Sunday's game will be the first time the two teams have met since the London club were relocated 60 miles north to Buckinghamshire in 2003.
The hugely-controversial move provides an intriguing back-drop for the match and Robinson admits he is filled with excitement.
He told the Milton Keynes Citizen: "It's the most unique game in English football.
"Losing is not something that crosses my mind. I'll worry about that, and the consequences of that, if it does happen. But there's not a thought process in my mind that says we're not going to win on Sunday.
"I'm just so excited about it. I understand some people aren't. But I'm doing my job. The FA Cup has drawn us together and I want to win the game."
