Abstract: The present application discloses a robotic modular stack mover system, and a method and a computer system for controlling the robotic modular pusher system. The robotic modular stack mover system includes a first stack mover system configured to cause a vehicle to traverse a first path and a second stack mover system configured to cause the vehicle to traverse a second path. The first stack mover system moves the vehicle along the first path from a source location to a first end location. The vehicle is retrieved from the first end location and the second mover system moves the vehicle along the second path to a destination location.

Abstract: The present application discloses a robotic stack pusher system, and a method and a computer system for controlling the robotic stack pusher system. The robotic stack pusher system includes an actuation device and a plurality of pusher structures that are substantially planar. At least one of the plurality of pusher structures is nested within one or more other pusher structures of the plurality of pusher structures. The actuation device is the actuation device is operatively coupled to at least one of the plurality of pusher structures. The actuation device is configured to actuate a position of the plurality of pusher structures between a retracted state and an extended state in response to a control signal. Actuation of the actuation device causes the one of the plurality of structures that is nested to extend telescopically with sufficient force and to controllably push a payload

Abstract: The present application discloses a robotic control system, and a method and a computer system for controlling a robot. The robotic control system includes a memory and one or more processors coupled to the memory. The memory is configured to store configured to store a model of a robot having a plurality of axes of control including at least a linear axis and one or more rotational axes. The one or more processors are configured to use the model to control the robot to perform a task, including by sending to the robot a set of control signals to cause the robot to move with respect to two or more of said axes of control including at least the linear axis.

Abstract: The present application discloses a mechanism to adjust backlash in a rack and pinion powertrain assembly. The mechanism to adjust backlash includes a mounting frame having an opening defined therein to receive an operative end of a drive assembly, a shoulder fastener positioned through a first complementary set of holes at a first end of a mounting flange to movably couple the mounting flange to the mounting frame, the fastener being fastened in a manner such that the mounting flange and drive assembly have freedom to pivot about a longitudinal axis of the first complementary set of holes, and an adjustable length coupling device having a first end coupled mechanically to the mounting plate and a second end coupled mechanically to the mounting flange at a location substantially opposite the first end of the mounting flange.

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.
