BrainCo Unveils Revo2, the World's Lightest Professional-Grade Dexterous Hand Capable of Lifting 20kg at WAIC 2025

On July 26, at the World Artificial Intelligence Conference (WAIC2025), BrainCo, one of the "Hangzhou Six小龙," unveiled its new generation of dexterous hand product, the BrainCo Bionic Dexterous Hand Revo2.

It is reported that this product, designed with reference to ergonomics, is an ultra-lightweight and ultra-compact bionic dexterous hand. Weighing 383g with dimensions of 16*7.6cm, it can achieve sub-millimeter operational precision of 0.1mm, a grip strength of 5KG, a load capacity of 20KG, and a grasp-to-weight ratio as high as 52.6. Equipped with multimodal tactile sensors, it supports a wide voltage range of 64V and various communication protocols, offering unlimited possibilities for embodied intelligent dexterous operations.

As the application boundaries of embodied intelligence expand from simple handling to delicate operations, with the increase in application scenarios and task complexity, robot designs are becoming more anthropomorphic to adapt to a wider range of environments. It is widely acknowledged within the industry that the engineering workload for dexterous hands accounts for half of the entire humanoid robot development, as the hand represents one of the most intricate and sophisticated aspects of robot functionality.

BrainCo has optimized bionic joints, precision transmission mechanisms, and implemented a whole-machine lightweight solution, making the product more like a human hand and more aligned with its functions. Through "millimeter-level subtraction," it has achieved "performance multiplication," realizing both lightweight design and high efficiency, elevating the grip-to-weight ratio to an industry-leading level.

BrainCo's Revo2 Bionic Prosthetic Hand is only 16cm in length, similar to a human female hand, but the entire hand weighs just 383g, equivalent to the weight of six eggs, which is 20% lower than the industry average. Despite its small size and light weight, the grip strength of Revo2 reaches up to 50N.

Generally speaking, most daily item operations in life require a grip strength of 30-40N. Therefore, a 50N grip strength means that Revo2 is capable of handling the majority of light industrial tasks and most scenarios. Additionally, it can effortlessly lift a 20-kilogram weight, equivalent to a full office water cooler bottle.

BrainCo has also strictly controlled the noise level of Revo2, ensuring it does not exceed 50 decibels, quieter than the background noise of a typical office. It is equipped with multiple protection mechanisms, including anti-collision, overcurrent, and overheating protection, guaranteeing safe and reliable operation in various environments and significantly reducing the probability of repairs. This makes Revo2 inherently suitable for diverse scenarios such as laboratories, home services, and industrial applications.

Revo2's tactile system is another major highlight. By ingeniously integrating tactile sensors into the finger structure, Revo2 is seizing the market advantage with its "lightweight and strong perception" features.

It is reported that, through a built-in 3D tactile sensor, Revo2 can accurately perceive the force information at the fingertips, precisely detect object hardness, texture, and force direction, and even distinguish the distance when approaching an object.

With this tactile system, products such as humanoid robots can not only "grasp" objects but also "feel" them, and even distinguish the hardness, texture, and fragility of different objects, enabling more precise object manipulation and achieving fine operations at the level of "hand-eye coordination." The most typical example is that this dexterous hand can easily complete tasks such as lighting a match.

From the perspective of application scenarios, whether it is domestic service robots needing to perform delicate tasks such as laundry, cooking, and organizing items, or industrial robots required to carry out complex operations like assembly, welding, and inspection, dexterous hands are an indispensable core component. With the rapid development of the embodied intelligence industry, they will see tremendous market demand. BrainCo stated that the company always starts from real usage scenarios, focusing on solving genuine needs as its core direction. In the future, it will continue to promote the deepened application and implementation of bionic dexterous hands across diverse scenarios.

Data shows that BrainCo was founded in 2015 by Han Bicheng during his Ph.D. studies at Harvard University and incubated in the Harvard Innovation Lab. Currently, BrainCo focuses on the research and development of non-invasive brain-computer interface technology, aiming to solve real-world problems through brain-computer technology. Its core products include a smart bionic hand, a smart bionic leg, and more. As one of the leading companies globally in non-invasive brain-computer interface technology, BrainCo has collaborated with multiple institutions and achieved application results in rehabilitation, healthcare, and other fields.

Brain-computer interface is a bridge for the brain to establish direct contact with the outside. Unlike invasive solutions, BrainCo has chosen a non-invasive route, using self-developed artificial intelligence algorithms to analyze neural signals in the brain. It currently owns more than 250 core invention patents and has filed over 600 patent applications.

BrainCo's intelligent bionic hand is the world's first mass-produced intuitive control smart bionic hand, allowing disabled individuals to perform high-precision actions such as writing and playing the piano. The price is only one-fifth to one-seventh of similar international products. The intelligent bionic leg helps amputees walk naturally, with a waterproof design adaptable to various terrains.
