Silly Programming screw ups (funny)

[Kevin Sevcik]

Hah, I've got a story from this year that wasn't even my fault. We were debugging out feedback controlled lift in AZ, and had just rewired the feedback pot and screwed it down into the proper place. The soft limits in the code hadn't been reset yet and we hadn't verified that everything was going in the proper directions, so I had the electrical team pull the breaker for the lift as well as for the drive motors since we were testing on the floor. A match came up , so I told the electrical team to replace the drive breakers. We sent the drive team out with the robot and presumably without a functioning lift. They come back 15-20 minutes later after the match, and our coach says "Hey, the lift worked great that match."

After I recovered from my heart attack, we determined that the electrical team misheard me and replaced all of the 40 amp breakers instead of just the lift breaker.

I can't believe I forgot this one. Well, It turned out NOT to be a programming error which we initially thought it was but.
At St Louis we took the bot over to the practice field and were going to, you know, test. I reached in and turned on the robot and WHAM! The arm that we have on it SLAMS into my temple, making me go woosy for a second and I have since had major headaches (getting that taken care of).
One of our mentors swore it was a code problem even though the bot was in disabled mode through our disable switch box on our OI, and none of the joysticks were moved.
It turns out that our electrician accidentally wired a victor backwards so the arm got direct power and so when I turned it on, it went haywire.
It hurt, a lot.

One time our programming mentor accidentally inverted the autonomous code, so it went the totally opposite way.

He was standing behind the robot holding the tether when we engaged it.

He got nailed, but got out of the way in time.

Everybody laugh, cheered, and yelled things like "MR. PAWLY, SUICIDE IS NOT THE ANSWER!"
