BrainCo Revo 2 Basic Dexterous Bionic Hand (XRL/XRR)

BrainCo Revo 2 Basic Dexterous Hand

BrainCo's intelligent bionic dexterous hand Revo 2 is based on the mature technology iteration and upgrade of prosthetic hands and the Revo 1 dexterous hand, continuing the stability and high performance advantages of its predecessor. The Revo 2 dexterous hand is equipped with 6 motors, has 6 active joints, and a total of 11 degrees of freedom. It weighs 383g, has a size of 160mm, an active gripping force of 50N, and a maximum load of 20kg, achieving an extreme load while being lightweight and compact, with a bionic and aesthetic appearance. The Revo 2 dexterous hand can be equipped with multi-dimensional tactile perception capabilities, is industry-leading in stable mass production, and is reliable in quality. It supports multiple communication protocols including 485, CANfd, and EtherCAT, with a maximum communication support of 1KHz, enabling high-speed real-time communication. It supports SDK, is compatible with Linux, Windows, and ROS, and supports high-speed secondary development. It features customizable gestures, multiple protections, servo control algorithms, tactile adaptive gripping, OTA online upgrades, and more, facilitating the rapid implementation of dexterous scenarios.

Parameter description

Degree of freedom distribution

The Revo 2 dexterous hand has 6 active joints and a total of 11 degrees of freedom. The thumb has two active degrees of freedom for abduction and adduction, as well as one passive degree of freedom for flexion and extension, while each of the remaining four fingers has one active degree of freedom for flexion and extension and one passive degree of freedom for flexion and extension.

Turbo Mode Description

Turbo mode is implemented based on the stall function. After the motor stalls for a certain period (stall time), it resumes movement, periodically executing stop and continue motion. In specific situations where reliable gripping is required, we provide Turbo mode, where every 500ms, the fingers actively grip to achieve a sustained and reliable gripping force.

Device ID description

For Revo 2, default ID for the left hand is 126, and for the right hand, it is 127. Users can modify them within the range of 1 - 254.

Description of the power-on self-reset mode

The automatic reset upon powering on refers to the dexterous hand automatically executing position calibration after being powered on. Upon startup, the dexterous hand will search for the starting position of the fingers, during which all fingers will be activated.

Note 1: During the position calibration process, if the dexterous hand is gripping an object, there may be a risk of dropping it.

Note 2: After the dexterous hand is powered on, position calibration must be performed once to enable normal control.

Communication interface description

Revo 2 Basic

The basic version of the second-generation hand can communicate and control via the 485 or CAN FD communication interface. The interface is located under the wrist, and the connector model is BM05B-PASS-TFT(LF)(SN)。

Revo 2 Pro&Touch

The second generation hand advanced version and tactile version support three communication interfaces: 485/CAN FD/EtherCAT for communication and control, with the interface located below the wrist.
