My friend and I were given the task of making a casing for our battery, to hold it on the robot. So we decided to make it out of very thin metal.(since it weighed next to nothing
) Only problem was that when we were driving the robot around, testing the drive shafts, the positive and negitive ends of the batteries both touched the metal at the same time!
Causing thick heavy sparks to fly 15 feet in the air!!
We got the battery out of the way before the battery fried, and scrapped the metal holder for a plastic one. The irony of this story is that me and my friend are both on the programming/
Electrical team!
This happened in the first week out of six, and not a day has past where we were not reminded about it.
