Oh Japan, never cease to amuse me. It kinda reminds me of a internet thing they have called 'Pitagoras Switch' where people do this kind of stuff with carton, books, cups, etc.

I tried this before in school. It's not this complex, but at least the basic. The programming part is probably the hardest part. BTW extra info the black tape on the ground is for the sensor so it knows which way it's going.
