Arrow-bot: A Teaching Tool for Real-Time Embedded System Course

Abstract

Abstract. This paper presents the design of a line following Arduino-based mobile robot for Real-Time Embedded System course at Universiti Tun Hussein Onn Malaysia. The real-time system (RTS) concept was implementing is based on rate monotonic scheduling (RMS) on an ATmega328P microcontroller. Three infrared line sensors were used as input for controlling two direct current (DC) motors. A RTS software was programmed in Arduino IDE which relied on a real-time operating system (RTOS) of ChibiOS/RT library. Three independent tasks of software functions were created for testing real-time scheduling capability and the result of temporal scope was collected. The microcontroller succeeded to handle multiple tasks without missed their dateline. This implementation of the RTOS in embedded system for mobile robotics system is hoped to increase students understanding and learning capability.

The Factors that Influenced the Selection of Embedded Microcontroller for Teaching Embedded System Design and Interfacing Course

“…The demand for the embedded system course in electrical and electronics engineering and technology programs globally increases dramatically in the Internet of Things (IoT) era (Karunaratne, 2019;Karvinen & Karvinen, 2018;Malaoui, 2016;Martelaro et al, 2020;Rodriguez-Sanchez et al, 2016). Almost all the electrical and electronics engineering and technology programs include the course with the aim to expose the student to the current embedded system or microcontroller (Alavi & Meehan, 2019;Chancharoen et al, 2015;Karunaratne, 2019;Martelaro et al, 2020;Martínez-Santos et al, 2017;Sirkin et al, 2019;Zakaria, 2017). They start with the basic programming and microprocessor before the embedded system course.…”
