Ummmm....... from a programmers perspective, forgetting to put in stop code (aka, pwm##=127) is up there for me, beings it is VERY stupid, and easy to forget. Involved an Edubot off my coffee table, and more than a few others

For Building, ahh geez theres a bunch:
1. leaving a 7/16" wrench (are there any other sizes in FIRST????) in the hardest to reach place in the robot. that stayed there for a while
2. milling a slot in a vise...
3. tryin to drive a nail and hitting it wrong and zinging it across the room, scaring the crap outta everybody
4. Holesaws, lol Paul

Driving:
Plenty of mistakes (who doesnt make em??), but accidently climbing the 12" step instead of the 6 is the only one i can think of.

Who else has em?
