Evaluation of Method of Measuring Distance Between Object and Walls Using Ultrasonic Sensors

摘要

This paper is concerned with the development of an ultrasonic wave sensor system. A development of the sensor system a the robot which moves in the parallel to the wall is proposed. Ultrasonic wave frequency is 40 kHz. The sensor output is calculated with a PIC (computer), and it is displayed by a LCD screen. The architecture to introduce an ultrasonic wave sensor system for the moving environment is proposed. This architecture is simple, so it is applicable to measurement of the positioning control study. A sensor system was developed using only inexpensive and easily available components. Based on the information obtained while designing, manufacturing and testing the prototype, it was concluded that the system proved to be sufficiently capable for use by robots.
