The Rube Goldberg competition is where different groups compete for design, etc. on a machine. The competition is named after Rube Goldberg, who drew cartoons making a simple task, such as opening a door, into a long and complicated machine.

This year's task (2005) is to make a machine that "Removes both old batteries from a two-battery flashlight, installs new batteries and turns the flashlight on." It has to have more than 20 steps.

April 15th--

The deadline is fast approaching. For the most part the machine works. We just the main component mounted and working. The claw is holding us back. To mount it it seems like we need the things done that we need the claw mounted for. It's one big loop! Let's hope all goes well the next 2 weeks.
