Abstract

The present invention relates to a robot hand claw bionic finger surface flexible contact sensor array. It can simulate sensory neuron structure of human hand. It is characterized by that it utilizes the combination of microtype pressure sensor and microtype flexible air bag to form the invented bionic finger surface flexible contact sensor. On the sensor base plate several microtype pressure sensors are set, on every microtype pressure sensor the microtype flexible air bag is fixed and can be used for covering said microtype pressure senor so as to obtain the invented robot hand claw bionic finger surface flexible contact sensor array.

Description

technical field [0001] The invention relates to the field of robot bionics, in particular to a bionic finger surface flexible contact sensor array of robot claws made of a contact sensor array by combining a miniature air pressure sensor and a miniature soft air bag. Background technique: [0002] The finger surface contact sensor is a commonly used sensor for robots. The most commonly used sensors are contact switches, one-dimensional force sensors, multi-dimensional force sensors, PVDF films, and pressure-sensitive ink films. Recently, many scholars have developed different types of bionic sensors. For example, some scholars made PVDF films into extremely small filaments and cast them in flexible materials such as silica gel to make flexible contact force sensors, which promoted the development of bionic sensors. A large number of scholars Research and explore this kind of sensor in order to develop a sensor type with more practical value. [0003] The miniature air press...
