Problems solved by technology

[0007] These robot flexible anti-collision skins all use arrayed micro-sensors. Due to the complicated manufacturing process, there are not many mature products.
Moreover, the manufacturing of the flexible anti-collision skin of the existing robot is complicated and the cost is high. It is difficult for the array type sensitive skin sensor to adapt to the robot body on the curved surface, the service life is short, and the sensor wiring is too much.
Therefore, the versatility is poor, it is not easy to maintain, and the maintenance cost is relatively high

Embodiment Construction

[0032] Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited by the embodiments set forth herein. Rather, these embodiments are provided for more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art.

[0033] In practical applications, the robot body usually does not come into contact with the human body / external environment. Once contacted, the robot needs to be stopped. Therefore, for the anti-collision skin, it is only necessary to be able to detect the presence or absence of collisions, and it is not necessary to obtain the location and collision of collisions. Force size. Based on this, in order to solve the problems existin...

Abstract

The invention discloses a flexible skin sensor and a collision detection system. The flexible skin sensor comprises two conductive layers formed by a flexible conductive material and an insulating isolation net positioned between the two conductive layers, and the two conductive layers contact when being squeezed by external force to be electrically on to enable a signal transmission circuit connected with the conductive layers to be on to output a collision signal. The flexible skin sensor can detect collision and play a role in buffering and is simple and reliable in structure, safe to use,low in cost and convenient for maintenance.

Description

technical field [0001] The invention relates to the technical field of collision detection, in particular to a flexible skin sensor and a collision detection system. Background technique [0002] With the development of robot technology, there are more and more "human-centered" robot application fields. For example, more and more robots are used in the fields of medical treatment and service robots. In the process of using robots, human safety Protection becomes the focus of attention. [0003] A common method of safety protection is to use a laser safety scanner to divide the detection range of the laser scanner into different areas to distinguish the degree of danger of the robot to people. When a person enters a dangerous area, reduce the speed of the robot or directly stop the robot. sports. This method is costly. [0004] Another means of safety protection is to collect the position information of the human body through the visual sensor, judge the relative position ...
