Abstract: The course “Intelligent Robot Design and Practice”, which is provided to senior engineering students with enough mathematics and computer basics, aims to cultivate students’ ability in system design, modeling and simulation, hands-on practice, computer control, data analysis, as well as technology optimization. LEGO EV3 robot platform has various types of supporting parts, flexible and open interfaces. In consideration of the various design potential and complete functions of LEGO EV3 robot, it is suitable for practical teaching as a teaching platform. This paper introduces the three-wheel omnidirectional robot based on the platform EV3, discussing the structure, system environment, configuration scheme, motion mechanism, as well as results analysis method. The application of this platform in actual teaching process is introduced in detail.
