Every year at bunnybot for us. We have all of the non senior members design and build a bot with minimal help from the senior people.
My freshmen year, I, along with a group of five other students, designed this robot with a giant snow shovel on the end of a big piston. As we were driving, I bumped the controller the wrong way (our programmer plays inverted) and tilted the show shovel down into the carpet and fired the piston at the same time. We halfway did a pole jump before getting stuck. We then proceeded to trash the tread on the wheels and burn a hole in the carpet while trying to escape. I don't think the flaming chickens were too happy with that.
And for logomotion: Using a banebots 256 to 1 transmission to move a 13 foot arm without a counterbalance. It got to the point where we were rebuilding the transmission between every match and taking apart other transmissions for the gears. Ugh. Lets just say that I can now completely reassemble and re grease a transmission in the dark in under five minutes.
