While we were building our robot, the student assigned to put our chain tensioners on decided that our chains were tense enough so we didn't need them and didn't put them on. Flash forward to the middle of Friday at Los Angeles. We were up against a tough alliance, so our strategy was that we were going to bait the other team's best scorer into chasing us around the entire match, which worked for about thirty seconds until we hit a wall and threw a chain. Naturally, the opposing alliance took this opportunity to fill our trailer until no more balls could fit.
And to add insult to injury, somehow someone or something reset our CRio while we were putting the chain back on...and we didn't notice until our next match had started and we weren't connected.
The only other failure we experienced all season was our conveyor belt jamming because we left off...ONE WASHER. Oops.
