Like Eric said, on 1675 we mainly name as an image/internal/pride thing.
They were all mostly UPS puns, but In our 10th year (2014) we wanted to reinvigorate our "superhero team" image and have been naming our competition/practice bots after superheros/their real names since.
2005: Super Uper
2006: Super Uper Mk 2 / Holey Ghost (The robot had a lot of speedholed polycarb...)
2007: Super Uper Mk 3 / Sky Crane
2008: Mach 1675 (Like Speed Racer's Mach 5)
2009: Nom-V (our intake belt eventually had big chevrons)
2010: Uptimus Prime 6 (6th bot, and kicker mechanism sounded like a transformer while reloading)
2011: Uptisaurus Rex (roller claw looked like a dinosaur head)
2012: Uptius Erving (named after
Dr. J)
2013: Upollo's Chariot
2014:
Professor X (comp) / Charles Xavier (practice) - 10th year (X) plus the name sounded cool.
2015:
Atlas (comp) / Erik Josten (practice) - Lifting things I guess, and he was from Milwaukee
2015:
The Punisher (comp) / Frank Castle (practice) - His last name is Castle! Also we got to put sweet skulls on our claw.
