BrainCo Revo 2 Pro Dexterous Left Hand (XEL)

Two hands rarely do the same job. One steadies the workpiece while the other acts on it, and a robot that treats its left side as an afterthought loses half its usefulness at the bench. The BrainCo Revo 2 Pro Dexterous Left Hand (XEL) is the left-hand unit of the Pro version, a bionic dexterous hand for robot integration and research, with the control, protection and software support that a laboratory expects before it commits a platform.

Robots Europa, based in Dublin, sells this product and supplies it to customers across the EU and the DACH region. Robots Europa prepares the quotation, arranges delivery and handles support enquiries, so a single contact covers the whole purchase from the first technical question to the arrival of the hand.

Background

BrainCo and the Revo 2 family

BrainCo is the brand behind the Revo 2, a bionic dexterous hand developed for robot integration and research. The family is sold in three versions, and the version code is the quickest way to tell them apart. The Basic version carries the codes XRL and XRR, the Pro version carries XEL and XER, and the Touch version carries XTL and XTR. In each pair the final letter distinguishes the left hand from the right.

This page covers the Pro left hand, XEL. If your project needs the right-hand counterpart, the BrainCo Revo 2 Pro Dexterous Right Hand (XER) is the matching unit. The whole range can be browsed in the BrainCo Revo 2 category, and further hands are collected under Lámha.

Positioning and key technology

The Revo 2 is built around 6 active joints that together provide a total of 11 degrees of freedom. That difference between actuated joints and total freedom is typical of dexterous hands, where some finger motion is coupled to the motion of an active joint instead of having a motor of its own. The result is a hand that can form a range of grasps without requiring one actuator for every degree of freedom.

Control is closed-loop servo control, with custom gesture definitions so that a team can define the hand postures its own experiment needs. Protection is built in as well: the hand includes current protection, stall protection, high-temperature protection and anti-collision protection. For anyone who has watched a prototype gripper stall against a fixture, protections of this kind are a practical consideration, not a decoration. On the software side, the SDK supports Linux, Windows and ROS workflows, which covers the environments most robotics groups already work in.

Technical Specifications

Specifications as published by the manufacturer; confirmed against the datasheet at quotation.

The manufacturer has not published the weight of the Pro version, the IP rating, the contents of the box, the cable length or the certifications; they are confirmed at quotation.

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

The three versions share the Revo 2 name and the same purpose, but they are separate products with their own codes, and the specifications of one should not be assumed for another. The Pro version is identified by XEL and XER.

If you want to compare, the Basic left hand is the BrainCo Revo 2 Basic Left Dexterous Bionic Hand (XRL), and the Touch left hand is the Brainco Revo 2 Touch Biomimetic Dexterous Left Hand (XTL). Weigh the three against your own requirements for force, feedback and integration rather than against each other in the abstract.

Why does a left hand deserve its own consideration?

Many research projects begin with a single hand and later grow into a bimanual setup. Ordering the correct side from the start avoids a mismatch later: a left hand is not interchangeable with a right one, and the codes XEL and XER exist for exactly that reason. Bimanual tasks such as holding a container while the other hand opens it, passing an object between hands, or fixing a part while a tool is applied all depend on both sides being specified with equal care.

When you request a quotation, state the side explicitly, the robot platform that will carry the hand, and the software environment you will use. That lets the outstanding details be checked before an order is agreed.

Who is the BrainCo Revo 2 Pro Dexterous Left Hand (XEL) for?

The first group is university and institute laboratories studying grasping, in-hand manipulation and learning from demonstration. For them, a hand with a documented SDK for Linux, Windows and ROS reduces the time spent on software plumbing, and custom gesture definitions let students and researchers set up repeatable postures.

The second group is companies building humanoid or dual-arm robot prototypes who need a left-hand unit that can be integrated with their own controller. The closed-loop servo control and the four protections suit a development phase in which mistakes with fixtures, loads and collisions are expected.

The third group is system integrators who evaluate hands for demonstration cells and pilot applications. Colour matters to some of them: the standard colours are Space Gray and Silver, and bulk colour customisation is supported for larger orders.

Buyers who need tactile sensing should look at the Touch version, and those with a simpler specification may prefer the Basic version; both are linked above. For a right-hand position on a Pro platform, choose the XER.

What is the BrainCo Revo 2 Pro Dexterous Left Hand (XEL) used for?

1. Robotics research. Studying grasp strategies and finger coordination with a hand that offers 11 degrees of freedom.
2. Humanoid robot integration. Giving the left arm of a humanoid or dual-arm platform a hand for object handling.
3. Bimanual experiments. Pairing the left hand with a right-hand unit to hold, pass and process objects together.
4. Gesture programming. Defining custom hand postures for repeatable demonstrations and tests.
5. Software development. Building control and perception pipelines against an SDK that supports Linux, Windows and ROS.
6. Teaching and demonstration. Showing students and visitors how a bionic hand is controlled, protected and programmed.

Frequently Asked Questions

Is the XEL a left or a right hand?

It is the left hand. The matching right hand of the Pro version is coded XER.

How many degrees of freedom does it have?

The Revo 2 dexterous hand has 6 active joints and a total of 11 degrees of freedom.

What is the pinch force and the control precision?

The pinch force is ≥15N and the control precision is 0.1°.

Which protections are built in?

The hand includes current protection, stall protection, high-temperature protection and anti-collision protection, together with closed-loop servo control.

Which software environments does it support?

The SDK supports Linux, Windows and ROS workflows. Custom gesture definitions are also available.

Can the colour be chosen?

The standard colours are Space Gray and Silver, and bulk colour customisation is supported. Ask us about quantities when you request a quotation.

Where can I buy the BrainCo Revo 2 Pro Dexterous Left Hand (XEL) and what does it cost?

You can buy it from Robots Europa in Dublin, which supplies customers across the EU and the DACH region. The cost is given in a quotation prepared for your configuration, so please send us your request.

Summary

A robot's left side deserves the same engineering as its right, and the XEL is the Pro version's answer for that side: 6 active joints, 11 degrees of freedom, a pinch force of ≥15N, a control precision of 0.1°, four protections and SDK support for Linux, Windows and ROS.
