"They have an unbelievable history - and have had a big fall from grace. In many ways there are similarities between the two clubs, we're both trying to build for the future.
"But we're going into the match with loads of confidence. It's another opportunity to test ourselves. We lost to Grimsby on penalties at this stage of the competition last season, so it would be nice to go further this year."
After Saturday's win over Grimsby in the league put the Millers into plus points, Robbo added: "We've done exceptionally well, but there's still a long way to go. To overcome our points deficit is a good achievement, but the aim is to avoid relegation.
"If we were to get to a point where we're safe, then obviously we'd have to re-assess our aims, but staying up is the priority."
