An Autonomous Mobile Robot System for Advanced Microcontroller Education

Abstract

This paper introduces an autonomous mobile robot (AMR) system to enhance students' project planning, designing, and implementing capabilities while taking the advanced microcontroller course. The AMR system includes three parts of interface circuitries: the main I/O controls, parallel I/O extensions, and serial I/O extensions. In the circuitries of the main I/O controls, an AT89S51 single chip is used as the major controller to trigger LEDs, switches, voice, and RS232 controls; the interface circuitries of the parallel I/O extensions consist of LCM display, keyboard, and optical sensors; as for the serial I/O extensions, 7-segment display, A/D converter, DC motors' drivers, and memory controls are included. According to the students' feedbacks, introducing the ARM system in the advanced microcontroller course can attract more students interesting in designing the microcontroller-based applications and influence them in preparation for the senior laboratory project.
