Robinson is closing in on a return to full fitness following a hamstring problem, while LuaLua is making a faster than expected recovery from an ankle injury, but this weekend's game comes too soon for either.
Midfielder Jordan Cousins remains sidelined as Ian Holloway's side look to continue their impressive form which has seen them take 13 points from their last six games.
Idrissa Sylla, Jamie Mackie and Yeni Ngbakoto are all options for Holloway, having been among the substitutes at Leeds last time out.
Rotherham will finally have loan striker Carlton Morris available as they aim to put off their impending relegation for another week.
Morris signed for the Millers on loan from Norwich on transfer deadline day but has only just arrived at the club due to a hamstring injury. He will be on the bench at Loftus Road while Dexter Blackstock is also fit after a knee problem.
The Millers' injury list remains lengthy, with Darnell Fisher, Richard Wood, Kirk Broadfoot, Richard O'Donnell, Lee Camp, Stephen Kelly and Joel Ekstrand all out.
Joe Mattock begins a two-game ban as the Millers' drop will be confirmed if they lose, Blackburn and Nottingham Forest win and Burton draw.
