BrainCo Revo 2 Basic Right Dexterous Bionic Hand (XRR)

A humanoid robot has two hands, and they are not interchangeable. Each one has to be ordered, wired, addressed and tested on its own side of the body. The BrainCo Revo 2 Basic Right Dexterous Bionic Hand (XRR) is the right-hand member of the Basic line: a bionic dexterous hand that its published source describes as made for robot integration and research. This article sets out what that source supports, and says plainly where it is silent.

Robots Latin America sells this hand and supplies it to integrators, laboratories and universities across Latin America. We prepare the quotation, arrange delivery and customs with it, and support the order afterwards, in a formal yet friendly way, so that your team always knows who is answering its questions.

Background

BrainCo and the Revo 2 family

BrainCo is the brand behind the Revo 2 range of bionic dexterous hands. The sources we hold name three versions of Revo 2: Basic, Pro and Touch. Each is sold as a left and a right hand, and each carries its own version code. The Basic hand is coded XRL for the left and XRR for the right. The Pro hand is coded XEL and XER, and the Touch hand XTL and XTR. For a buyer this coding matters more than it may seem, because a purchase order that names only the family can easily end up with the wrong hand or the wrong side.

The fact sheet for this product does not describe the company's history or the technical lineage of the range, so we do not invent one here. Teams that want that background should request it from the manufacturer's documentation at quotation. The Revo 2 range has its own page in our catalog under BrainCo Revo 2.

Positioning of the Basic right hand

The Basic version is the entry point of the Revo 2 family. Within it, the XRR is the right-handed unit. The published specification gives it 11 degrees of freedom, of which 6 are active. In plain terms, the hand has more joints than it has independently driven axes. That is a common arrangement in multi-finger hands: some joints move together with those that are driven. The source does not say how the coupling is arranged, so teams that need to model finger kinematics should ask for the detailed documentation before they plan their control software.

The same source places the communication connector under the wrist. The connector model is BM05B-PASS-TFT(LF)(SN). It also states a default device ID, 127 for the right hand and 126 for the left. These details are small, but they decide how quickly a hand goes from the shipping box to a working bench setup.

Technical Specifications

Specifications as published by a single source; they are confirmed against the manufacturer's datasheet at quotation, and the manufacturer has not published the four items marked above.

What should an integrator check before ordering the XRR?

Start with the items the manufacturer has not published. The ingress protection rating is the first: without it, we cannot say whether the hand may be used in dusty, humid or washdown settings, so it should be treated as a laboratory or protected-environment component until the datasheet says otherwise. The dimensions with the wrist are the second. They decide whether the hand fits the flange of your arm and the envelope of your humanoid forearm, so mechanical designers should request the drawing at quotation. The third is the flexion/extension lifespan, which matters for any project that expects many grasp cycles in a test campaign. The fourth is the battery: the source gives no battery information, so a buyer should not assume the hand carries its own power, and should ask how it is supplied.

Next, the electrical and software side. The connector sits under the wrist, which is helpful for cable routing along a forearm. Since the connector designation is given, a harness can be prepared in advance, but we advise confirming the pinout in the datasheet first. The default device ID of 127 for the right hand means that, when a left and a right hand share one communication bus in a bimanual system, they already start with different addresses, 126 and 127. This reduces the risk of a conflict on first power-up. It does not remove the need to check how the ID is changed if your system uses a different addressing scheme.

What separates the Basic hand from the Pro and Touch versions?

The sources confirm that the Revo 2 family has three versions, but the fact sheet for this product gives figures only for the Basic hand. We therefore do not attribute any figure to the Pro or the Touch hands, and we do not describe what they add beyond what their names and codes suggest. The name of the Touch version points to a tactile focus, but its specifications are not stated here. A buyer who needs feedback from the fingertips or surface should compare the datasheets of the versions at quotation rather than rely on a name.

If your project needs a different version, the catalog lists them separately: the BrainCo Revo 2 Pro Dexterous Right Hand and the Brainco Revo 2 Touch Biomimetic Dexterous Right Hand (XTR). Our team will explain the differences once the manufacturer's documents are in hand.

Who is the BrainCo Revo 2 Basic Right Dexterous Bionic Hand (XRR) for?

The first group is robotics research laboratories and university teams. They often build manipulation experiments on arms that came with a simple gripper, and a hand with several active axes gives them a way to study grasping strategies that a gripper cannot reproduce. The second group is humanoid developers. A humanoid needs a hand on each side, and the right-hand XRR pairs with the BrainCo Revo 2 Basic Dexterous Bionic Left Hand (XRL), so that a bimanual platform can be completed from one family with matching codes.

The third group is system integrators who prototype manipulation cells for clients and want a documented connector and a predictable device address to shorten commissioning. The fourth is engineering teams that do not yet know how much hand their project needs. For them, the Basic version is a sensible place to begin, and the other versions are there if the first results call for more. Teams that expect to work in wet or dusty conditions, or that need long-cycle durability data, should wait for the datasheet before committing, because those figures are not published. The wider Hands category shows other options.

What is the BrainCo Revo 2 Basic Right Dexterous Bionic Hand (XRR) used for?

1. Robot arm end effector: it replaces a simple gripper with a multi-joint hand on a research or prototype arm.
2. Humanoid right hand: it supplies the right side of a two-handed platform, together with the matching left-hand unit.
3. Manipulation research: it lets laboratories test grasp planning and control on a hand with six active axes.
4. Integration prototyping: it helps integrators prove a handling concept before they design a production cell.
5. Teaching and demonstration: it gives students and visitors a physical example of dexterous robotic manipulation.
6. Communication and control development: it provides a documented connector and a default device ID on which software teams can build drivers.

It is the right hand, with version code XRR. The matching Basic left hand carries the code XRL.

How many degrees of freedom does it have?

The published specification gives 11 degrees of freedom, 6 of them active. The source does not explain how the passive joints are coupled, so we confirm that detail against the datasheet at quotation.

Where is the communication connector?

Per the published specification, the interface is located under the wrist, and the connector model is BM05B-PASS-TFT(LF)(SN).

What is the default device ID?

The source states a default ID of 127 for the right hand and 126 for the left hand. Please confirm how it is changed if your system uses other addresses.

Is the hand waterproof or dust-resistant?

The manufacturer has not published an IP rating, so we cannot make any such claim. It is confirmed at quotation.

Does the source give the size or battery information?

No. Dimensions with the wrist, the flexion/extension lifespan and battery details are all unpublished, and we request them from the manufacturer at quotation.

Where can I buy the BrainCo Revo 2 Basic Right Dexterous Bionic Hand (XRR) and what does it cost?

Summary

A pair of hands is only as good as each hand's place in the system, and the XRR is the right-hand piece of the Basic line. It offers 11 degrees of freedom with 6 active, a documented connector under the wrist and a default right-hand device ID of 127, all as reported by a single published source. What it does not yet offer is a full set of published figures, and we have said so rather than fill the gaps. For a quotation tailored to your project, this page is the starting point.
