Our naming trend for the past couple years has been starting with a letter to eventually spell out DRAGON (as in the Mech Tech Dragons). So far we have:
Dante
Redemption
Ahab
Geoffrey
Orion
Nidhoggr
This year's robot,
Nidhoggr (pronounced Nid-Hog), is a dragon who eats the World Tree in Norse mythology.
Not sure what we'll do next year though, since this trend's ending this year!
