The 28-year-old has agreed a deal that will keep him at Brunton Park until 2015.
"Speaking to the gaffer (Greg Abbott) and hearing his direction and enthusiasm made my mind up," Robson told BBC Radio Cumbria.
"When you're happy at a place it's difficult to leave. I couldn't have anticipated it going so well."
Robson has made 176 appearances for Carlisle since joining the club from Hartlepool United in 2009.
