As an inspector the weirdest thing was probably this

They tried to use it too adjust the height of a pneumatic cylinder. We couldn't find anything illegal about it so they ended up being allowed to use it. They also wanted to mount a old school wireless security camera to the robot and carry a small CRT monitor on their driver station. Obviously we didn't allow that.
Also I'd bet 95% of teams have a incorrectly filled out BOM (or whatever they changed the acronym to). No matter how old the team is or how many times they've been on Einstein I still see teams putting KOP items on the BOM and forgetting expensive items like sensors. I usually don't make a fuss about it as it's almost impossible to go over budget and more times than not the budget is lower than what was listed on the BOM. Same goes for the pressure relief valve, you don't even know how many teams I inspected didn't set it at all or didn't even know how to set it.
As a student the worst experience I've had (and one of the reasons I like to inspect nowadays) was when a inspector spent literally an hour trying to figure out if the wire on our CIM motors from the KOP were too small because they did not list the gauge on the wire. We tried to explain that even if they were too small it would be illegal to modify them to no avail. I understand simple mistakes but this was just silly.
