Learn Control Building Your Own Line Follower Robot at Home

In this work we present a low-cost Arduino-based line follower robot designed to be used in basic control courses following a project-based-learning approach. The idea is that students can learn electronics, programming, signal processing and control through the construction and control of this mobile robot both in practical teaching classes in the laboratory and in their personal time outside school hours. The robot has been used in the second year basic control course of the Telecommunication Engineering degree of the University of Seville with over 180 students. The pedagogic objectives of this course and how it has affected the design are discussed. In addition, the design of the robot is presented in detail.
