Their captain Dean Lewington capped it off with the winner four minutes into stoppage time to revive the Dons play-off hopes and move them to within three points of sixth-placed Peterborough.
Robinson, whose assistant Gary Waddock was appointed Oxford manager in the morning said: "They keep pulling things out the bag and I can't ask any more of them.
"I'm running short of players and staff and we still keep winning!
"In the first half we struggled to get out and our work ethic wasn't great.
"I know I've made two changes and I don't want anyone to make Izale McLeod to be a made a scapegoat because I could have changed any of them.
"I told the ones who stayed on that they were lucky to stay on and the subs who came on made a massive difference and the effort of the players second half was magnificent.
"On the back of that I want to thank Gary Waddock as well who has been an unbelievable person for me to lean on and a really good assistant.
"I like seeing people progress and I wish him all the luck in the world."
