College of engineering, Chubu university has started the class of “Problem-Based Learning” since 2004. It is designed as an introductory class for the freshmen in the engineering department, where robot making is the main objective. Students can study several fields of technology through the process of robot making. In this process, students who belong to different departments cooperate to solve a given theme by means of Problem-Based Learning. Two kinds of robot competition are held. One is robot soccer and the other is obstacle race. Students try to solve those subjects by the team organized for the class consisting of six members. The Problem-Based Learning is opened as an intensive class during summer vacation. Before the intensive robotic class, an orientation and classes about mechanism and 3D CAD are organized for preparation. During intensive session, classes and exercises are enforced about manufacturing, electronics and software development. In the fifth day of the intensive class, the robot competitions are enforced and in the final day students make a presentation about their lessons. The results of questionnaire survey about the class, which was evaluated by students, were investigated and concluded the class by successfully enforcing knowledge of robotics among the students.
