THEORETICAL AND EXPERIMENTAL RESEARCH ON THERMAL SENSOR FOR ROBOT

A thermal sensor for material identification is proposed. This paper describes the model, design, and testing of the sensor. Some factors of the detector which affect the performances of the sensor are discussed. A new concept called the thermal sense characteristic parameter is advanced, and the relationship between the thermal sense characteristic parameter and the response of the sensor is given. A method for computing thermal sense characteristic parameter from the response of the sensor is indicated. Based on our developed sensor, the correction rates of the testing results of the seven materials (copper, aluminum, steel, rubber, PCB, polyflon, paper) from 130 identifications are 100%.
