Last year my team learned the hard way not to trust team field-constructed elements either. Especially if not constructed by your own team!

At our second regional we converted our robot to be a chute-fed tote stacker, with a ramp that was meant to butt up against the chute door (yes, chute door). We built it in our pits and tested it with the wooden feeder station in the practice area. Confident that it worked, we marched out to our next match and sat by the feeder. The match started, we fed our first tote, and... it got stuck. That's when we discovered that we had built our ramp 1/2" too high.
