Coventry, still without a home win in the league this season, took the lead in the 34th minute when Richard Wood powered home a header from Gary McSheffrey's corner.
But they could not keep the advantage for long as Stephen Gleeson's deflected effort flew into the net. Yet after picking up their first league win of the season at the weekend, Robins is happy with the direction in which his newly-acquired side are moving.
He said: "We scored from a set-piece. The players have worked hard on those in training and it was good to see it go in.
"MK Dons are a good team and they have really good movement. We played Arsenal in the cup last week and I thought we coped better with their movement than we did here.
"We have to be happy with the point because I think that last week we would have lost that game. That is now four points we have got from the last two games, and before that we had only got three all season."
