For the second time in succession, Rovers had contentious penalty shouts go against them as Millwall twice scored from the spot.
But as they showed against Watford earlier in the week, Rovers never gave up and battled back twice to earn a draw despite being down to ten men for more than 30 minutes of the second half.
"We feel hard done to, certainly with the first one," said Robinson on the penalty decisions.
"But that is football, decisions go for you, decisions go against you. I thought we showed a great resilience.
"It shows the togetherness, it shows the strength of the team that we have got, we never believe that we are beaten.
"We've got a great team spirit here and it is a quality that has come into our game, even with two minutes to go we still believed that we could get back into the game just like we did in midweek at Watford."
The point gained saw Rovers move eight points behind the play-off places, but with their game in hand taking place this Tuesday against Brighton & Hove Albion at Ewood Park, the Rovers keeper isn't giving up.
"Until it is mathematically impossible then the play-offs are still our aim," added the keeper.
"It has always been our aim, we are unbeaten in four now although we haven't got enough wins, but we've got three home games to come, three big games and at the end of those three games we'll see where we are at.
"But we still believe and that is where we want to be."
