At the Shenzhen Intelligent Robot Smart Hand Industry Development Conference held on August 26th, the five kilogram dumbbell was easily gripped, the stirring action was seamless, and as the weight on the hand increased, the squeezing became tighter and tighter... Various forms and powerful smart hands depicted the future of the humanoid robot industry. As the end effector for robots to interact with the environment, dexterous hands are becoming a key breakthrough in driving the technological transformation of humanoid robots. On August 26th, at the Shenzhen Intelligent Robot Agile Hand Industry Development Conference, robots demonstrated how to pick up a stirring rod and stir beverages. The robot picked up a cup with one hand and a metal rod with the other hand, skillfully stirring inside the cup. After completion, the robot accurately placed the metal rod back onto the circular hole base with a diameter of only 8 millimeters, and the entire action was coherent and smooth. Robots from Tencent's laboratory have demonstrated the precision of current dexterous hand operations, and the application of artificial intelligence models has greatly improved the autonomous decision-making ability and upper limb flexibility of humanoid robots. According to industry insiders interviewed, only when humanoid robots have a pair of nimble hands can they better adapt to the existing environment of human society and truly enter people's daily production and life. Currently, on the basis of simple mechanical structures, there are more and more cutting-edge technologies and increasingly sophisticated functions for the integration of dexterous hands. The human hand has tactile perception ability. In order to simulate this ability, Pacini Perception Technology (Shenzhen) Co., Ltd. has independently developed a multidimensional array tactile sensor, which enables humanoid robots to have rich tactile sensations like humans and a closed-loop control system based on tactile feedback. It is reported that this dexterous hand with touch has the ability to be mass-produced and will play a role in industrial manufacturing, medical health, household services and other fields. Perception and manipulation are the two most important abilities of a dexterous hand Du Yipai, the head of the tactile business at Daimeng (Shenzhen) Robot Technology Co., Ltd., told reporters that the newly launched dexterous hand has 15 degrees of freedom and 20 motion joints, equipped with independently developed optical tactile sensors, which are comparable to the motion control and perception capabilities of human hands. The reporter saw on site that when the robot grasps an empty plastic cup, the gripping force is relatively light; As the staff gradually pours mung beans into the cup, the robot's hands can immediately sense the weight change as the weight gradually increases, and the force of grasping the plastic cup increases. On August 26th, at the Shenzhen Intelligent Robot Agile Hand Industry Development Conference, the audience experienced the joint movements of intelligent robot dexterous hands. As an interdisciplinary field of cutting-edge technologies such as deep biomimetics, flexible sensing, microelectromechanical systems, and high-performance materials, more and more companies that were not originally engaged in robot research and development have entered the field of dexterous hands, bringing new ideas and solutions to the industry. Based on core technologies such as self-developed inertial sensors and optical inertial hybrid motion measurement, the motion capture system developed by Beijing Nuoyiteng Technology Co., Ltd. provides technical support for the training of dexterous hands in humanoid robots, including human-machine collaboration, robot teaching training, and high-precision robot state measurement. The on-site staff stated that the dexterous hand trained through motion capture is closer to the true movement form of the human hand. The development of brain computer interfaces has injected new vitality into the development of dexterous hands and even humanoid robots. Zhejiang QiangBrain Technology Co., Ltd. has been engaged in the research and application of non-invasive brain computer interface technology. This year, it has started developing a dexterous hand that is compatible with humanoid robots and robotic arms. The newly launched touch dexterous hand can sense pressure, friction, force direction, surface material, etc. According to the news from the Shenzhen Intelligent Robot and Agile Hand Industry Development Conference, currently, Shenzhen is leveraging its advantages in innovation ecology, manufacturing system, innovative capital, global market, etc., promoting key core technology research and ecological cultivation of robots, and striving to build a global hub for innovative dexterous hand technology, high-end manufacturing aggregation, and integrated application demonstration.
