Lego EV3 Lane Following

This is the fifth class. Today we are revisiting the color sensor. We build 3 projects, and practice good coding habit- always make comments and notes for yourself or someone going to read about your code. The first project is stop at the red light. The second project add one more function to the first one. It stop at the red light, and go at the green light. The third project is a bang-bang line following robot. “Bang-bang” means if the robot see itself going too close to the black line, it will make big turn to the right, “bang”. If it is too far away from the black line, it will make big turn to the left, “bang”. That is the name come from. All students tested their robot on the track. That is fun time. Next week, we are going to implement cruise control to the robot, that means we can change the robot running speed. We can test on different map. Thanks everyone for help clean up the room.
