pic: Game hint

[s_forbes]

Well, obviously there are going to be four different game pieces: boxes, balls, tetrahedrons, and some of these. They are each placed into four starting zones randomly after the teams place their robots. In order to know what piece your dealing with in auto mode, you have to read the signal transmitted by each piece's starting zone. After you pick them up, you have to stick them in a gigantic cube in the center of the field that has holes in the shape of each game piece (you know, like that toy you had when you were a kid...)

It's so obvious.
