Building robots itself is supposed to be frustrating, but fun at the same time. But i have little annoyances from time to time.
So, our drive coupler needed some tapped holes for set screws. So as a mentor from outside the area the team is in, I requested that the school's metals teacher to leave out a 10-32 tap for us. they left out a tap and die set which was awesome. except, no 10-32 tap in there. everything else, but that one.
so we went to a hardware store and bought one, since i couldnt just run home and get mine before the night was over.
Also, the school has 2 mills and 2 drill pressed, but different ones are down or have "do not touch" signs with metals projects in there and it sets us behind and just annoys me a little.
other than that...not anything super bad this year. just the minor frustrations. knock on wood.
