Brainco Revo 2 Touch Biomimetic Dexterous Left Hand (XTL)

A robotic hand is a conversation between a controller and a set of fingers, and how good that conversation is depends on the wiring and the software as much as on the mechanics. The Brainco Revo 2 Touch Biomimetic Dexterous Left Hand (XTL) is the tactile version of BrainCo's second-generation bionic hand. According to the published specification, it is a bionic dexterous hand for robot integration and research. It is offered here in the left-hand configuration, for teams that need a hand to be commanded precisely and integrated cleanly.

Robots Latin America sells this hand and supplies it to research groups, universities and robotics developers across Latin America. We prepare the quotation, arrange delivery and customs with it, and support the buyer through integration and commissioning questions.

Background

BrainCo and the Revo 2 family

BrainCo is the brand behind the Revo line of bionic hands. The Revo 2 is described in the sources as the second generation, and it is sold in three versions. The Basic version carries the codes XRL and XRR, the Pro version XEL and XER, and the Touch version XTL and XTR. In each pair the first code is the left hand and the second the right hand. This page covers the Touch left hand, XTL.

An earlier hand, the Revo 1, remains in our catalog for buyers who want to compare generations. The Revo 2 family has its own category page, BrainCo Revo 2, and the wider range of dexterous hands is collected under Hands.

Positioning of the Touch version

The Touch version is the tactile member of the family. Per the published specification, the Pro and Touch versions share a communication layout with the interface located below the wrist. The mechanical and control description in the sources is given for the Revo 2 as a whole: 6 active joints and 11 degrees of freedom, with closed-loop servo control. The tactile character of the Touch version is what sets it apart from its siblings. The sources reviewed for this page do not publish details of the tactile sensing itself, such as sensor type, layout or fingertip force resolution. Those details are confirmed at quotation.

Technical Specifications

Specifications as published; confirmed against the datasheet at quotation. The manufacturer has not published the box contents, IP rating, cable length, fingertip force resolution or material in the sources we reviewed, and each of these is confirmed at quotation.

What makes the Touch version different from the Basic and Pro?

The three versions of the Revo 2 share a family description, and the sources name the tactile version as the one built around touch. For a research team the practical difference is the kind of data the hand can return. A hand that only executes a grasp tells you whether the object was lifted. A hand with tactile sensing gives you something to analyze when it was not. How much information the sensing provides, and in what format, is a datasheet question. We confirm it at quotation rather than assume it here.

The communication layout also deserves attention. Per the published specification, the Pro and Touch versions place their interface below the wrist and support RS485, CAN FD and EtherCAT. Buyers who do not need tactile sensing may compare the BrainCo Revo 2 Pro Dexterous Left Hand (XEL) or the BrainCo Revo 2 Basic Dexterous Bionic Left Hand (XRL). Whatever the figures show, each version keeps its own figures, and the pinch force and precision quoted on this page should be checked against the version in the final quotation.

How is the hand controlled and protected?

The published description names closed-loop servo control, which lets the controller read back where each joint actually is rather than only commanding it. Control precision is stated as 0.1°. Custom gesture definitions allow a team to store its own hand postures instead of relying only on preset ones. The hand also lists protections for current, stall, high temperature and collision conditions, which matter on a bench where a program under development may command a finger into an obstacle.

Integration goes through RS485, CAN FD or EtherCAT, with SDK support for Linux, Windows and ROS workflows. For the left hand the default device ID is 126, and the right hand uses 127. In a bimanual setup that detail keeps two hands from answering to the same address on a shared bus. Each of these points rests on the published specification, and we recommend verifying them against the datasheet when the quotation is issued.

Who is the Brainco Revo 2 Touch Left Hand for?

The first group is university and institute laboratories studying grasping, in-hand manipulation and tactile feedback. They need a hand that can be commanded precisely and that supports the usual research software. The second is companies building humanoid or dual-arm platforms and developing hands as part of a prototype. The third is integrators evaluating a dexterous hand for demonstrations or pilot cells, where the choice of fieldbus matters as much as the grip.

The left-hand configuration suits anyone assembling a left arm or the left side of a two-handed system. To build a pair, the mirror version is the Brainco Revo 2 Touch Biomimetic Dexterous Right Hand (XTR). If tactile sensing is not part of the project, the Pro and Basic versions listed above are the simpler comparisons, and our team can help weigh them against your task.

What is the Brainco Revo 2 Touch Left Hand used for?

1. Grasping research. Studying how finger posture, force and contact relate during pick-up and release tasks.
2. Humanoid robot development. Providing the left hand of a humanoid or dual-arm prototype.
3. Tactile feedback experiments. Using the touch version to build and test control strategies that respond to contact.
4. Gesture programming. Defining and replaying custom hand postures for demonstrations or task sequences.
5. Fieldbus integration trials. Testing RS485, CAN FD or EtherCAT control within an existing robot architecture.
6. Teaching and lab training. Giving students a hand to program through the SDK in Linux, Windows or ROS environments.

Frequently Asked Questions

Is this the left or the right hand?

It is the left hand of the Touch version, code XTL. The right-hand counterpart carries the code XTR and is listed separately.

What communication interfaces does it support?

The published specification lists RS485, CAN FD and EtherCAT. The interface is located below the wrist on the Touch version.

Which software environments are supported?

Per the published specification, the SDK supports Linux, Windows and ROS workflows.

What is the default device ID?

The default ID for the left hand is 126, and for the right hand it is 127, according to the published material.

What pinch force and control precision does it offer?

The published figures are a pinch force of at least 15N and a control precision of 0.1°. We confirm both against the datasheet at quotation.

Does it have an IP rating, and what is it made of?

The manufacturer has not published an IP rating or the material in the sources we reviewed. Both are confirmed at quotation, along with the cable length and the box contents.

Where can I buy the Brainco Revo 2 Touch Left Hand and what does it cost?

You can buy it through Robots Latin America, which supplies it across Latin America. The cost is given in a quotation prepared for your project, so no price is listed here.

Summary

The Brainco Revo 2 Touch Left Hand is a hand to be talked to as much as watched. Its published strengths are fine control, multiple fieldbus options, SDK support for common research environments, protective functions and a tactile version aimed at those who want to study touch. The details a buyer will still want, such as sensing specifics, IP rating and material, are unpublished and are confirmed at quotation. For teams ready to put the hand on a bench, Robots Latin America quotes, delivers and supports it, and this page is the starting point.
