A case study as a class project of master-slave line tracer competition for undergraduate student education

This paper presents a case study of a class project for Junior level students in the curriculum of Mechatronics Engineering. As a class project of a sensor and signal processing class, a team of two students is required to build two line tracers, a master and a slave line tracer. The master line tracer is same as the line tracer that follows the line, but the slave line tracer is required to follow the master with limitation of sensors to follow the front master. The slave does not have communication with the master and any sensors to detect the line. The slave has only the distance sensor to detect the master. At the end of the semester, a master-slave line tracer competition is held to evaluate student grade for the class.
