Ya it is very stressful in the operator station.
I am a freshman and being a robot driver, I do get very nervous before the match. I was actually picked driver at a meeting that I didn't attend because I had been really busy with a project. The first match I competed in was at the regional and it was the first match our robot played in. I had been really stressed out because if anything happened to the robot or if we didn't win, chances are they would've blamed it on me. In that match, we were the only scoring team on our alliance. I felt more relieved after the match because I realized it wouldn't have been that stressful after realizing how well I actually did.
It was a good experience, but then at another event the day after, I was driving the robot...and I wasn't as good as I had been the day before...and well...it just didn't really go so well
...but is it normal to have like, an offday?
