Welcome to the Lego Mindstorm EV3 robot programming challenge. The first class, we built a two wheel tank drive robot for the future class. We also build a color reader robot that can scan the color, then read out for you forever. Kids are excited about. Everyone tested their robot with rubik’s cube. The science behind it are loop, switch and color sensor. Next week we will explore the other sensor’s from lego. All students also helped to cleanup the classroom.
