[Batman] Have any of the Robin's been adult's (over 18) while using the identity?

So, i got to wondering, have any of the Robin's lasted in the role until adulthood or further, or have they left for whatever reason before that has happened.

At least pre-Flashpoint and DCAU Dick Greyson kept on being Robin through their college years, before deciding to become Nightwing.

Kingdom Come Dick Greyson also seemed to have just evolved the Robin persona into 'Red Robin' as he became an adult.
