BrainCo Revo 2 Basic Left Dexterous Bionic Hand (XRL)
Every humanoid project reaches the same awkward moment: the right hand works, and the left hand is still a drawing. The BrainCo Revo 2 Basic Left Dexterous Bionic Hand (XRL) is meant to end that moment. It is a five-finger bionic hand for robot integration and research, and it is identified in software by its own default device ID, 126, so that it can sit beside its right-hand counterpart on one communication bus without confusion.
The product is available through this page, by quotation.
Background
BrainCo and the Revo 2 family
BrainCo is the brand behind the Revo line of bionic hands. The name Revo 2 marks the second generation, and the same store network lists a Revo 1 Intelligent Dexterous Bionic Hand for buyers who want to compare generations. Within Revo 2, the fact sheet names three versions: Basic (XRL for the left hand, XRR for the right), Pro (XEL and XER) and Touch (XTL and XTR). This page covers the Basic left hand, XRL. The sources do not give a corporate history or a manufacturing location, so none is claimed here.
Where the Basic version sits
The published description calls Revo 2 a bionic dexterous hand for robot integration and research. The Basic version is the entry point of the family. It keeps the common mechanical platform of 11 degrees of freedom, of which 6 are active joints, and it communicates over RS-485 or CAN FD. Buyers who want a wider supply range or other additions can look at the sibling versions, which are discussed below. The whole family is collected in the BrainCo Revo 2 category, and related end effectors are grouped under Hands.

What makes the Basic version different from the Pro and Touch versions?
The clearest published difference is electrical. The Basic version is specified for a 12-28V supply, whereas the Pro and Touch versions are listed at 12-64V. The static current of the Basic version is 65 mA at 24V, against 115 mA at 24V for the other two. Its no-load average current is 350mA at 24V, against 390mA at 24V, and its maximum current is 4.6 A at 24V, against 4.65A at 24V. Repetitive control precision is the same across the family, at 0.1°.
In practical terms, a robot whose power rail sits comfortably inside 12-28V gains nothing from the wider range and can take the Basic hand. A platform running a higher-voltage bus should look at the BrainCo Revo 2 Pro Dexterous Left Hand (XEL) or the Brainco Revo 2 Touch Biomimetic Dexterous Left Hand (XTL). The fact sheet does not detail what else distinguishes those versions, so the datasheet should be checked for any mechanical or sensing differences before a choice is made.
How is the XRL controlled and protected?
The Basic version can be commanded over RS-485 or CAN FD. The interface sits under the wrist, and the connector model is BM05B-PASS-TFT(LF)(SN). By default the left hand answers at ID 126 and the right hand at ID 127, which is useful when two hands share a network.
On the control side, the published feedback modes are position, velocity and current, together with cascaded control and compliance control. Protection covers current, stall, high temperature and anti-collision events. For development, the SDK supports Python and C and is compatible with Linux, Windows and ROS systems, and the hand supports OTA online upgrades. The sources do not state a communication rate or a cable length, so teams with strict bus timing or routing requirements should ask for both at quotation.
Who is the BrainCo Revo 2 Basic Left Dexterous Bionic Hand (XRL) for?
Robot integrators building humanoids or dual-arm manipulators need a left hand that matches the right. For them, the XRL and its sibling, the BrainCo Revo 2 Basic Right Dexterous Bionic Hand (XRR), form a pair on the same electrical interface.
University and industrial laboratories studying grasping, teleoperation or learning-based manipulation will value the open SDK and the ROS compatibility. Teams with a 12-28V power architecture and a CAN FD or RS-485 bus will find the Basic version a direct fit. Buyers who need a higher supply voltage, or the additions of the other versions, should consider the Pro or Touch hands instead.
What is the XRL used for?
- Humanoid left-hand manipulation: gives the left arm of a humanoid a five-finger end effector with 11 degrees of freedom.
- Bimanual research: pairs with the right-hand XRR for two-handed grasping and handover studies.
- Grasp and pinch experiments: the published full fist and pinch forces support tests of power and precision grips.
- ROS-based development: the SDK works with Linux, Windows and ROS, so control code can be built in familiar tools.
- Compliant interaction trials: position, velocity, current and compliance control allow work on gentle contact.
- Teaching and demonstration: the quiet operation and protective functions suit classroom and exhibition benches.

Frequently Asked Questions
Is the XRL a left hand only?
Yes. XRL is the left-hand code of the Basic version, and XRR is the right-hand code. Their default device IDs are 126 and 127 respectively.
What communication interfaces does it offer?
The Basic version communicates over RS-485 or CAN FD. The connector is located under the wrist.
What supply voltage does it need?
The published supply voltage for the Basic version is 12-28V. The current figures in the table are given at 24V.
Which software environments does the SDK support?
The SDK supports Python and C and is compatible with Linux, Windows and ROS systems. The hand also supports OTA online upgrades.
What protection does the hand include?
The published protections are current, stall, high-temperature and anti-collision protection.
Is the ingress protection rating known?
The manufacturer has not published an IP rating, nor the materials or the service life. These are confirmed at quotation.
Where can I buy the BrainCo Revo 2 Basic Left Dexterous Bionic Hand (XRL) and what does it cost?
It is available through this page, by quotation. No price is shown; the cost is provided in the quotation after your requirements are confirmed.
Summary
A robot is only as capable as its weaker hand, and the XRL addresses the left side with a defined identity, a standard bus and an open SDK. Its published figures cover 11 degrees of freedom, a 383 g mass, a 160 mm height and at least 50N of grip, within a 12-28V supply. Some details, such as width, IP rating and cable length, remain unpublished and are confirmed at quotation. For a matched pair or a single left-hand end effector, this page is the starting point.
