In this paper we propose a new type educational program for Mechatronics design which contributes to develop the physical sense and problem solving ability of the students who study Mechatronics design. For this program we provide a new handicraft kit of 4-wheeled car which is composed of inexpensive and commonplace parts, and the performance of the assembled 4-wheeled car is sensitive to its assembly arrangement. And then we implemented this program with the handicraft kit to the university freshmen, and verified its effectiveness, and report the results of the program.
