A study on the SRF array to detect the obstacles of the mobile robot's path

이동 로보트 경로상의 장애물 검지를 위한 SRF (Sonic Range Finder) Array에 관한 연구

This paper gives the Sonic Range Finder(SRF) Array which detects the unknown obstacles on the mobile robot's path. This SRF Array gives mobile robot's circumstance information wider, processes and transfers them to the locomotion module to construct the modify path. In this system, 8 pairs of the 40 KHz ultrasonic sensors constitute the SRF Array, including a pair of reference sensors to correct the errors, 4051 analog multiplexer and demultiplexer swtch the sensor with time and 8031-on chip micro computer controls processes the data and communication the others.
