BrainCo Revo 2

BrainCo Revo 2

The BrainCo Revo 2 is an intelligent bionic dexterous hand developed by BrainCo, a leading brain computer interface and robotics company headquartered in Hangzhou, China, with operations near Boston, Massachusetts. Unveiled in September 2025, the Revo 2 builds directly on BrainCo's years of experience producing neural controlled prosthetic hands for people with limb differences, carrying that mature, life tested engineering into the rapidly growing market for humanoid robot end effectors.

The Revo 2's defining achievement is its balance of weight and strength. At just 383 grams, it delivers a 50 N power grasp and supports a static load of up to 20 kg, giving it a grip to weight ratio of 52.6, which BrainCo cites as best in class. This "millimeter level subtraction" engineering philosophy, refining bionic joints, transmission mechanisms and system integration until nothing unnecessary remains, produced a hand that mimics human anatomy both structurally and functionally while remaining light enough for any humanoid arm.

Offered in three configurations, the Revo 2 Basic, Revo 2 Pro and Revo 2 Touch, the platform scales from affordable research prototyping to industrial integration and advanced tactile manipulation. For robotics teams evaluating a proven, mass produced bionic hand for sale, the Revo 2 is one of the most widely deployed dexterous hands of its generation.

Design and Features

Bionic Anatomy at Human Scale

The Revo 2 measures 160 mm from middle fingertip to palm base and 76 mm across the palm, matching adult human hand proportions. It is built from aerospace grade aluminum alloy and food grade plastic, finished in Space Black or Silver with color customization available. The hand provides 11 total degrees of freedom driven by 6 precision motors: the thumb offers two active degrees of freedom for abduction and adduction plus a passive flexion joint, while each of the four fingers combines one active and one passive flexion degree of freedom for natural, coupled curling motion.

Strength Without Weight

Despite its 383 g mass, the Revo 2 produces a 50 N active grasping force, a 15 N fingertip pinch and a 20 kg static load capacity. Fingers open and close in 0.65 seconds with 0.1° repeat accuracy, and operating noise stays below 50 decibels, quieter than typical office background sound. The hand remains fully functional while wearing professional work gloves, including anti puncture gloves, preserving flexibility in industrial and laboratory settings.

Turbo Mode and Intelligent Protection

For applications demanding an unbreakable hold, Turbo mode actively re grips every 500 milliseconds, maintaining sustained clamping force on carried objects. Built in protections guard against overcurrent, overvoltage, high temperature, stall and collision conditions, while automatic position calibration at power on ensures consistent control from the first command.

Multimodal Tactile Perception

The Revo 2 Touch variant adds BrainCo's multimodal tactile sensing system, measuring pressure, friction, force direction and proximity with force resolution of 0.1 N and down to 0.01 N at maximum sensitivity. This lets the hand assess an object's hardness and texture and perform genuinely delicate feats, BrainCo has demonstrated the Revo 2 striking a match, a task requiring precisely modulated force and real time tactile feedback.

Technology and Specifications

Core Specifications

Control Architecture

The Revo 2 supports position, speed and current control across all variants, with adaptive impedance control on the Pro and adaptive compliance plus adaptive tactile control on the Touch. Communication runs at up to 1 kHz, enabling high speed closed loop servo control for responsive, real time manipulation. Left and right hand units ship with distinct default IDs and can be reassigned freely for multi hand and dual arm installations.

Variant Lineup

• Revo 2 Basic. RS-485 and CAN FD communication with 9–28V operation. The entry point for research prototyping and education.
• Revo 2 Pro. Adds EtherCAT and a 9–64V wide voltage range with adaptive impedance control, built for industrial integration and high performance research.
• Revo 2 Touch. The full platform with EtherCAT, wide voltage support and multimodal tactile perception for advanced manipulation and haptics research.

Software and Development

BrainCo provides a complete SDK package with C++ and Python support for Linux and Windows, ROS 2 drivers, robot description assets, simulation resources and custom gesture definition. Over the air firmware updates keep deployed hands current throughout their service life, and secondary programming support allows deep customization for application specific behavior.

Applications and Use Cases

Humanoid Robotics

The Revo 2's featherweight construction makes it ideal as a five finger end effector for humanoid platforms, where every gram at the wrist multiplies torque demands up the arm. Its human matched dimensions allow robots to use tools, handles and objects designed for people.

Embodied AI Research

Universities and laboratories use the Revo 2 to develop manipulation policies, study grasp planning and collect demonstration data. The Touch variant's tactile stream adds contact rich sensing for machine learning research in slip detection and force aware control.

Industrial and Service Automation

With EtherCAT connectivity, glove compatibility, quiet operation and intelligent protection systems, the Pro and Touch variants integrate into production lines, laboratory automation and service robotics where reliability and mass production quality matter.

Prosthetics Derived Reliability

Because the Revo 2 descends from BrainCo's clinically deployed prosthetic hands, its mechanisms have been proven through years of daily human use, from rock climbing to piano playing, a durability pedigree few robotics first competitors can match.
