In Horizon Forbidden West, Cauldrons allow players to override the machines that are within that Cauldron once they have completed it. Completing a Cauldron usually means traversing through its dungeon-like corridors and facing off against a boss at the end. The Rollerback is a part of the IOTA Overrides Cauldron.
