Some embodiments provide apparatuses and methods useful to providing control over movement of motorized transport units. In some embodiments, an apparatus providing control over movement of motorized transport units at a shopping facility comprises: a central computer system comprising: a transceiver; a control circuit; a memory coupled to the control circuit and storing computer instructions that when executed by the control circuit cause the control circuit to perform the steps of: obtain, from one or more of the communications received from the motorized transport unit, route condition information comprising information corresponding to an intended route of travel; obtain additional route condition information detected by one or more detectors external to the motorized transport unit; detect an object affecting the intended route of travel; identify an action to be taken by the motorized transport unit with respect to the detected object; and communicate one or more instructions.

An electronic component enclosure comprises an outer frame and an inner frame, with the outer and inner frames forming a plenum therebetween. A cooling facility such as an HVAC unit is fluidly coupled to the electronic component enclosure's plenum. The cooling facility is controlled by a control system configured to adjust at least one property of fluid flowing through the plenum, such as its flow rate and/or temperature. Alternatively, a cooling system can comprise a plurality of electronic component enclosures such that a control system can be configured to adjust at least one property of fluid flowing through each electronic component enclosure's respective plenum.

According to one embodiment, an information collecting apparatus includes a plurality of tag readers disposed on a mobile apparatus, each respective tag reader being configured to detect a wireless tag attached to an article that is within a detection range of the respective tag reader, a movement controller configured to control movement of the mobile apparatus within a search area along a plurality of routes, each route enclosing a different segment region of the search area, and a data processor configured to acquire tag detection information of the wireless tag during a time in which the mobile apparatus is moving in a particular route enclosing each segment region, aggregate the number of times for which the wireless tag is detected, and identify a particular segment region in which the wireless tag is present based on the aggregated number of times for which the wireless tag is detected.

Drifting karts in accordance with embodiments of the invention are described that include a front wheel drive train and rear caster wheels that can be dynamically engaged to induce and control drift during a turn. One embodiment of the invention includes a chassis to which a steering column is mounted, where the steering column includes at least one front steerable wheel configured to be driven by an electric motor, a battery housing mounted to the chassis, where the battery housing contains a controller and at least one battery, wiring configured to provide power from the at least one battery to the electric motor, two caster wheels mounted to the chassis, where each caster wheel is configured to rotate around a rotational axis and swivel around a swivel axis, and a hand lever configured to dynamically engage the caster wheels to induce and control drift during a turn.

Some embodiments include apparatuses providing control over movement of motorized transport units at a retail facility, comprising: multiple self-propelled motorized transport units; a wireless communication network; and a central computer system, wherein the central computer system comprises: a transceiver; a control circuit; and a memory storing computer instructions that when executed cause the control circuit to: receive an override command, from a worker associated with the retail facility, to cause a first motorized transport unit of the multiple motorized transport units to implement one or more actions; confirm a valid authorization of the worker to override one or more operating limits of the first motorized transport unit; and override the one or more operating limits and communicate one or more instructions to the first motorized transport unit configured to cause the first motorized transport unit to implement the one or more actions in accordance with the override command.

Drifting karts in accordance with embodiments of the invention are described that include a front wheel drive train and rear caster wheels that can be dynamically engaged to induce and control drift during a turn. One embodiment of the invention includes a chassis to which a steering column is mounted, where the steering column includes at least one front steerable wheel configured to be driven by an electric motor, a battery housing mounted to the chassis, where the battery housing contains a controller and at least one battery, wiring configured to provide power from the at least one battery to the electric motor, two caster wheels mounted to the chassis, where each caster wheel is configured to rotate around a rotational axis and swivel around a swivel axis, and a hand lever configured to dynamically engage the caster wheels to induce and control drift during a turn.

An electric golf trolley Includes an electric actuator includes a motor controller, two planetary gear reduction motors connected to the motor controller and mounted on two rear wheel modules in a one-to-one correspondence manner, and a power supply connected to the motor controller. A connecting-rod link mechanism is disposed between an upper frame module, a lower frame module and the two rear wheel modules. When folded towards the lower frame module, the upper frame module drives the rear wheel modules through the connecting-rod link mechanism to be folded synchronously. The motor controller is mounted on the upper or lower frame module. The power supply is mounted on the upper or lower frame module. The rear wheel modules are separately driven by the planetary gear reduction motors, so a spindle rotating synchronously along with the rear wheel modules does not need to be additionally disposed between the rear wheel modules.

Systems, apparatuses, and methods are provided herein for sorting items discarded in a shopping facility. A system for sorting discarded items comprises a motorized transport unit configured to travel around discarded items placed in a sorting area in the shopping facility, the motorized transport unit comprises a sensor device and an item mover device, an item characterization database storing characteristics corresponding to a plurality of items likely to be found in the shopping facility, and a central computer system. The central computer system is configured to receive data from the sensor device on the motorized transport unit, determine an item characteristic of an item among the discarded items in the sorting area, determine a sorting category of the item from a plurality of predefined categories, and cause the motorized transport unit to move the item, with the item mover device, from the sorting area into a category area.

Some embodiments provide methods and systems of monitoring trash cans. A central computer system of a shopping facility identifies a first motorized transport unit and a second motorized transport unit; communicates routing instructions based on a mapping of the shopping facility to each of the first and second motorized transport units directing the first and second motorized transport units to a trash can receptacle, wherein the second motorized transport unit transports a replacement second trash can; communicates trash can removal instruction to the first motorized transport unit to cause the first motorized transport unit to remove the first trash can from the trash can receptacle; and communicates a trash can replacement instruction to the second motorized transport unit to cause the second motorized transport unit to place the second trash can into the trash can receptacle in place of the first trash can.
