A variety of vehicle-based and warehouse-based solutions are provided to increase the adaptability, utility, and efficiency of materials handling vehicles in the warehouse environment, such as a materials handling vehicle comprising a picking attachment is secured to a fork carriage assembly and comprising an X-Y-Z- positioner to engage and disengage a target tote such that movement of the picking attachment along a Z axis by the X-Y-Z- positioner is independent of movement of the fork carriage assembly along the vertical axis Z by the mast assembly and mast assembly control unit. The fork carriage assembly may comprise a mobile storage cart support platform defined by one or more cart lifting forks, and an anti-rock cart engagement mechanism configured to engage a mobile storage cart supported by the cart lifting forks.

Visual indication systems and methods are provided. A material handling vehicle includes at least a first product placement location and a second product placement location. At least one visual indicator provides a visual indication at or near the first product placement location or the second product placement location. The visual indication serves as a visual confirmation for the order picker to place a product in a specific predefined placement location.

A method of fulfilling orders and order fulfillment system includes a mobile assembly cart having a plurality of order assembly positions and a pointer assembly. The pointer assembly generates a beam and directs the beam to at least one of said assembly positions for selectively identifying at least one of the assembly positions for putting an item to or retrieving an order from each identified position. The assembly cart can be positioned with respect to the pointer assembly for the picking or putting and moved away from the pointer assembly after the picking or putting.

An order fulfillment system and method of fulfilling orders, each with at least one article, includes at least one mobile robotic unit that is capable of autonomous routing in an order fulfillment facility. A stationary robotic order-picking station with a stationary robot and vision equipment sorts articles into orders. The at least one mobile robotic unit transfers articles to or from the stationary robotic order-picking station.

A stack assist system includes a stacking surface, such as a pallet, configured to receive a plurality of packages thereon. A graphical display is configured to display a visual representation of an optimized stack of packages on the staking surface. A package position indicator may indicate the location of a package to be placed on package stack. The system may receive package data from a warehouse management system and determine an optimized stack based on numerous considered and weighted parameters related to the packages. The stack assist system may further optionally include a mobile unit to travel through a warehouse, over an optimized path, to retrieve packages intended for a stack.

Provided herein is an autonomous or semi-autonomous vehicle fleet comprising a plurality of electric autonomous vehicles for apportioned display of a media, operating autonomously and a fleet management module for coordination of the autonomous vehicle fleet. Each autonomous or semi-autonomous vehicle comprising a screen configured to display the media. Activation, deactivation, brightness modification, in combination with specific media selection enables more efficient media display.

An order-picking method includes autonomously routing a plurality of mobile robotic units in an order fulfillment facility and picking articles to or putting articles from the robotic units in the order fulfillment facility. A material-handling robotic unit that is adapted for use in an order fulfillment facility includes an autonomous mobile vehicle base and a plurality of article receptacles positioned on the base. A visual indicator associated with the receptacle facilitates picking articles to or putting articles from the robotic unit.

A system for positioning a lifting cart in an automated storage facility is described. In one example, the system includes a motorized lifting cart configured to move about a railway of a storage area. An encoder on the cart reads a property of rotation of a rotating element on the cart, and a controller may receive the property of rotation from the encoder and convert it to a rotation count of the rotating element. The rotating element may be an encoder shaft, drive shaft, and like elements. Some systems include a signal emitter or photo sensor to position the lifting cart and to facilitate providing instructions to the cart.

Provided is a method of operating a server. The method includes generating a sequence for a plurality of orders based on shipments included in each of the plurality of orders, acquiring a plurality of groups including one or more consecutive orders among the plurality of sorted orders according to the generated sequence, allocating the plurality of groups to a plurality of robots such that the groups and robots are matched one-to-one, and allocating tasks to the plurality of robots based on orders included in each group.
