An autonomous transport robot for transporting a payload, the autonomous transport robot includes a payload bed having at least one reference datum surface and at least one payload justification device, the at least one payload justification device being configured to position a payload on the payload bed in substantial contact with the at least one reference datum surface to place the payload in a predetermined position on the payload bed.

Storage material handling system

A storage fill and retrieval system includes fixed storage locations distributed in a storage space and defining at least one human pick zone having at least one collection tote location, at least one autonomous mobile robot configured for holding and transporting a tote within the storage space and having an end effector arranged for autonomous transfer of the tote between the at least one robot and a tote holding station and a collection tote location, and a storage management system communicably connected to the at least one robot and configured to associate each robot with a human pick zone, wherein the at least one robot is configured to transport the tote to the collection tote location of each associated human pick zone, and wherein each collection tote location is arranged for human picker access and defines an interface between a human picker and the at least one robot.

A method and system is disclosed for dynamically routing a material transport vehicle using traffic based parameters. A controller directed to allocate a material transport vehicle to a particular node, selects the material transport vehicle that is physically closest to the particular node. The controller calculates an optimal route by identifying the possible routes between the initial node of the material transport vehicle and the destination node, and analyzing each of the nodes within each identified route according to a metric function by calculating a metric function value for each identified route. The controller then selects the route for the material transport vehicle having the smallest metric function value. The metric function may include parameters associated with each of the nodes in the material transport system including a node-to-node distance parameter, a node crossing parameter, and the number of material transport vehicles in a queue at each node within the route. In one embodiment, the metric function is given by
