Autonomous soccer robot using triple infra-red sensor for ball detection

Abstract

This research work describes about an autonomous microcontroller-based mobile robot for a robot soccer competition. The competition field as shown in the methodology is equipped with white lines to serve as the guidance path for competing robots. Two prototypes of soccer robot embedded with the Basic Stamp II microcontroller have been developed. Two servo motors were used as the drive train for the first prototype whereas the second prototype used two DC motors as its drive train. To sense the lines, light-dependent resistors (LDRs) supply the analog inputs for the microcontroller. The performances of both prototypes were evaluated. The DC motordriven robot has produced better trajectory control over the servo motors and has brought the team into the final round.
