The Small Cart Robot, after being moved into the Repair ward, was near HAN-S. He escaped from the Ward with all the other reject bots after WALL•E had freed them. The Small Cart Robot was seen again briefly with PR-T, POW-R, L-T and some other robots when EVE and WALL•E were taking the plant to the Axiom's holo detector.
