I don't write that often in here, but I simply had to share this model.
A friend and I have worked on how to introduce kids to programming from a very early age and this is our first project:
As said this is our first project in this direction and we are already tinkering with the next project, as this model have quit a few problems. The steering is not precis enough, red balls are often registered as yellow and you need two NXT models to build it!
The idea with the next model is that the students should put QR stickers on a paper. We then use a smartphone to register the QR codes. The smartphone then tell the robot how to drive based on the QR codes. The only problem is that we haven't tried to combine smartphones and mindstorms yet. Does any one here have any idea what program to use, how to start working on it or another place we might be able to find some startup help?
Part of the model builds on Robin Newmans ball sorter, found at:
