BrainCo Revo 2
The BrainCo Revo 2 is a five finger bionic dexterous hand weighing 383 grammes at 160 by 76 millimetres, driving 11 degrees of freedom through six motors to grip at 50 newtons, lift 20 kilogrammes and place to 0.1 millimetre precision, a grip to weight ratio of 52.6, offered in Basic, Pro and Touch versions with RS485, CAN FD and kilohertz EtherCAT communication, multimodal tactile sensing on the Touch, and SDK support spanning Linux, Windows and ROS.
BrainCo Revo 2
Every gramme at the end of a robot's arm is paid for twice: once by the wrist that swings it and again by the balance controller that compensates for it, which is why the most important number on the BrainCo Revo 2 is a ratio. This five finger bionic hand from BrainCo, the Hangzhou neurotechnology company whose hand engineering was forged in prosthetic limbs, weighs 383 grammes, occupies 160 by 76 millimetres, roughly the footprint of a smartphone, and yet grips at 50 newtons and supports loads to 20 kilogrammes: a grip to weight ratio of 52.6 that stands among the strongest of any dexterous hand sold. It is the arithmetic humanoid designers shop by, and it explains why the Revo 2 became the hand the industry actually fitted, deployed across dozens of robotics companies and offered as the five finger option on major humanoid platform education tiers.
Introduced in 2025 as the successor to the Revo 1, the Revo 2 drives 11 degrees of freedom through six precision motors and six active joints, places to sub millimetre 0.1 millimetre accuracy, and ships in three versions, Basic, Pro and Touch, the upper pair adding kilohertz EtherCAT communication and the Touch layering multimodal tactile sensing at the fingertips. It is, in short, the fielded standard of the range: the hand for programmes that need proven dexterity today, with the perception flagship Revo 3 above it for laboratories chasing the sensing frontier.

Background
The economics of distal mass
Hands are the most levered component on a humanoid: mounted furthest from every joint that moves them, their weight taxes shoulder torque, battery budget and whole body stability simultaneously, and BrainCo's own framing of the problem, that the dexterous hand represents close to half the engineering complexity of a humanoid robot, is borne out across the industry. The Revo 2's design brief descends directly from prosthetics, where the wearer's arm imposes the same constraint even more strictly: maximum function from minimum mass, which is precisely the trade the 52.6 ratio embodies.
The hand the platforms chose
Specification sheets are claims; fitment lists are evidence. Within a year of its arrival the Revo 2 was gripping across dozens of robotics companies, had been adopted as the five finger upgrade on leading humanoid education tiers, and was appearing in third party integration kits for research platforms, the kind of ecosystem position that only reliability at scale earns, and the reason the Revo 2 functions today as something close to the reference light dexterous hand.

The Revo 2 Versions
Revo 2 Basic
The Basic carries the complete mechanical offer, the full freedom, force, precision and protection set over RS485 and CAN FD, and serves as the value fitment for humanoid upgrades, education programmes and general research where fingertip sensing is not the mission.
Revo 2 Pro
The Pro adds kilohertz EtherCAT to the same mechanics: deterministic, high frequency communication for tightly synchronised control loops, the version for integrations where the hand must run inside real time architectures alongside arms and controllers.
Revo 2 Touch
The Touch completes the range with multimodal tactile sensing at the fingertips over the Pro's communication stack, giving grasp software contact awareness for force adaptive gripping, slip response and haptics informed research, the top fitment of the fielded line.
Which buyers does the Revo 2 suit?
The Revo 2 sells on the ratio and the record. Humanoid owners upgrading education and research platforms take Basic or Touch pairs, the proven path already walked across the humanoid catalogue's leading machines. Research groups take the Touch for grasp studies and manipulation work at accessible cost across research robotics, and the Basic where budgets stretch across whole cohorts in educational robotics. Integrators building light arms and mobile manipulators take the mass budget relief directly, prototyping teams take the SDK maturity, and programmes that outgrow the fingertip sensing graduate to the Revo 3 without leaving the toolchain, with complementary hardware from the sensors catalogue completing rigs.
Technology
Six motors, spent wisely
The Revo 2's freedom budget reflects grasping's real statistics: independent thumb abduction and adduction, the axis that distinguishes human grasping, receives dedicated actuation, while each finger pairs an actively driven flexion with passive compliance that lets the digit conform around objects, eleven degrees of freedom arranged so the six motors buy the grasp repertoire daily manipulation actually uses, at a fraction of the mass a fully actuated architecture would cost.
Precision from cascaded control
Sub millimetre placement from a 383 gramme hand is a control achievement as much as a mechanical one: closed loop servo regulation runs through cascaded layers that manage position, velocity and current together, holding 0.1 millimetre accuracy through the force range, with custom gesture definition letting integrators store and trigger the hand shapes their application repeats.
Grip that does not tire
For carries and holds that outlast a single actuation, the Revo 2's Turbo behaviour maintains clamping the way muscles do, by refreshing it: the fingers re-engage on a rapid cycle to sustain reliable force indefinitely, while current, stall, temperature and collision protections guard the hardware through the sustained duty, field proven dependability engineered as features rather than luck.
Integration as designed behaviour
The hand arrives expecting a robot around it: RS485 and CAN FD as standard, kilohertz EtherCAT on Pro and Touch, a wide voltage envelope to 64 volts, left and right units with configurable addressing for dual hand systems, and SDK support across C++, Python, Linux, Windows and ROS workflows, continuous with the wider Revo family so laboratories upgrade generations without rebuilding stacks.
What is the BrainCo Revo 2 used for?
- Humanoid platform upgrades: five finger dexterity fitted to research and education humanoids across the humanoid catalogue, the Revo 2's signature role.
