Design of a mobile robot prototype for a relay race

摘要

This paper presents the design of a mobile robot which could follow a track and shoots a ball to the target set at the distance in a relay race. The design of the motor control circuit, speedometer, sensors and embedded control system are detailed respectively. Then the control strategy based on light tracking and recognition of barcode is designed, which can follow a line successfully and fire a shoot at right time. Finally, several issues are discussed for the improvement of the mobile robot in the relay race.
