Now, the freshmen have completed their final choice of major, but many students who choose robotics engineering and electronic information are confused about their major. We hope that through this activity, we can have a deeper understanding of robotics and their major, and learn more knowledge from the cheerful game atmosphere. So far, all members of the project Department of g-master robot community have a certain understanding of all the basic functions of logo ev3, and have been able to complete independent assembly and operation. Can undertake the teaching task of this activity.
