Array type flexible electronic skin for robot tactile feedback

Abstract

The invention discloses array type flexible electronic skin for robot tactile feedback. The array type flexible electronic skin comprises a tactile feedback response system, a plurality of accommodating shells distributed in an array and a plurality of flexible electronic skin units respectively arranged in the accommodating shells, and the plurality of accommodating shells are connected through splicing parts; each flexible electronic skin unit comprises a substrate, an electrochromic pressure display unit located on the substrate and a triboelectric pressure sensitive unit located on the electrochromic pressure display unit; and the tactile feedback response system is connected with the electrochromic pressure display units and the triboelectric pressure sensitive units. The array type flexible electronic skin can be applied to a robot in a large area, meanwhile, the multiple flexible electronic skin units distributed in an array mode are connected together, moving adjustment of the array type flexible electronic skin can be facilitated, the array type flexible electronic skin can be conveniently applied to different positions of the robot, the detection range is large, detection and real-time visual display of pressure magnitude and distribution can be completed, and dependence on a power supply is low.

Description

technical field [0001] The invention relates to the technical field of robots, in particular to an array type flexible electronic skin for tactile feedback of robots. Background technique [0002] At present, the commonly used technology in the field of tactile feedback for robots is the tactile response system based on pressure sensors, which is mainly composed of pressure sensors and signal processing systems. However, pressure sensors in the field of robot tactile feedback are all applied to relatively fixed positions of the robot, such as joints, and the detection position is very limited. Therefore, the tactile feedback technology cannot be applied to the robot surface in a large area. In addition, in terms of the signal processing system, the relevant information about the pressure is mainly presented through the display, and the pressure-related information cannot be presented on the pressure contact surface, and the device needs continuous external power supply to m...

AI Technical Summary

Problems solved by technology

However, pressure sensors in the field of robot tactile feedback are all applied to relatively fixed positions of the robot, such as joints, and the detection position is very limited.

Therefore, the tactile feedback technology cannot be applied to the surface of the robot in a large area.

In addition, in terms of the signal processing system, the relevant information about the pressure is mainly presented through the display, and the relevant information about the pressure cannot be presented on the pressure contact surface, and the device needs continuous external power supply to maintain normal work

When the power is disconnected and the robot is in contact with the force in the external environment, we cannot know the relevant information of the pressure, and the current commercial pressure sensors also have the problems of power dependence and high energy consumption.
