Line follower routine basic line following routine for a tribot with 1 light sensor pointed down for following a black line.
Nanomax routine this is the code that drove the demo robot at school on 8/30/07, that accomplished 3 missions – sweeping the molecular table, tripping the self-assembling nanotube, and the molecule drop into the molecular motor. The routine uses dead-reckoning navigation, loops, light sensor feedback for line following, and bump sensor feedback to terminate the line following loop.
Dumper routine this code was used for an opening sequence of 2006/2007 missions, dirt trap dump, trip space elevator and retrieve pizza molecules. It uses forward and rear touch sensors to control precise stopping points at the dirt dump and space elevator. The robot configuration for the dirt trap used a lasso to encircle the trap, pull on it, and then the robot left the lasso on the field (you can do that – leave parts on the field) before moving on to the next mission.
