Abstract
The present application discloses a robotic stack mover system, and a method and a computer system for controlling the robotic stack mover system. The robotic stack mover system includes a driving unit comprising a motor, a drive chain, a tensioning unit that enforces tension of the drive chain, and a guide rail traversing a distance between the driving unit and the tensioning unit. The motor is operatively coupled to the drive chain, and the motor is configured to drive the drive chain when the motor is driven. The guide rail comprises or supports the drive chain. The driving chain comprises a set of pusher units. The pusher units are respectively configured to engage one or more vehicles inserted to the system, and to cause one or more vehicles to traverse a path having a same direction as a longitudinal direction of the guide rail when the driving chain is driven.
