Now that we have the robots, here is your first challenge.
#1 I am going to setup a 2ft x 4ft course on a piece of butcher paper. In the four corners of the course there will be a large X. You need to program your robot to drive over each of the large X marks. You are welcome to use the black line sensor or the light sensors to accomplish this feat.
You are welcome to figure this challenge out in anyway you can but there are videos on Youtube, tutorials on the web, tutorials on the Gigglebot website
