This is a simulation of a LINE FOLLOWER robot (LEGO Mindstorms or something similar). You can drive the robot around using UP, DOWN, LEFT, RIGHT. If you press the AUTO button it will toggle auto on or off. When AUTO is ON the robot will attempt to follow the black line. It can't do it at every speed - try a slower speed if the robot misses the track often. Press RESET to reset the robot to the lower left and turn AUTO off. Press TRACK to change the track. Press the blue arrows around SPEED readout to change speed up or down.
