Will the robot need to know when and where the starting line (and therefore stopping line) be located? Or will the robot simply need to carren he course following the line? What constitutes a robot leaving the line? Does that mean that the entire robot goes off track? I could see my robot infrared eye leaving the line, but having a search program to help it find the line again. Would this be allowed as long as the robot doesn't leave the track? Also, if the robot should get turned around and travel in the opposite direction, will any three complete revolutions around the track count? Is there a specific direction that the robots need to travel, i.e. clockwise or counterclockwise? Todd

I'll use a thin red line, which your light sensor probably won't be able to detect. But us humans can see it easily (...) (21 years ago, 18-Jan-04, to lugnet.robotics.events)
