Robins said: "We've kept three clean sheets in four matches. That game at Newcastle was a freak result and David Preece is a good goalkeeper.
"His performance on Saturday helped us get a point and it could have been more if we had been better at the other end. We can take heart from that result because Crystal Palace have had a decent season."
Robins, whose side take on Nottingham Forest on Tuesday, added: "We've done well on Tuesday nights recently both at home and away.
"We want to win this one and push ourselves all the way. We're heading into the business end of the season and it's important for us to push on. I do not think we have played badly in too many matches this season and we have a good squad of players here. We want to continue that in the last few matches."
