Mechatronics is a branch of engineering whose final product should involve mechanical movements controlled by smart electronics. The design and implementation of functional prototypes are an essential learning experience for the students in this field. In this paper, the guidelines for a successful mechatronics project class are presented, evaluated, and discussed. Furthermore, the paper introduces a general mechatronic system design methodology that should equip students to carry out a successful mechatronics project in their undergraduate training. Three student projects at Philadelphia University, Jordan, are examined in detail, with descriptions of their goals, design, and implementation. (Contains 3 tables and 13 figures.)
