Well, here are some little movies.
They're in wmv format, so you'll need to be using windows media player. Sorry about that. I would have use mpg format, but I wanted to get them up here quite quickly.
I must apologise for the terrible quality! But they were a rush job. They're very compressed - beleive me the originals weren't much better quality.
Initialising (lid off)
The robot positions itself to the top rightmost position. It does this a lot, as it uses the touch sensors rather than the rotation sensors - recalibrating its position.
Scanning
The robot scans the list of valid moves, checking each starting position. When it detects that a pawn that should be on D2 is no longer there, it looks first at D3 and then at D4 where it finds the pawn. It realises I've played D2-D4. It's difficult to make out, I know, but you can just about see the lightsensor beneath the pieces.
Moving
The robot decides on its move. It needs to move the knight from behind the pawns (B8-C6). To do this, it has to first move the pawns out of the way. You might notice the silght waggle of the magnet at the end of the move to ensure the piece is centred in its destination square. You might also notice that it's not the zippiest of robots :)
