A drive unit includes a support frame, a drive wheel and a prime mover. The support frame is disposed to be pivotable about a pivot axis. The drive wheel is supported by the support frame. The prime mover is supported by the support frame. The prime mover drives the drive wheel. The support frame and at least one member form a pivot unit. The at least one member pivots together with the support frame. The pivot unit has a center of gravity disposed on the opposite side of the pivot axis with respect to the drive wheel.

In the specification and drawings an accessory cart is described and shown with a base, a housing element that is connected to the base and extends upward from the base, and a platform, which is connected to the housing element with the height of the platform being automatically adjustable.

A foldable wagon with steerable front wheels and foldable seats is disclosed. The wagon has a frame having a first end assembly and an opposing second end assembly, a floor assembly and 4 wheels. The wagon also has seat assemblies comprising a first seat, a front support, and a rear support, wherein the front support for the seat is pivotally connected to a second end of the first seat and pivotally connected to the wagon frame, and wherein the rear support for the first seat is pivotally connected adjacent a first end of the first seat and pivotally connected to the end assembly. The seat is positionable in a use position such that the seat is transverse to the end assembly, and a storage position such that the seat is adjacent and generally parallel to the end assembly.

An apparatus is for locking a caster wheel in a steering position about a steering axis. The apparatus comprises a base member; a lever arm; and an engagement member. The lever arm is movable with respect to the base member into and between an engaged position in which the engagement member locks the caster wheel in the steering position and a disengaged position in which the caster is steerable out of the steering position.

Methods, systems, and machine readable medium are provided for autonomous item identification in an environment including a mobile computational device and a container. One or more sensors are disposed at the container to sense a selected item being placed in the container. In response to sensing the selected item being placed in the container, a location of the container is determined using a positioning system. One or more physical characteristics of the selected item is sensed via the one or more sensors at the container. A set of stored characteristics is retrieved from a database for available items proximate to the location of the container. An identification code for the selected item is identified based on a comparison of the one or more physical characteristics of the selected item with the stored characteristics retrieved from the database of the available items based on the location of the container.

A smart self-driving system includes a body, such as a piece of luggage, supported by a plurality of wheel assemblies. At least one wheel assemblies includes a wheel rotating motor configured to rotate a wheel of the wheel assembly to move the luggage in a given direction. At least one wheel assemblies includes a wheel orientation sensor configured to measure the orientation of the wheel. At least one wheel assembly includes a wheel orientation motor configured to orient the wheel in the given direction. The smart self-driving system is configured to move in forward direction that is different than a head direction of the body.

A wheel barrow that includes a three-wheel design and a secondary handle so that almost any single user, such as a disabled military veteran, can utilize the wheel barrow compared to traditional wheel barrows. The wheel barrow includes an A-frame, a first front wheel, a second front wheel, a rear wheel, a barrow receptacle, a clevis, and a handle bar. The A-frame is the main structural body of the wheel barrow. The first front wheel and the second front wheel provide a primary conveyance means for the wheel barrow. The rear wheel provides a secondary conveyance means for the wheel barrow and allows the wheel barrow to stand upright without the aid of the user. The barrow receptacle provides a storage means to carry material. The clevis allows the user to change directions when utilizing the wheel barrow. The handle bar provides an efficient leverage means.
