Robins' men were hampered by a 17-point deduction at the start of the last campaign, but they will start on a level playing field when the new season kicks off on Saturday.
The Millers have lost prized-asset Reuben Reid to West Brom, but Robins is confident they can challenge for a place in League One.
He told the Sheffield Star: "We have a smaller squad but it is a strong one and the players in it are good enough for us to really push and have a right go.
"If we need to add someone or bolster it then we should have the opportunity to do so."
