There seems to be no definite answer to this question. I've read that his mother liked Robins, and she called him "her little Robin" since he was born on the first day of spring (not sure if that's true). It's also said he is modeled after Robin Hood. Another one I read was that Dick mentioned his father "swooping in like a Robin" when trying to save his family.
The first Robin was Dick Grayson. The second was Jason Todd. The third is Tim Drake. The fourth was Stephanie Brown, followed by Tim Drake again. The fifth and current Robin is Damian Wayne.
Dick Grayson, the original Robin, based his costumed identity, in part, on "The Adventures of Robin Hood".
Well, actually Robin isn't even his real name, it's only his alter ego like Batman is to Bruce Wayne. Robin's real name is Dick Grayson.
he hasn't got one he's in college
Pennyworth
Batman's real name is Bruce Wayne
ive heard "Holy rusted metal batman!" from one of their old movies and then somone said that he also said "holy guacamole!" in the old tv show.
While it is never explicitly stated, there are several clues pointing to his last name being "Grayson".
