The robot tracks the line whether its white or black (1cm thick line). It also responds to traffic light being able to make a turn 90 degree any direction. And whenever it meets intersection without traffic light, it remembers the last 'turn' it made in previous intersection with traffic light.

Interesting thing is, i was pushed to make it within 3 weeks with only 25 USD! cheap is it??

I was later be able to move it without the microprocessor at all... but took another months or so.
