I am working on a line following and obstacle avoidance robot. The aim is to ensure robot follows a line and make stops in between tracks. This should go in a loop and operate with different types of paths.
How to create intermediate stations or stops in between line follower track?
It depends how you are detecting the track. Assuming you are using a marker tape and LED/photodetectors for an optical system you have several options;
Use a single line detector and search when the line is lost;
Use two that overlap;
Use three - one to follow the line and one each side to detect misalignment or sudden changes. (eg L right or left.)
That gives you the ability to detect a "crossroads" indicating a station.
More info please on your intended method of line detecuion and obstacle detection
