(...) 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 Steve, Thank you very much for your put! (...) Can't take the credit. I got the idea from the Sato book, instead of 4 legs, I thought the 6 legs are much more stable. (...)

What if you were to make a small platform for the light sensors in between the legs that rest on the ground and has a slide somewhere so when the robot moves up or down it stays touching the ground. ----- Original Message ----- From: "Elizabeth (...)

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. Middle leg on each side is connected on an 8-tooth gear and attach an 40-tooth gear. This (...) (22 years ago, 19-May-04, to lugnet.robotics.rcx.legos, lugnet.robotics.rcx.robolab)
