I haven't been building that many new robots/designs lately, I've been putting more effort in to skinning the crap out of the select few robots I have been making and entering into tourneys.
That said, i'd like to introduce you to the failed four:
Not Constantinople: A rejected entry for Home and Away, I just preferred SHW-Miss America

Now some robots which I made for BB3.
Happy: The Littlest Robot: A quick robot to make, made it, shoved 2 npc fasts in it. Boring.
Memo To Human Resources: I was
SO CLOSE to entering this into BB3, but when the disc span up the whole bot would flip and I have no idea how to fix that. So it made way for Crab Jr.
Wintergreen: Treading the damage/realisticness line is annoying! I could imagine this one failing dismally in combat against rammers, so I moved on.
