The BrainCo Revo 2 is the lightweight five-finger robot hand in the RevoLimb family from BrainCo (Chinese 强脑科技). 6 of its 11 degrees of freedom are active; the thumb has 2 active and 1 passive joint, and each other finger 1 active and 1 passive. Weighing 383 g without the wrist, it offers a five-finger grip of 50 N or more, a whole-hand load of 20 kg or more and 0.1° repeatability.
The Basic version uses RS485 or CAN FD, while the Pro and Touch versions add EtherCAT; Touch adds 3D force and proximity sensing per finger. Unitree G1 integration for the Revo 2 is published in both BrainCo and Unitree repositories, and the hand is among the Booster T2's factory end effector options. BrainCo sells the hand on request only. Robotlar.org offers the Revo 2 to research labs and humanoid or robot arm integrators in Turkey through enterprise sourcing, technical specification support and integration engineering.

Values from the BrainCo RevoLimb documentation, 13 November 2026. The website gives the voltage as 9 to 28 V and 9 to 64 V; some pages call the Pro version Advanced. Version, hand side and quantity are set in the quotation.
Revo 2 Basic
Grasping and teleoperation projects on RS485 or CAN FD that do not need tactile data.
Revo 2 Pro
Robot arms with an EtherCAT line and platforms that need the wider voltage range.
Revo 2 Touch
Work that needs a tactile compliant grasp with contact force and proximity data.
The use cases the manufacturer defines for the BrainCo Revo 2.
6 of the Revo 2's 11 degrees of freedom are active.
The weight without the wrist is 383 g, and the height from palm base to middle fingertip is 160 mm.
The manufacturer's documentation gives a five-finger grip of 50 N or more, a pinch force of 15 N or more and a whole-hand load of 20 kg or more.
The Revo 2 comes in three versions, as left and right hands.
The hand supports position, speed, current, graded and compliant control modes.
The Revo 2 is supported for the Unitree G1 from both sides.
Booster's T2 documentation lists the Revo 2 among the T2's end effector options; optional end effectors are installed, wired, configured and tested at the factory.
BrainCo publishes its software in the BrainCoTech organisation on GitHub.
2 active and 1 passive in the thumb, 1 active and 1 passive in each other finger.
Weight without wrist; height 160 mm.
Between thumb and index finger.
With five fingers; pinch 15 N or more, whole-hand load 20 kg or more.
RS485, CAN FD; EtherCAT on Pro and Touch.
3D force and proximity sensing per finger.

The BrainCo Revo 2 is a candidate for all of these jobs; in each scenario our catalogue also holds other bodies that can do the same work. The right robot follows from the job itself and the delivery timeline.
A lab running a G1 wants a five-finger hand instead of a three-finger one. For the Revo 2 both BrainCo's G1 integration repository and Unitree's brainco_hand_service repository are published; teleoperation runs through Unitree's xr_teleoperate tool. Mechanical mounting and wiring are verified within the project.
An organisation buying a T2 wants the end effector installed and tested at the factory. Booster's documentation lists the Revo 2 among the T2 options, and the T2_31dof_Revo2Hand model is ready for simulation. The hand choice is written into the T2 quotation's configuration.
When a collaborative arm has a tight payload limit, a 383 g hand leaves margin. The ROS 2 package comes with ros2_control, Gazebo and MoveIt; on arms with an EtherCAT line the Pro version is chosen.

The most common questions about the BrainCo Revo 2.
The BrainCo Revo 2 is a lightweight five-finger robot hand from BrainCo (Chinese 强脑科技). 6 of its 11 degrees of freedom are active, and it weighs 383 g without the wrist. It comes in Basic, Pro and Touch versions.
Yes, there are two official sources. BrainCo's unitree-g1-brainco-hand repository describes integration on the G1's 23 and 29-DoF versions with dual RS-485 and ROS 2, and Unitree's brainco_hand_service repository states that the G1 can be equipped with the Revo 2. Whether the hand is sold pre-integrated with the G1 is not stated; mounting and wiring are verified within the project.
Basic uses RS485 or CAN FD (by DIP switch) and runs on 12 to 28 V. Pro offers RS485, CAN FD and EtherCAT and runs on 12 to 64 V. Touch adds 3D force and proximity sensing per finger to the Pro.
The manufacturer's documentation gives a five-finger grip of 50 N or more, a pinch force of 15 N or more and a whole-hand load of 20 kg or more. Finger flexion and extension take 0.65 seconds or less.
Yes. Booster's T2 documentation lists the Revo 2 among the factory-installed end effector options, and the booster_assets repository includes the T2_31dof_Revo2Hand model.
brainco-hand-sdk is in C and Python under MIT; brainco_hand_ros2 offers ROS 2 Humble, ros2_control, Gazebo and MoveIt support (Apache-2.0). The revo2_description and brainco-description repositories contain URDF, MJCF and USD models.
Not published. The manufacturer states that the Touch version has 3D force, proximity and state logging per finger; the point count and measuring range are requested from the manufacturer in writing at the quotation stage.
For BrainCo products Robotlar.org provides enterprise sourcing, technical specification support and integration engineering. Supply into Turkey is planned per project; the scope of import, delivery and commissioning is itemised in the quotation. BrainCo sells the hand on request only; prices are not published and are requested through the quote form.
Lead time is stated in the quotation after confirmation from the manufacturer, based on quantity, version, hand side and import terms. Warranty scope and duration are stated in writing in the quotation according to the sourcing channel.
