(...) Your approach is pretty common. As it turns out, you can (should) remove the wait time, also. Many people think they need to tell the robot how long to turn, or how long to go forward.

Hi, I built this 6-legs bug for a black line tracking test. The construction: It is a walker with 2 motors, one for 3-left-legs, another one for the right.
