A robot safety skin and its preparation and use method

Abstract

The invention relates to a robot safety skin, which comprises an insulating base layer, a plane conductive layer, an insulating layer of a middle elastic screen, a dot matrix convex conductive layer, an upper insulating layer, an upper lead wire and a lower lead wire; the insulating base layer and the plane conductive layer are glued together , the dot-matrix raised conductive layer and the upper insulating layer are glued together, the gap between the flat conductive layer and the dot-matrix raised conductive layer is filled with an intermediate elastic mesh insulating layer, the upper lead is connected to the dot-matrix raised conductive layer, and the lower lead Connected to the plane conductive layer. The beneficial effects of the present invention are: the robot safety skin adopts an intermediate elastic mesh insulation layer to separate the plane conductive layer and the lattice convex conductive layer, and the middle elastic mesh insulation layer is compressed when the surface of the safety skin encounters an obstacle This causes a short circuit between the flat conductive layer and the dot-matrix raised conductive layer, thereby sending a dangerous signal to the robot control system and stopping the robot to ensure safety.

[0002] In the area where the robot works, people are often involved. When people do not pay attention, they will be touched by the robot and cause danger; to solve this problem, most of them currently use protective net protection, light curtain protection, photoelectric sensor protection, and visual detection protection. , Pyrosensor protection and other methods; but these protection methods have the disadvantage of taking up a lot of space

[0003] Intelligence is one of the main development directions of robot science research. The intelligence of robots is mainly manifested in the ability to work autonomously in unknown obstacle environments. This is the key to space and ocean exploration, military operations, dangerous environment operations, and even in the future service industry. The theory and technology that all robots must solve; robots must have environmental perception and real-time decision-making capabilities to work autonomously in unknown environments. The research on sensitive skin of robots is developed based on this demand, which can greatly improve the environmental perception of robots At present, the research in this field is very active. In China, Li Ping of Chongqing University has developed a kind of intelligent robot sensitive skin composed of ideal intelligent quartz piezoelectric material; Zhang Ling has developed a polypolar Vinyl fluoride (PVDF) bionic skin; Lin Xiaoyan, School of Science, Harbin Engineering University, developed a fiber optic smart skin; abroad, the laboratory of Professor Shinta, Saga University, Japan developed a tactile sensor system using pressure-sensitive conductive rubber; Yale University ( United States) Department of Electronic Engineering Cheung proposed a robot sensitive skin system; Cambridge University Artificial Intelligence Laboratory Antonio Bicchi and other detailed introduction of various contact force-sensitive sensors; Italian Pisa (Pisa) Institute of Clinical Physiology and Modena ( The Department of Physics of Modena University proposed a piezoelectric material tactile sensor array and a high-precision resonant pressure sensor based on piezoelectric properties, but these robot skins are still in the research stage and cannot be put into industrial application.
