Robbie then had a short spell at St Patrick's Athletic on his return before joining Bray Wanderers in time for the 2001/02 season. He made a handful of appearances at the club when Paul Doolin offered him regular first team football at UCD and so Doyle was on his way again. He scored on his debut for UCD on the first day of the 2002/03 season against Bohemians and his performances that season impressed Stephen Kenny enough to offer him a move to Bohemians at the end of the season.
He made a decent start to life at Dalymount and played in all of Bohs' four 2003–04 UEFA Champions League qualifiers and in mid 2004, he returned once again to St Patrick's Athletic. He has since played for Bray Wanderers and Macclesfield Town.
