct-drive, backdrivable joint architecture with a dual-layer tactile sensing system integrating full-palm sensing and proprietary fingertip visuotactile technology. The "V-Touch" designation refers to this visuotactile capability: a small embedded camera behind a translucent elastic fingertip membrane captures deformation patterns as the fingertip contacts an object, enabling detection of surface deformation at approximately 130 micrometers while simultaneously using visual input to interpret object geometry and surface properties. BrainCo, founded at Harvard University's Center for Brain Science and holder of more than 360 patents in brain-computer interface and related fields, designed the Revo 3 series to bring prosthetics engineering heritage into commercial robotic end-effectors for humanoid robots and embodied AI platforms.

With 21 degrees of freedom — substantially closer to the human hand's approximate 27 DoF than most competing platforms — the Revo 3-21 V-Touch enables movement patterns including in-hand object rotation, finger gaiting, and tool manipulation. The direct-drive joint architecture eliminates transmission friction, making motor current a direct proxy for contact force across all 21 joints simultaneously. A modular design supports different finger configurations for specific task adaptation, and the hand communicates over EtherCAT, CAN FD, and RS-485 across a 12–80 V supply range, making it compatible with diverse humanoid and industrial robot platforms.

Features

Visuotactile Fingertip Sensing Embedded camera behind a translucent elastic membrane detects object surface deformation at ~130 micrometers, combining touch and vision at the fingertip level.
21 Degrees of Freedom 21 DoF — substantially higher than most competing robotic hands — enables in-hand object rotation, finger gaiting, and natural tool manipulation.
Direct-Drive Backdrivable Joints No gearbox or tendon transmission in any joint: motor current is a direct proxy for contact force, with natural compliance to external forces across all 21 DoF.
Dual-Layer Tactile System Full-palm tactile sensing combined with visuotactile fingertips delivers multi-modal contact awareness from surface to joint level simultaneously.
Modular Finger Configurations Supports different finger configurations to adapt hardware for specific tasks or robotic platforms without replacing the entire end-effector.
Wide Protocol and Voltage Support EtherCAT, CAN FD, and RS-485 communication over 12–80 V input for compatibility with humanoid robots and industrial controllers.

Frequently Asked Questions

What is the price of the BrainCo Revo 3-21?

The BrainCo Revo 3-21 is priced at $35,000 in your market. For volume or project orders, contact us for a business quote.

What is the BrainCo Revo 3-21 V-Touch and what is it designed for?

The Revo 3-21 V-Touch is a 21-DoF dexterous robotic hand designed as an end-effector for humanoid robots and embodied AI platforms. It is built for contact-rich manipulation tasks — including in-hand object rotation, tool use, and delicate grasping — that require both force sensing and surface texture perception.

What does the V-Touch visuotactile system do?

V-Touch refers to BrainCo's proprietary fingertip visuotactile sensing system: an embedded camera behind a translucent elastic membrane captures surface deformation patterns at approximately 130 micrometers as the fingertip contacts objects, combining visual and tactile data simultaneously for superior material and geometry recognition.

What research and industrial applications is the Revo 3-21 V-Touch suited to?

It is particularly suited to embodied AI research, reinforcement learning for manipulation, haptics research, humanoid robot integration, and precision industrial automation where understanding object surface properties during contact is essential for reliable task execution.
