让机器人拥有人类般的精细触觉

Core Insights - A breakthrough research from Hong Kong University of Science and Technology (Guangzhou) has developed a dual-modal tactile sensor array with sub-millimeter resolution, enabling robots to achieve tactile perception similar to human fingertips [1][2]. Group 1: Research and Development - The research team, led by Associate Professor Zi Yunlong, aims to replicate human-like tactile perception in robots, addressing the challenge of achieving high resolution and multi-modal sensing simultaneously [2][3]. - The new sensor can identify material types, softness, and quantify elastic modulus based on the frictional effect, achieving a material identification accuracy of 99.4% and a softness identification accuracy of 100% [3][4]. - The team has successfully miniaturized the sensor unit from 5 millimeters to 0.35 millimeters, achieving a significant leap in sub-millimeter resolution [5]. Group 2: Applications and Future Directions - The technology has potential applications in high-security product traceability and anti-counterfeiting by creating unique "physical fingerprints" based on subtle hardness differences [5][6]. - In the fields of smart home and industrial sorting, robots could accurately select the best fruits or identify specific items among visually identical products [6]. - Future research will focus on more complex tactile dimensions, such as sliding perception and three-dimensional force, while actively seeking collaboration opportunities with industry [6].
