Goals from Daniel Powell and Ryan Lowe - either side of Franck Moussa's equaliser - had put the Dons in charge at half-time before Stephen Elliott's double condemned the hosts to a third defeat in four games.
Robins was full of praise for the contributions of the likes of Elliott, who starred on a rare start for the club this season in place of suspended top scorer David McGoldrick.
He said: "We were outstanding in every department. We have a couple of players out who have contributed so much over the past few months and it was important that we got to see the good side of the players that have been on the sidelines.
"Stevie Elliott has come in, got his two goals and he's absolutely thoroughly deserved it because he's kept his head down and worked hard.
"You talk to them and you say it's a squad game and when people get their chances they've got to be ready, and he epitomises that spirit that's there at the moment.
"The two goals he scored were outstanding and Franck's goal was out of the top drawer. Second half we were excellent, we spoke about it at half-time and then they've come out and delivered a performance that's among the best this season."
Powell put the Dons ahead after 15 minutes when he cut in from the right and drilled a fine left-footed shot inside the far post.
Moussa produced a superb solo goal to equalise for Coventry before Lowe restored the Dons' lead seven minutes before the break with a fine angled shot.
But City striker Elliott scored twice in three minutes shortly after half-time to turn the match on its head, first when he nodded in Gary McSheffrey's cross from close range and then when he fired low past David Martin.
