However, whilst being content with the displays and clean sheets against higher placed opponents after the 0-0 draw with Derby the week previously, Robins insists he's still looking for improvement within the squad.
Speaking to the Star, he explained: "It was a real good workout on a very warm day and we passed it better and were able to get on the ball more and use it better.
"I believe we have progressed in each of our games now and that's important and what you want to see, but I'm not reading anything too deeply into it.
"We have to continue to improve and I would like to see us move the ball a little bit quicker and have more penetration. Barnsley are a Championship side and have some strong players. Yes, there is a two division gap and they are going to have the ball and come into it but it is how we cope with it and I'm very happy to keep a clean sheet.
"The clean sheet, after one last week against Derby, is nice for confidence."
The Millers take on Stocksbridge Park Steels tonight at Bracken Moor with a 7.30pm kick off, a mixture of youth and reserve players are expected to start proceedings.
