Embodiment Construction

[0042] In order to fully understand the purpose, features and effects of the present invention, the present invention will be described in detail through the following specific embodiments, but the present invention is not limited thereto.

[0043]The tactile sensor based on the friction generator provided by the present invention includes: at least one friction generator, wherein the two opposite surfaces of the friction generator constitute a friction interface, and when an external force acts on the friction generator, the friction interfaces rub against each other, and the friction generator Output pressure electric signal corresponding to external force. Wherein, the tactile sensor based on the friction generator may include one friction generator, or may include multiple friction generators, which can be selected by those skilled in the art according to needs, which is not limited here. If the tactile sensor based on frictional generators includes multiple frictional gen...

Abstract

The invention discloses a tactile sensor based on friction power generators and a robot tactile perception system. The tactile sensor comprises at least one friction power generator. Each friction power generator comprises a first electrode layer, a first high-molecular polymer insulating layer and a second electrode layer which are laminated in turn. The two opposite surfaces of each friction power generator form friction interfaces. When external force acts on the friction power generators, the friction interfaces perform mutual friction, and the friction power generators output pressure electric signals corresponding to external force. The first electrode layer and the second electrode layer form the output ends of the friction power generators. According to the tactile sensor based on the friction power generators and the robot tactile perception system, the structure is simple, and sensitivity and accuracy are high.

Description

technical field [0001] The invention relates to the technical field of sensors, in particular to a friction generator-based tactile sensor and a robot tactile perception system. Background technique [0002] Robots have been widely used in industrial production and have gradually entered people's daily life. The development and application of sensor technology has made robots increasingly intelligent, gradually possessing vision, touch and hearing capabilities. The sense of touch can enable the robot to accurately know the shape and size of the object, so as to determine the appropriate picking force, ensure that the picked object is not damaged, and also ensure the safety of the robot itself. [0003] Most of the robots in the prior art realize tactile perception based on pressure sensors, piezoelectric elements, contact electrodes, etc., but these sensors have complex structures, low sensitivity, low accuracy, etc., and have large nonlinearity and output fluctuations when...
