BrainCo Revo 2 Basic Left Dexterous Bionic Hand (XRL)

A convincing grasp is not enough: a robotics project also needs a hand that fits its electrical architecture, control software, and test plan. The BrainCo Revo 2 Basic Left Dexterous Bionic Hand (XRL) is described in the published specification as a bionic dexterous hand for robot integration and research. For buyers, the useful starting point is therefore not appearance alone, but the relationship between its reported actuation, communication interfaces, and integration requirements.

Robots USA sells this product for robotics projects in the United States. Robots USA handles the quotation and coordinates delivery and support arrangements around the proposed application. Identify the left-hand configuration, intended controller, and mechanical mounting requirements when requesting a quotation so that the supplied configuration and documentation can be checked before purchase.

Background

BRAINCO and the documented Revo family

This product is identified under the BRAINCO brand. The published version information names Basic (XRL/XRR), Pro (XEL/XER), and Touch (XTL/XTR), giving buyers a way to distinguish configurations within the Revo 2 family. The available product evidence does not establish a detailed company history or a documented engineering lineage from earlier hands. Selection should rest on the published configuration data rather than assumptions about inherited technology.

Version identification matters throughout procurement. A family name can cover different electrical requirements, and a left-hand designation should remain explicit in drawings, software configuration, and the quotation. Treat the model code as part of the integration record, not merely a catalog label.

Basic positioning and control architecture

According to the published specification, the Basic version communicates through RS-485 or CAN FD and provides position, velocity, and current feedback control, together with cascaded control and compliance control. These are relevant capabilities for teams developing manipulation software, but they do not by themselves establish how a particular grasp will perform on a particular object.

The published specification also reports an SDK supporting Python/C and compatibility with Linux/Windows/ROS systems. That is a useful starting point for software planning. The exact SDK release, command definitions, dependencies, and examples should be reviewed against the project's controller environment before an integration commitment is made.

Technical Specifications

These specifications are reported as published and are confirmed against the datasheet at quotation.

What should you check before integrating the Basic Left hand?

Start with power and communication rather than a demonstration grasp. Per the published specification, Basic uses a 12-28V supply and an interface located under the wrist with connector model BM05B-PASS-TFT(LF)(SN). The connector reference does not establish the complete wiring arrangement, mating components, or cable supplied. Request those details before finalizing a harness or wrist adapter.

The manufacturer has not published the width, materials, or cable length in the available sources; these are confirmed at quotation. Consequently, the reported height is not enough to establish clearance around the palm or wrist. Mechanical fit should be checked using the relevant drawings, with room for wiring and the intended range of motion.

Per the published specification, the hand includes current, stall, high-temperature, and anti-collision protection. These functions should be understood within the controller documentation, not treated as evidence of a certified safety system. The manufacturer has not published an IP rating in the available sources; it is confirmed at quotation, so environmental suitability remains an explicit review item.

How should you interpret the grip and payload specifications?

The published specification reports full fist grip force of ≥50N, pinch force of ≥15N, and max payload of ≥20kg. These entries describe different aspects of performance and should not be treated as interchangeable guarantees. A payload entry does not establish that every object can be held securely in every orientation or manipulation sequence.

For a useful acceptance test, define the object surface, grasp geometry, motion, and failure criteria. The published information does not provide the test conditions behind these force and payload entries. Ask Robots USA to confirm the supporting datasheet information at quotation, then assess whether those conditions represent the proposed task.

Per the published specification, the hand has 11（6 active） degrees of freedom. This distinguishes the reported total articulation from the active joints; it should not be interpreted as independent control of every degree of freedom. Review the joint mapping before designing trajectories or comparing manipulation strategies.

Who is BrainCo Revo 2 Basic Left Dexterous Bionic Hand (XRL) for?

This configuration is relevant to robotics laboratories, university research groups, and integration teams evaluating left-hand manipulation. The published SDK and interface information provide a basis for assessing software fit, while the unresolved mechanical and environmental details make a documentation review essential. Buyers comparing the broader Hands category should use the same task-specific criteria across candidates.

If a project instead requires a right-hand configuration, review the BrainCo Revo 2 Basic Right Dexterous Bionic Hand (XRR). For buyers whose power architecture requires the wider reported 12-64V supply range of Pro, the BrainCo Revo 2 Pro Dexterous Left Hand (XEL) is worth evaluating. That voltage difference alone does not establish superiority for a manipulation task, and Pro specifications must not be substituted for Basic figures.

What is BrainCo Revo 2 Basic Left Dexterous Bionic Hand (XRL) used for?

1. Grasp planning research: Evaluate candidate hand postures against defined objects and success criteria.
2. Robot integration studies: Assess mechanical, electrical, and software requirements before committing to a system design.
3. Control development: Investigate command and feedback workflows using the supported control functions.
4. Bimanual experimentation: Study left-hand roles within a separately validated coordinated manipulation setup.
5. Teaching laboratories: Explore the relationship between articulation, grasp geometry, and controller behavior.
6. Application feasibility testing: Determine whether a proposed handling task merits further engineering and validation.

Frequently Asked Questions

Is this the Basic left-hand configuration?

Yes, this page identifies the product as Basic Left (XRL). The published version listing reports XRL/XRR for Basic, distinct from the Pro and Touch codes.

Can the Basic hand use RS-485 or CAN FD?

According to the published specification, Basic can communicate and be controlled through RS-485 or CAN FD. Confirm the interface implementation, wiring, and controller requirements at quotation.

Does the SDK support ROS?

The published specification reports Python/C SDK support and compatibility with Linux/Windows/ROS systems. Specific ROS distributions and software versions are not established by the available information.

Are all degrees of freedom independently actuated?

The published specification reports 11（6 active） degrees of freedom. It does not support treating every degree of freedom as independently actuated.

What default device ID does the left hand use?

Per the published specification, the left hand has default device ID 126. Verify the configuration before connecting it to a shared communication bus.

Are cables and mounting parts included?

The manufacturer has not published package contents or cable length in the available sources; these are confirmed at quotation. Do not assume that a cable, adapter, or mounting hardware is included.

Where can I buy BrainCo Revo 2 Basic Left Dexterous Bionic Hand (XRL) and what does it cost?

Summary

The decision comes back to the gap between a convincing grasp and a well-integrated system. The reported Basic Left control, communication, and SDK features offer a basis for evaluation, while mechanical details, performance test conditions, and package contents still require confirmation. For a quotation built around those checks rather than assumptions, this page is the starting point.
