This was actually from last season, but our team found this funny (me not quite so much).
With the full court shooters, we toyed with the idea of adding a pool noodle (or whatever) to our robot to play defense. Of course the downside of that strategy is that the robot could move toward us and touch us for foul points.
We had just mounted an ultrasonic to help us with our autonomous code so that we would be the correct distance from the low goal when we tried to dump, so we set the drivetrain on a PID using something like 20" on the ultrasonic as its set point.
I had a media cart with a poster-board over the side trying to emulate a full court shooter in the corner and I was trying to push the cart fast enough toward the robot to touch it before leaving the safety zone. Then I'd try to go back to feed position.
For the most part the approach was effective-- it would back away and go back to guard position faster than the human driver could react and it was nearly impossible for me to tag the robot while the media cart was still in the safety zone.
However, the drive train didn't always move straight forward and back, and after a couple iterations, it would no longer have the ultrasonic pointing at the media cart and instead found the wall behind. Suddenly the robot was coming straight toward me , trapping me against the wall . Then my leg would step in front of the sensor and it would back away, only to charge at me again.
Members of the team who had no idea what the programmers were tying to do saw the robot attacking a mentor and thought the driver was upset or possibly the robot just simply did not like me. Apparently it was quite hilarious ...
