This is my first robot that's capable of doing two different kind of navigations : light seeking and obstacle avoidance. At first i didn't know how i would program it to do what it does in the video. So i was spending quite a while for programming the robot, but in the end i got it and that's how it is. You always have to keep on trying(A little motivational sentense).
