Despite winning easily, the Dons still needed a favour from Colchester and their late winner against Preston ensured they went up automatically and avoided the lottery that is the play-offs.
They also finished the season with 101 goals in League One as they ensured second-tier football at stadiummk for the first time ever.
Robinson said: “It means so much to all the players – even the loan players, you can see them all jumping up and down.
“It’s just an amazing day and we’ll never, ever forget this.
“I’m just going to take this all in and try to remember this forever and I don’t want to wake up tomorrow and find out it’s all a dream.
“The players today have been sensational and I’ve seen some special times here and this is up there with all of them.
“This is the best day in our history and hopefully now we can move on to bigger and better things as a group.
“When we found out Colchester had missed a penalty there was big lull and all of a sudden we became nervy and went backwards a little bit.
“Then all of a sudden we found out they had scored and the fans were magnificent, the players were magnificent.”
MK Dons were ahead after just six minutes when Carl Baker lashed in from 25 yards and after Dean Lewington bent in a free kick, Darren Potter’s volley ended the match as a contest.
Will Grigg got in on the act by nodding in Baker’s cross and although Jordan Spence’s own goal pulled one back for Yeovil, Lewington then finished the rout.
Yeovil boss Paul Sturrock said: “I’m really disappointed and I’m sorry to the fans who travelled a great distance.
“They are a very good team and it showed that when we made a few changes at the back.
“The players will find out their future and starting Friday morning everyone will know their fate.
“I will hold a press conference after that because I’m a great believer that the fans have got to be kept in the know, I won’t be hiding anything.
“There is a lot of work to be done, a lot of players to be found.
“Restructuring starts now. Sorry to everyone involved at the club, this leaves a bad taste in their mouths.
“There’s three of four teams who have under-achieved in the last season.
“We can’t flash the cash but need to bring in solid professionals who can play as a team and I know we can build a decent team.”
