I built a zigzag using ev3.Well,it looks really simple!But I think it is powerful enough.The camera is bad!So,the picture is not clear.

Maybe you have noticed,the light sensor is not fixed on the zigzag car,but is connected to a motor,so that the light sensor can move independently,and can direct the car to move.I probably will release the program and video in a couple of days.Who knows if it would work!
