Recently, the bionic dexterous robot hand - F-TAC Hand, jointly developed by Beijing Institute of General Artificial Intelligence, Peking University and other units, was officially released, marking a key technological breakthrough in the field of high-precision tactile perception and intelligent operation in China. As the world's first robot hand to achieve "full-hand high-resolution tactile perception + complete movement ability", F-TAC Hand not only fills the gap in China, but also has a milestone in the world, and its emergence may reshape the interaction paradigm between robots and the real world.
Ⅰ Technological innovation: 30,000 tactile pixels drive "human-grade" fine operations
The most outstanding technical highlight of the F-TAC Hand is its ultra-high-resolution haptic system. According to official data, high-density tactile sensors are deployed in about 70% of the surface of its palm, with an overall resolution of 10,000 tactile pixels per square centimeter, or 30,000 pixels per square decimeter, far exceeding the international mainstream bionic hand products.
For example, the tactile resolution of the robot hand jointly created by OpenAI and Google DeepMind is about a quarter of that of the F-TAC Hand. This increase in magnitude allows the F-TAC Hand to accurately perceive object shapes, materials, textures, and even sliding trends, significantly improving the accuracy and robustness of gripping and manipulation.
In addition, the F-TAC Hand's motion system is modeled after the human hand, using a rope drive mechanism to control the flexion and extension of the five fingers, supplemented by the automatic reset design of the joint torsion spring, achieving a total of 15 degrees of freedom and a maximum of 10 Newton grip force. Its grasping performance is close to that of humans, and it can stably handle fragile objects such as eggs and table tennis balls, with a grasping success rate of up to 99.5%, far exceeding the current commercially available robot hand products.
Ⅱ Perception + cognition: create a bionic hand that "knows how to grasp".
In order to achieve the "unity of knowledge and action", the R&D team also proposed a set of intelligent grasping algorithms. Based on probabilistic modeling, the algorithm learns 19 common human grasping methods, and can dynamically plan the next action in real time according to the remaining palm space and the distribution of surrounding objects.
Experimental data show that in complex environments, the grasping success rate of F-TAC Hand with haptic feedback is increased from 53.5% to 100%, and it has a strong adaptability to execution errors and environmental interference. In addition, the team adopted a modular combination method to lay out 17 different types of tactile sensors in 6 modes, realizing the integration of sensor structure and bionic motion.
The system is also highly scalable, providing an underlying support platform for future integration with AI models, edge computing modules, and IoT systems.

Ⅲ Application expansion: medical, manufacturing, and family services are in full bloom
The F-TAC Hand has a wide range of advantages that make it promising for a wide range of applications, especially in the following key areas:
Ⅳ Medical rehabilitation and intelligent prosthetics
In terms of surgical assistance, the high sensitivity and precise control ability of F-TAC Hand can be widely used in neurosurgery, minimally invasive surgery and other scenarios that require high operation accuracy. At the same time, combined with brain-computer interface technology, it is expected to further improve the naturalness and responsiveness of prosthetic control.
At present, there are about 24 million people with physical disabilities in China, of which more than 8 million are with upper limb disabilities. The localization of bionic hands can effectively alleviate the problem of dependence on imports of prosthetic products, and provide patients with a more economical, intelligent alternative to the real hand experience.
Ⅴ High-precision manufacturing and hazardous operations
F-TAC Hand is suitable for high-precision and repeatable operation scenarios, especially for complex assembly lines, such as semiconductor packaging and testing, auto parts assembly, 3C equipment maintenance, etc. In addition, its excellent durability and sensing capabilities give it unique advantages in extreme environments such as nuclear power facilities, deep-sea exploration, and aerospace.
Ⅵ The core component of the home service robot
With the intensification of China's aging society and the improvement of quality of life, the service robot market is growing rapidly. F-TAC Hand can be embedded in various housekeeping, escort, and disability assistance robots to achieve complex tasks such as cleaning, cooking, and nursing. According to IDC's forecast, the global home service robot market will reach 150 billion yuan by 2030, with a compound annual growth rate of more than 20%.
Ⅶ Far-reaching significance: to promote China's robots towards intelligence and localization
The success of F-TAC Hand is not only a breakthrough in robot end-effector technology, but also represents a key progress in China's autonomous and controllable robot core technology. For a long time, the domestic robot industry has a high dependence on foreign countries in the field of core components such as dexterous hands, reducers, and control systems, which seriously restricts industrial upgrading.
The F-TAC Hand is a localization path from the underlying material design, sensor architecture to motion control algorithm, which provides a feasible model for breaking the international technology blockade and alleviating the "stuck neck" problem of high-end robots.
More importantly, this achievement also promotes the practical implementation of Embodied Intelligence research. It emphasizes that the agent must have a closed-loop system of perception-movement-cognition, and F-TAC Hand is the embodiment of this concept.
Ⅷ Ongoing challenges: Mass production, durability, and ethical thinking cannot be overlooked
Although the F-TAC Hand has been prototype-validated, there are still bottlenecks before it can be commercialized on a large scale:
1. Cost problem: The current rectification mechanism is about 500,000 yuan, and the industrialization needs to be controlled below 200,000 yuan in order to enter the rehabilitation and manufacturing markets on a large scale.
2. Sensor stability: Under long-term use conditions, how to improve the fatigue resistance, dust resistance, and waterproof ability of tactile sensors still need to be continuously optimized.
3. Generalization of intelligent algorithms: Most of the existing grasping strategies are based on common object scenarios, and how to achieve robust processing of unknown environments and deformed objects is still a challenge.
At the same time, in the process of gradually replacing some human positions, the bionic hand has also brought about social problems such as occupational substitution and ethical boundaries. For example, the International Labour Organization (ILO) has estimated that robotic automation could affect 10% of the world's job mix over the next 10 years. This requires the policy level to plan education and retraining programs in advance to avoid the social pain caused by technological development.
Ⅸ Prospects: From prototypes to core components of agents
Going forward, F-TAC Hand will continue to evolve in the following directions:
* Deep integration with AI large models: improve intent recognition and task decision-making capabilities;
* Equipped with domestic chips and controllers: promote full-link localization;
* Standardized module design: accelerate the entry of bionic hand parts into the ecological industrial chain.
With the coordinated development of biomimetic technology, semiconductor technology, AI algorithms and materials science, future robots will no longer only "understand commands", but also "touch details, grasp changes, and cope with challenges".
F-TAC Hand is undoubtedly a crucial leap forward for our country in this process.
If there are no surprises, it will not only reshape the standard of robot hand interaction in the technical dimension, but also enhance the influence of China's robot industry on a global scale. This is a technological breakthrough, and it is a microcosm of China's innovation ability in the era of intelligent manufacturing.
