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.
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.
Dons boss Karl Robinson said: "We didn't deserve to lose that, but it was just five minutes of madness. Their first goal was an own goal - he's headed it onto Shaun (Williams) and it's gone in the goal so it's just unlucky.
"But it was just because we didn't switch on for that five minutes - we don't generally concede many goals in that period because we normally come out all guns blazing. It was difficult that second half for me because I'm looking behind me, I'm looking on the pitch and I'm thinking what can I do?
"They say they've got no money, but when you look and (John) Fleck coming in and Elliott coming in, who has played in the Premier League, they've got tremendous strength in depth."
