Summer Musical Set Moving Robots

[math311]

We have been working daily for the past two weeks, and some of the most fun has been when we got the entire cast and crew together in the auditorium, and announced that we were going to build some robotic set, and that anything with a blinky light or wire could shock them, and that unless they were interested in losing a finger, they should avoid contact with the chains. The looks they had were priceless. To re-enforce the point we wanted to stick a fake hand in the drivetrain and drive a bot across the stage covered with fake blood. But we were informed that we could not, due to lacking sufficient supplies of fake blood!
