NXT Robot programming

The light sensor flicked on the robot was off. It was our session of robotics, Daniel and I were trying to make our robot follow the lines of our light sensor sheet. It was a success, the robot completely drove around the track. Darryn took a photo of Daniel and me with our robot."Now time to blog you two" he said.
