A study of performances on an automatic IEEE 802.11g wireless-standard robot using infrared sensors

Abstract

This paper presents a study of performances on an automatic wireless robot using IEEE 802.11g standard and infrared sensors. The robot acts a personal computer (PC) controlling equipments (e.g. motors) through a printer port. Window XP is setup on the PC robot which is received a command from notebook (only Start / Stop commands) linked through the use of a wireless router and a real-time streaming protocol (RTSP) program. The study of performances on the automatic wireless robot is tested in three patterns of obstacles i.e. ┐,┌ and Π. In the results, the robot can avoid a hindrance when infrared sensors detect the obstacles, then it will move backward direction in the length of 60 cm and move forward direction in the angle of 45°. The sensors can detect colors (except black color) and opaque but they cannot detect clear glass. In addition, the delay time and the maximum distance of transmitting and receiving images are approximately at 0.1s and 40m, respectively.
