Abstract: An end-of-arm tool lifts a stack of totes and ejects a lowermost tote one at a time. The tool includes fixed unloading arms on which an outgoing tote slides in response to a pusher. A pair of staging arms lift the totes above the outgoing tote to free the outgoing tote and enable the outgoing tote to slide on the unloading arms.
