my country’s robot bionic hand research has made new breakthroughs, precisely grasping and “touch” like human hands – Passionategeekz

Passionategeekz According to CCTV News, recently, a joint scientific research team composed of Beijing General Artificial Intelligence Research Institute, Peking University and other units developedThe world’s first full-hand high-resolution touch perception and complete movement abilityrobot bionic hand. With it, robots can not only accurately grasp items, but also “feel” strength and position like human hands.

Passionategeekz learned from the report that in the picture, the one that is performing “finger dance” is the latest achievement of my country’s scientific research team – bionic smart hands, also known as F-TAC Hand. 70% of the surface of its palm is covered with high-resolution haptic sensors, with a spatial resolution of up to 0.1 mm.It is equivalent to 10,000 tactile pixels per square centimeterthis is much stronger than the perception ability of other robots on the market.

In addition to being sensitive to touch, the scientific research team also equipped the bionic hand with a “smart brain”, a new algorithm that can imitate human grasping habits. In the past, when robots were conducting crawling tasks, they could only take items one by one; and the algorithms equipped with bionic skillful hands gave it the ability to “think independently”. When it performs a task,The next action will be dynamically planned based on the remaining space of the palm after grabbing the item, the position and shape of surrounding objects.。

During the research and development process, scientific researchers found that existing tactile sensing technologies have shortcomings in coverage, resolution and durability, and it is difficult to make bionic skillful hands useful in life. In order to overcome this problem, the scientific research team took a different approach.Develop a new tactile perception solution。

The new tactile perception solution allows bionic hand to have higher tactile sensitivity, laying the foundation for subsequent research and development. Subsequently, the scientific research team imitated the human hand structure and cleverly used 17 high-resolution tactile sensors.Combine together in 6 different ways. In this way, bionic hand can both accurately perceive and move nimblely.

Experimental results show that compared with ordinary robotic skilled hands without tactile feedback, bionic skilled hands show significant adaptability advantages when facing execution errors and object collision risks, and there will be more applicable scenarios.
