Each line segment that makes up the squares can be either lit (block) or unlit (pass). If a robot
drives over a block, it will stop dead, and be removed by the arm overhead. The squares are sized
so that it will require a lot of fine coordination to get through. The operator will also need
knowledge of the current maze (since it will change daily. This is either accomplished by a partner
who will communincate where to go, or research beforehand (by using the balcony upstairs).
This puzzle is also different from the ones in the room beyond, because the operator will have to cross this maze every time he wants to do any puzzle. Other rooms will note whether or not you've passed them before, but this one is based totally on whether you've passed it since you were last put in the play pen.
