ET Robcon (ET software design robot contest) is a contest which aims the education of embedded software engineer. Participants compete modeling and implement technology in the development of the robot control software. The robot should run autonomously, and both the software design and the driving performance of the control are evaluated. In this paper, the contest overview and examination methodology are described. Then the results of the participants′ survey are discussed. As a result, we confirmed the improvement of modeling technology of the participants and the effect as a PBL (Project Based Learning) .
