We used mostly US Standard on our robot.. We tend to "borrow" stuff from various companies we work at, and since the company i work for and two of the engineers work for only use U.S. Standard sizes its easier for us to grab a few US Standard nuts or taps if we need them for the robot.

Then again we're a scrappy team and we use whatever we find laying around so if it's metric we'll figure out a way to make it work (if it dosen't fit just use a bigger hammer)
