The Tykes have won their last three league matches to climb out of the relegation zone while Forest extended their winning sequence to four league matches and climbed up to seventh with victory over Newcastle on Saturday.
Robins said: "We now have another very tough game coming up at Nottingham Forest. There's competition for places here now and we do have players waiting to seize a shirt.
"But I'm expecting a very confident Nottingham Forest side who will want to carry on their own good run of wins.
"They're a good side under Billy Davies and there are very high expectations at that football club, so we will have to go there and nullify that threat.
"We want to carry on our own mini run and hopefully extend it. We want to put on a performance and I'm sure that if we can keep hold of the ball better then we will be OK."
