Robinson, who was pleased to see his side stop the rot at the Keepmoat Stadium ahead of Saturday's FA Cup fifth-round tie against in-form Barnsley, felt they deserved greater reward.
"We were the better side and deserved all three points," he said. "But it shows what sort of place we are in when we are disappointed to only come away with a point from a team second in the league
"The whole team worked really hard and we had two or three really good chances yet our 'keeper didn't have a shot of note to save, which says it all."
Rovers, who were without several regulars, had midfielder Martin Woods back in their starting line-up for the first time in over two months, but Robinson felt he should have walked in the second period.
"He was booked in the first half and he should have picked up a second booking in the second half but the referee bottled it," he claimed.
Rovers boss Brian Flynn, who revealed after the game that absent striker Chris Brown will be out for a minimum of four weeks with a knee ligament injury, was reasonably content despite seeing his side miss out on top spot for the first time this season - with Bournemouth's win over Crewe taking them to the summit.
"It was obviously an opportunity missed to go top but we eradicated some of the problems we showed on Saturday," Flynn said, with Doncaster having lost 2-1 at home to Walsall at the weekend.
"It was a high-octane game with a lot of physical challenges and chances at both ends. We had a game plan and we stuck to it and it was important we made some amends for the last two games.
"It's important not to lose a home game and it will prove to be a valuable point."
