BrainCo Revo 2 Basic Left Dexterous Bionic Hand (XRL)
Engineers rarely complain that a robot hand is too light; they complain that it is too heavy for the wrist that must carry it. The BrainCo Revo 2 Basic Left Dexterous Bionic Hand (XRL) is notable for the tension it addresses: per the published specification it weighs 383 g, yet it is rated for a maximum payload of at least 20 kg. For teams building the left side of a humanoid or a two-handed research cell, that combination is the reason to read further.

Background
BrainCo and the Revo 2 family
BrainCo is the manufacturer of the Revo range of bionic hands. According to the source material, BrainCo Revo 2 is a bionic dexterous hand for robot integration and research. The second generation is offered in three versions, each as a left and a right hand: Basic (XRL and XRR), Pro (XEL and XER) and Touch (XTL and XTR). The product described here is the left hand of the Basic version, with the version code XRL.
The same family includes a Revo 1 hand, which is listed separately in this store. Buyers comparing generations may wish to browse the BrainCo Revo 2 category, or the wider Hands category, to see the neighbouring products side by side.
Where the Basic version sits
The Basic version is the entry point of the Revo 2 line. It shares the eleven degrees of freedom, six active joints and the repetitive control precision reported for the other versions, but it differs in its electrical envelope. Its supply voltage is reported as 12-28V, whereas the Pro and Touch versions are reported as 12-64V. Its static current is reported as 65 mA at 24V, against 115 mA at 24V for the Pro and Touch versions. The Basic version communicates over RS-485 or CAN FD, and the connector is located under the wrist.

What makes the Revo 2 Basic different from the Pro and Touch versions?
On the figures the sources provide, the difference lies mainly in the electrical side. The Basic version is reported to run on 12-28V, while the Pro and Touch versions are reported to accept 12-64V. A team whose robot distributes power at a modest bus voltage will find the Basic range sufficient, whereas a platform with a higher-voltage supply may prefer to look at a sibling.
Current draw also differs. The Basic version is reported at 65 mA static and 350mA no-load average, both at 24V, with a maximum of 4.6 A at 24V. The Pro and Touch versions are reported at 115 mA static, 390mA no-load average and 4.65A maximum, all at 24V. The repetitive control precision is reported as 0.1° for all three versions. Beyond this, the fact sheet does not describe the Pro or Touch features in detail, so this page makes no claim about them. The Pro left hand is the BrainCo Revo 2 Pro Dexterous Left Hand (XEL), and the tactile version is the Brainco Revo 2 Touch Biomimetic Dexterous Left Hand (XTL).
How is the Revo 2 Basic Left hand controlled and integrated?
Per the published specification, the Basic version communicates over either RS-485 or CAN FD, through a connector located under the wrist. The connector model is BM05B-PASS-TFT(LF)(SN). Each hand carries a default device ID: 126 for the left hand and 127 for the right. This allows two hands to be addressed on one bus without conflict, which is useful for bimanual work.
The control modes reported are position, velocity and current feedback control, together with cascaded control and compliance control. Protection functions reported are current protection, stall protection, high-temperature protection and anti-collision protection. The SDK supports Python and C and is reported as compatible with Linux, Windows and ROS systems. OTA online upgrades are supported. All of this is a matter of the published specification, and the details should be confirmed against the datasheet at quotation.
On mechanics, the hand has eleven degrees of freedom of which six are active, with a reported repetitive control precision of 0.1°. The flexion and extension speed is reported as 0.65 s or faster, and the operating noise as 50 dB or less at 50 cm. The maximum opening between thumb and index finger is reported as 100 mm.
Who is the BrainCo Revo 2 Basic Left hand for?
The hand suits several kinds of buyer. Robot manufacturers and integrators building humanoids will find a left-hand unit that can be paired with its right-hand counterpart. Research laboratories studying manipulation, teleoperation or learning-based control can use the SDK and ROS compatibility to bring the hand into existing software. University teams and innovation centres in the region may value the Basic version as a lower-voltage, lower-current entry into five-finger robotic manipulation.
Buyers who need a matching right hand should consider the BrainCo Revo 2 Basic Right Dexterous Bionic Hand (XRR). Those whose platform supplies a higher voltage, or who require the other features of the Pro or Touch versions, should compare those siblings before requesting a quotation. Buyers who need a rated enclosure, specific materials or a particular cable length should note that these items are unpublished and must be confirmed at quotation.
What is the Revo 2 Basic Left hand used for?
- Humanoid robot integration. It serves as the left end effector on a humanoid platform, paired with a right hand.
- Bimanual manipulation research. Two hands with default IDs 126 and 127 can share one communication bus.
- Grasping studies. Position, velocity, current and compliance control allow experiments on how a grip is formed and held.
- Software development. The Python/C SDK on Linux, Windows or ROS lets teams build and test their own control applications.
- Teleoperation and demonstration. A five-finger hand with a reported 100 mm thumb-to-index opening supports remote-handling demonstrations.
- Teaching and laboratory work. Universities can use it to teach dexterous manipulation on real hardware.

Which communication interfaces does it use?
The Basic version is reported to communicate and be controlled over RS-485 or CAN FD. The connector is located under the wrist.
What supply voltage does the Basic version need?
The reported supply voltage is 12-28V. The Pro and Touch versions are reported at 12-64V, so the figures should not be mixed between versions.
Which software environments are supported?
The SDK supports Python and C and is reported as compatible with Linux, Windows and ROS systems. OTA online upgrades are also supported.
Is the IP rating or the material published?
No. The manufacturer has not published the IP rating, the materials, the width, the cable length or the service life; they are confirmed at quotation.

Summary
The interest of this hand lies in its balance: a reported 383 g mass against a payload rating of at least 20 kg, in a five-finger form that talks over RS-485 or CAN FD and is programmed through a Python/C SDK. The Basic version keeps to a 12-28V supply and a modest current draw, and it leaves the higher-voltage options to its siblings. For integrators and laboratories assembling the left side of a robot, this page is the starting point.
