BrainCo Revo 2 Pro Dexterous Right Hand (XER)

Most of what decides the fate of a robot hand happens below the wrist, in the cable, the bus and the controller, long before a finger closes on anything. The BrainCo Revo 2 Pro Dexterous Right Hand (XER) is a bionic dexterous hand for robot integration and research, and it rewards the team that thinks about those connections first. Its right-hand configuration, its three communication interfaces and its software support make it a considered component rather than a showpiece.

The product is available through this page, by quotation.

Background

BrainCo and the Revo 2 family

BrainCo is the manufacturer behind the Revo line of bionic hands. The Revo 2 is the second generation, a bionic dexterous hand for robot integration and research. The series is organised in three versions: Basic (XRL/XRR), Pro (XEL/XER) and Touch (XTL/XTR). The final letter of each code indicates the side: L for left and R for right.

The listing on this page is the Pro version in its right-hand configuration, coded XER. Its left-hand counterpart is the BrainCo Revo 2 Pro Dexterous Left Hand (XEL). Institutions assembling a pair for a bimanual platform will normally request both sides in a single quotation. The wider range can be browsed in the BrainCo Revo 2 category.

Positioning and key technology

The Revo 2 series offers 6 active joints and 11 degrees of freedom. The thumb has two active degrees of freedom for abduction and adduction, and one passive degree of freedom for flexion and extension. Each of the remaining four fingers has one active and one passive degree of freedom for flexion and extension. In practical terms, the hand couples a small number of actuated joints with passive joints that complete the finger motion.

Control is closed-loop servo control, and the hand allows custom gesture definitions, so that a research group can store the postures its experiments call for. The hand also carries protections for current, stall, high temperature and collision conditions. For a laboratory where trials are repeated many times and occasionally go wrong, such safeguards matter as much as the range of motion.

On the software side, the series provides SDK support for Linux, Windows and ROS workflows. The Pro version supports three communication interfaces, RS485, CAN FD and EtherCAT, with the interface located below the wrist. Teams can therefore match the hand to the bus architecture of the platform instead of rebuilding the platform around the hand.

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

The three versions share the same architecture: 6 active joints, 11 degrees of freedom, the same thumb and finger layout, and the same SDK support. The difference that matters for integration is the control bus. The Pro, like the Touch, supports three communication interfaces: RS485, CAN FD and EtherCAT. That is the practical argument for the Pro. A team whose robot uses an EtherCAT master, or a CAN FD network, can connect the hand directly without a translation layer.

Buyers who want to compare the neighbouring versions can view the BrainCo Revo 2 Basic Right Dexterous Bionic Hand (XRR) and the Brainco Revo 2 Touch Biomimetic Dexterous Right Hand (XTR). Requesting them in the same quotation allows a side-by-side comparison for your platform.

How does the hand suit a research workflow?

A research hand is judged by how quickly it becomes part of the experiment. Here the software support is the first answer: SDK support for Linux, Windows and ROS workflows means that groups working in ROS, and those working on Windows workstations, can both begin without writing a driver from scratch. Custom gesture definitions allow repeatable postures to be stored and called on demand, which helps when a study compares many control strategies against the same set of grasps.

The second answer is protection. Current, stall, high temperature and collision protections reduce the risk that an unsuccessful trial damages the hand. In a shared laboratory, where several students may operate the same equipment, that margin is valuable. The closed-loop servo control completes the picture by letting the controller command and monitor finger motion as part of a feedback loop.

Who is the BrainCo Revo 2 Pro Dexterous Right Hand (XER) for?

The first segment is the humanoid developer who needs a right-hand end-effector with a bus that matches the rest of the robot. The second is the university or institute laboratory studying grasping, teleoperation or learning-based manipulation, where the ROS and Linux support shortens the setup. The third is the integrator fitting a hand to a manipulator for demonstration or pilot work, who values the built-in protections.

Teams building a two-handed robot should pair this unit with the left-hand Pro version. Those whose controller does not require the Pro interfaces may wish to look at the Basic right-hand version. Wider options are listed in the Hands category.

What is the BrainCo Revo 2 Pro Dexterous Right Hand (XER) used for?

1. Humanoid robot integration. Fitted to the right wrist of a humanoid platform as its manipulation hand.
2. Manipulation research. Studying grasp strategies with a hand of 6 active joints and 11 degrees of freedom.
3. Control development. Tuning servo and bus behaviour over RS485, CAN FD or EtherCAT.
4. Gesture programming. Defining and repeating custom gestures for experiments and demonstrations.
5. Software prototyping. Building applications through the SDK on Linux, Windows or ROS.
6. Teaching and training. Giving students a protected, real bionic hand on which to practise robot control.

Summary

The decisive qualities of this hand are found below the wrist and in the software: three communication interfaces, SDK support for Linux, Windows and ROS, and a set of protections that suit repeated trials. Add 6 active joints and 11 degrees of freedom, and the BrainCo Revo 2 Pro Dexterous Right Hand (XER) is a hand designed to be integrated, not merely admired.
