Trying to code Edscratch and Edison to detect an obstacle and then go around the obstacle by itself through a series of spins, turns, and backward or forward movement. I can detect the obstacle. I can calibrate most of the Edisons so that they detect the obstacle to within about an inch. I can drive around the obstacle through a series of turns (like a square) and I can resume following the line after moving past the obstacle. The obstacle is a wood block that is two inches high and six inches long. Do you have any code suggestions for going around the obstacle?
