Today we were building Lego Mind storm. I was with Gianni and we completed it. Everyone else got to pages 30 to 55 but there were 71 pages in the instruction manual. It has a light sensor and a line sensor so it will follow a line. It also has a swinging arm. The robot is programmed so it uses the light sensor to check the colour of the ball if it is red it will hit the ball if it is blue it will not hit it.
