This papercraft is Big Daddy Rosie, one of the four functional types of Big Daddies in Rapture, along with the Bouncer, the Rumbler, and the Lancer, based on the first-person shooter video game BioShock, the paper models were created by Jeddychan and Roceifin. There is another Big Daddy Paper Model on the site.
Along with being assigned to protect Little Sisters, Rosies are also the supplementary mechanics and maintenance workers of Rapture. Its main weapon is a giant Rivet Gun. They are taller and slower moving than the Bouncer, making them less agile, but their long-range gun makes them just as dangerous.
