A method for moving one or more mobile drive units within a workspace includes receiving, from a first mobile drive unit, a reservation request requesting use of a first path segment to move in a first direction. The method further includes determining that a second mobile drive unit is currently located on the first path segment and determining whether the second mobile drive unit is moving in the first direction. Additionally, the method includes transmitting a reservation response indicating that the reservation request is denied, in response to determining that the second mobile drive unit is not moving in the first direction. The method also includes transmitting a reservation response indicating that the reservation request is granted, in response to determining that the second mobile drive unit is moving in the first direction.

A method and system of fault prediction in a packaging machine is disclosed. The method comprises registering data values associated with the motion of independently movable objects along a track in the packaging machine; determining a distribution of the data values; calculating a measure of central tendency of the data values in the distribution; calculating a quantified measure of a shape of the distribution; associating the measure of central tendency with said quantified measure of the shape as a coupled set of condition parameters; determining a degree of dispersion of a plurality of coupled sets of condition parameters associated with a plurality of motion cycles of the independently movable objects; and comparing the degree of dispersion with a dispersion threshold value, or determining a trend of the degree of dispersion over time, for said fault prediction.

A handling robot, a material fetching method, a material replenishing or returning method, and an intelligent warehousing system, the handling robot comprises a vertical bracket (19); a pallet (22) for storing a material box; and a handling system installed to the vertical bracket (19), where the pallet (22) is installed to the handling system, and the handling system is used for fetching a material box from one of a warehouse shelf (24) and the pallet (22), storing it onto the other, and/or fetching out a material from a material box stored on the pallet (22). With the configuration of the handling system, a material can be fetched out from a material box stored on the pallet, and after the material is fetched out, the material box is placed back onto the warehouse shelf, such manner of material fetching is flexible, and has high efficiency.

A conveyor system includes: a pick conveyor defining a picking area for a bulk flow of parcels; a place conveyor positioned downstream of the picking area; a first robot singulator and a second robot singulator, which work in parallel to transfer parcels within a picking area of the pick conveyor to the place conveyor; and a vision and control subsystem that communicates instructions to control operation of some or all of the foregoing components. The vision and control subsystem includes a target camera for acquiring one or more images of the picking area, which are processed within the system to determine the location of parcels positioned within the picking area. The vision and control subsystem can execute one or more routines or subroutines to reduce system downtime associated with image acquisition and processing, parcel transfer to the place conveyor, and/or parcel delivery to the picking area.

A method of palletizing non-uniform objects comprises using shuttle robots controlled by a monitoring and control system (190) to control trolleys, each of which carries an object, from a feed point (101) to a palletizing station (140) via a device (120) for determining the morphologies of the objects so as to characterize the outside shapes of all of the objects forming a batch before the start of the operation of stowing the objects on the pallet, so as to calculate a stowage plan that optimizes stowage of the batch on a pallet (150).

A system for singulating objects includes a bin for receiving a collection of objects, a robotic manipulator for grasping objects from the bin, a scale for measuring a weight of the grasped objects, and a computer system for comparing measured weights to acceptable weight ranges to detect double picks. Methods include determining acceptable weight ranges by weighing a plurality of objects.

A method of manipulating boxes includes receiving a minimum box size for a plurality of boxes varying in size located in a walled container. The method also includes dividing a grip area of a gripper into a plurality of zones. The method further includes locating a set of candidate boxes based on an image from a visual sensor. For each zone, the method additionally includes, determining an overlap of a respective zone with one or more neighboring boxes to the set of candidate boxes. The method also includes determining a grasp pose for a target candidate box that avoids one or more walls of the walled container. The method further includes executing the grasp pose to lift the target candidate box by the gripper where the gripper activates each zone of the plurality of zones that does not overlap a respective neighboring box to the target candidate box.

A processing system is disclosed for processing objects. The processing system includes a perception system for providing perception data regarding an object, and a primary transport system for providing transport of the object along a primary direction toward a processing location that is identified based on the perception data.
