Brainco Revo 2 Touch Biomimetic Dexterous Right Hand (XTR)

A gripper opens and closes. A hand has to decide how hard to hold, when to slip and when to let go. The Brainco Revo 2 Touch Biomimetic Dexterous Right Hand (XTR) belongs to the second group: a bionic hand for robot integration and research, and the touch-oriented version of the Revo 2 family, built for work where holding something is only half the problem.

Robots USA sells the Brainco Revo 2 Touch Right Hand (XTR) and supplies it to robotics labs, integrators and humanoid developers across the United States. Robots USA prepares your quotation, arranges delivery and supports the hand after it ships.

Background

Brainco and the Revo line

Brainco was founded in 2015 and incubated by the Harvard Innovation Lab (i-Lab). The company works on the boundary between the human body and machines, and the Revo hands are among its products for robotics and research. The Revo 2 generation comes in three versions: Basic (XRL/XRR), Pro (XEL/XER) and Touch (XTL/XTR). The last letter of each code gives the side, so XTR is the right-hand Touch model and XTL is its left-hand twin.

Where the Touch version sits

Revo 2 is described by its source as a bionic dexterous hand with 6 active joints and a total of 11 degrees of freedom. That is a compact actuation scheme with a large range of finger and thumb postures, and it is the kind of layout researchers choose when a one-motion gripper is too limiting. The Touch version carries the tactile designation within the family. The tactile sensor resolution has not been published by any source, so exact sensing figures are confirmed at quotation. Mechanically and electrically it is a right-hand hand with a 12-64V supply range, closed-loop servo control and a set of built-in protections.

Technical Specifications

Specifications as published by a single source; they are confirmed against the manufacturer's datasheet at quotation.

What makes the Touch version different from Basic and Pro?

All three versions share the Revo 2 platform, and the published material describes the family as one design with different capabilities. The clearest difference on the record is electrical. The published supply voltage for the Touch version is 12-64V. The Basic version is listed at 12-28V, while the Pro version is listed at 12-64V, the same as Touch. If your robot runs on a higher-voltage bus, the Basic hand is the one that narrows your options. If you do not need tactile perception, the Pro right hand (XER) or the Basic right hand (XRR) may be the better fit.

The Touch designation is where this hand earns its place. A hand that can report on contact is useful for tasks where force and slip matter more than raw reach: handling fragile parts, learning grasp policies, or testing haptic feedback loops. The manufacturer has not published the tactile sensor resolution, so we do not quote a sensor figure here. If tactile data is the point of your project, ask for it when you request the quotation and compare it with your requirements before you commit.

How is the hand controlled and protected?

Revo 2 uses closed-loop servo control, so the hand works against feedback rather than open-loop commands. Its published control precision is 0.1°, and its published pinch force is at least 15N. Custom gesture definitions let you store and recall hand postures instead of rebuilding them in every program.

Protection matters just as much in a lab as on a production floor, because research hardware gets driven hard. The published specification lists protections for current, stall, high temperature and collision conditions. In practice that means the hand has defined responses when a motor draws too much current, a finger is blocked, the unit heats up or it strikes something.

On the integration side, the hand supports RS485, CAN FD and EtherCAT communication interfaces. SDK support covers Linux, Windows and ROS workflows, so it fits a ROS-based humanoid stack as readily as a Windows lab bench. For multi-hand systems, the default device ID is 127 for the right hand, and the left hand uses a different default ID, so a pair can share a bus without a conflict on delivery.

Who is the Brainco Revo 2 Touch Right Hand (XTR) for?

Humanoid developers are the obvious buyers. A right hand with a compact actuation layout and standard industrial buses is easier to fit to an arm than a custom build. Pair it with the Touch left hand (XTL) and you have a matched set.

University and corporate research groups are the second segment. Dexterous manipulation, tactile learning and teleoperation studies all need a hand that exposes its control stack and has a documented SDK. Browse our Research Robots category if you are still choosing the platform the hand will sit on.

Integrators who build demonstration cells or pilot lines form the third group. They benefit from EtherCAT and CAN FD, which sit naturally in industrial controllers. If you only need a less costly entry into the Revo 2 family and tactile data is not on your list, look at the Basic or Pro versions instead. For other options, see the full Hands category.

What is the Brainco Revo 2 Touch Right Hand (XTR) used for?

1. Humanoid robot integration. Gives the right arm of a humanoid a hand with 11 degrees of freedom.
2. Dexterous manipulation research. Supports studies of in-hand motion, grasp planning and learning-based control.
3. Tactile-aware grasping. Suits experiments where contact information should shape the grip.
4. Teleoperation development. Custom gesture definitions and a scripted SDK help map operator input to hand postures.
5. Industrial R&D cells. RS485, CAN FD and EtherCAT let the hand connect to existing controllers.
6. Teaching and demonstration. A documented SDK for Linux, Windows and ROS suits lab courses and showcase rigs.

Pricing and Availability

Robots USA does not list a fixed price for this hand because configuration, quantity and project scope shape the offer.

Frequently Asked Questions

How many joints and degrees of freedom does the Revo 2 Touch have?

The published specification lists 6 active joints and a total of 11 degrees of freedom for the Revo 2 hand.

Which communication interfaces does it support?

It supports RS485, CAN FD and EtherCAT. The SDK covers Linux, Windows and ROS workflows, per the published specification.

What protections are built in?

The published specification lists protections for current, stall, high temperature and collision conditions, alongside closed-loop servo control.

What supply voltage does the Touch version use?

The Touch version is listed at 12-64V. The figure is reported by a single source and is confirmed against the datasheet at quotation.

What is the default device ID of the right hand?

The default ID for the right hand is 127. The left hand has a different default ID, so a matched pair can share a bus.

Is the ingress protection rating published?

No. The ingress protection rating, the Touch operating temperature, the tactile sensor resolution and the box contents have not been published, so we confirm them at quotation.

Where can I buy the Brainco Revo 2 Touch Right Hand (XTR) and what does it cost?

Robots USA sells and supplies it. We quote on request, so there is no price on the page. Send us your requirements and we will respond with a quotation.

Summary

The question behind this hand is whether you want a gripper that is easy to wire or a hand that is rich in motion. The Brainco Revo 2 Touch Right Hand (XTR) is built to avoid that choice: 6 active joints, 11 degrees of freedom, closed-loop control, RS485, CAN FD and EtherCAT, a 12-64V supply and a tactile orientation. Several details, including sensor resolution, ingress protection and box contents, are unpublished and confirmed at quotation. If you are planning a humanoid build or a manipulation study and want Robots USA to quote, deliver and support it, this page is the starting point.
