BrainCo Revo 2 Basic Right Dexterous Bionic Hand (XRR)

The BrainCo Revo 2 Basic Right Dexterous Bionic Hand (XRR) is a right-hand intelligent bionic dexterous hand developed by BrainCo as an iteration and upgrade of its mature prosthetic-hand technology and the earlier Revo 1 dexterous hand. The Basic version, identified by the version codes XRL/XRR, is the entry configuration of the Revo 2 family and communicates over RS-485 and CANfd with real-time rates up to 1 kHz, supported by an SDK for Python and C on Linux, Windows, and ROS.

Background

From prosthetic technology to a robotics platform

BrainCo's dexterous hand program is rooted in prosthetic-hand engineering, a domain where reliability, weight, and natural motion are non-negotiable. According to the manufacturer, the Revo 2 is the product of iterating that prosthetic technology together with lessons from the first-generation Revo 1 dexterous hand. This lineage shows in the design priorities: the hand is bionic and aesthetic in appearance, quiet in operation at 50 dB or less measured at 50 cm, and engineered for stable mass production, which BrainCo describes as industry-leading for this product category. The result is a hand intended not as a laboratory prototype but as a repeatable, quality-controlled component that integrators can source in volume.

The Revo 2 family and the Basic configuration

The Revo 2 range spans three configurations — Basic, Pro, and Touch — that share the same core mechanical parameters: 11 degrees of freedom with 6 active joints, 383 g weight, 160 mm height, at least 50 N five-finger grip strength, at least 15 N pinch strength, and at least 20 kg full load. The Basic version covered here (right-hand code XRR) communicates over RS-485 and CANfd and accepts a 12–28 V supply, while the Pro and Touch versions add EtherCAT connectivity and a wider 12–64 V input range, and the Touch version adds a multi-dimensional fingertip tactile module with tactile adaptive control. The manufacturer notes that the Revo 2 platform can be equipped with multi-dimensional tactile perception capabilities; in the Basic configuration, the tactile module is not fitted. All versions support OTA online upgrades and the same secondary-development toolchain.

Technical Specifications

All figures above are drawn from the manufacturer's published documentation and should be confirmed against the current official datasheet during quotation, as specifications can be revised between production batches.

What do the 11 degrees of freedom actually mean?

The Revo 2's eleven degrees of freedom are distributed to mirror the functional anatomy of a human hand. In practice this means six motor-driven joints shape the hand's posture while passive compliance lets the fingers conform naturally around objects. Repetitive control precision of 0.1° allows fine, repeatable positioning across that workspace, and full flexion or extension completes in 0.65 seconds or less.

How is the Revo 2 Basic controlled and programmed?

Control flexibility is one of the platform's defining traits. Each joint supports five documented control modes: position with time, position with speed, pure speed, current, and PWM, giving developers everything from precise trajectory tracking to direct effort control. Communication runs over RS-485 or CANfd at rates up to 1 kHz for high-speed real-time coordination with a host robot; the documented default device ID for a right hand is 127. The SDK supports Python and C, is compatible with Linux, Windows, and ROS, and supports customizable gestures alongside OTA online upgrades.

Who is the BrainCo Revo 2 Basic Right Hand for?

The Revo 2 Basic right hand is aimed at robotics teams that need a production-quality dexterous end effector without the cost of tactile sensing. Because the Basic version keeps the same mechanics, grip performance, and SDK as its siblings while using the widely available RS-485 and CANfd buses, it suits projects where deterministic communication and programmability matter more than fingertip tactile feedback. Buyers who require EtherCAT or tactile adaptive gripping should evaluate the Pro or Touch configurations instead.

What is the BrainCo Revo 2 Basic Right Hand used for?

1. Humanoid robot integration — serving as the right-hand end effector on full-size or research humanoid platforms that require human-like grasping.
2. Manipulation and grasping research — providing a repeatable 11-DoF testbed for grasp planning, control algorithms, and compliance studies.
3. Teleoperation development — mapping operator hand poses to the hand's customizable gestures and multi-mode joint control for remote manipulation work.
4. Robotics education — giving students hands-on experience with servo control, feedback loops, and SDK-driven development on Linux, Windows, and ROS.
5. Automation prototyping — evaluating adaptive gripping of varied objects in pick-and-place or tool-handling scenarios within its 20 kg full-load envelope.
6. Embodied AI development — acting as a physical actuator for software teams building gesture, manipulation, or task-learning pipelines through the Python/C SDK.

Frequently Asked Questions

How many degrees of freedom does the Revo 2 Basic have?

It has 11 degrees of freedom in total, of which 6 are active joints driven by 6 motors; the remainder are passive degrees of freedom that provide natural finger compliance.

What is the difference between the Basic, Pro, and Touch versions?

All three share the same mechanics and grip performance. The Basic (XRL/XRR) uses RS-485 and CANfd with a 12–28 V supply; the Pro adds EtherCAT and a 12–64 V range; the Touch adds EtherCAT, the wider voltage range, and a multi-dimensional fingertip tactile module with tactile adaptive control.

Does the Basic version include tactile sensing?

No. The manufacturer's specification table lists no tactile module for the Basic version; multi-dimensional fingertip tactile sensing is a feature of the Touch configuration.

How strong is the grip?

The published figures are a five-finger grip strength of at least 50 N, a pinch strength of at least 15 N, and a full load rating of at least 20 kg, with a maximum thumb-to-index opening of 100 mm.

What software and operating systems are supported?

The SDK supports Python and C and is compatible with Linux, Windows, and ROS, with customizable gestures, five joint control modes, and OTA online firmware upgrades.

What protections are built in?

The hand includes current protection, stall protection, high-temperature protection, and anti-collision protection, plus status indication via a back-of-hand light and a multi-function button for reset and factory restore.
