Mar.8 Line Follower Designs

Common Designs:

• OO sequential - in for loop read light sensor and react to state
• behavior programming - an arbitrator checks in priority order defined behaviors, if their condition is true. The first behavior with a true condition is performed.  Ex: Online? go forward

Behavior programming seems to fit into the design patterns:

• observer pattern
• publish/subscribe pattern

which is used in 4DIAC network pallete as implemented by FBDK.
