I honestly don't see who has time to try and "pick up" girls at robotics. I'm so busy and hyper at events that if I see someone I'm attracted to or if I'm getting along with well in conversation, I'll think "hey, maybe I should get her Facebook / number / whatever" several hours after the fact... Robotics is really the only place where I'm distracted from girls.
On the rare occasion I can't stop thinking about someone cool I just met at a comp, I just go talk to them again really, like a normal person. Don't let this dissuade you from using terrible pickup lines; after all this is one of my favorite CD threads
If you find your quotes sprinkled throughout this thread, I am happy to give advice on how to avoid that fate
