The disclosure described herein relates to compact lift-and-steer wheel assemblies. An assembly includes a housing, a rotational assembly, a linkage, and at least one wheel. The wheel is pivotably coupled to a bracket of the rotational assembly via a wheel mount and a pivoting member. The linkage is coupled to the pivoting member of the rotational assembly via a steering member. The assembly is configured to rotate the wheel through an opening of the housing from a first position to a second position based on the linkage translating a first distance within the housing. The assembly is configured to pivot the wheel about the rotation assembly from the second position to a third position based on the linkage translating a second distance within the housing. An adjustable cantilever wheel system is configured to suspend the assembly above ground level to allow insertion at a raised height.

Provided herein is an infant wagon having improved convenience of use, wherein the infant wagon includes a front frame, a rear frame, a support frame, side frames, a front handle frame, and a rear handle frame, and is configured such that the axial distance between front wheels and rear wheels thereof is reduced, whereby it is possible to reduce the burden applied to the arms of a caregiver when the infant wagon is moved or when the direction of the infant wagon is changed, such that the radius of rotation of the infant wagon is reduced, whereby it is possible to easily change the direction of the infant wagon, such that, when the infant wagon is pushed from the rear thereof to move the infant wagon.

A pallet moving system includes a pallet dolly puller, and a pallet dolly with a guiding structure thereon permitting and facilitating the blind engagement and disengagement of the dolly puller to the pallet. The dolly puller includes caster wheels, a handle, and at least one projecting portion configured to mateably couple with recessed portions on the underside of the pallet dolly in order that the pallet dolly may be moved and readily re-positioned even in confined spaces.

A castor supported dolly assembly, but also a dolly assembly that can be used with castors or in some cases without castors, so as to provide a new pallet assembly. The dolly assembly comprises a plurality of dolly members formed of a lightweight, disposable and/or severable material may be interconnected into interchangeable operative positions to define supporting orientations. Each dolly member includes and at least one connecting segment comprising a slot and a base. A connected orientation, of any two of the dolly members, comprises a confronting relation of the bases of engaging connecting segments and an aligned orientation of corresponding passages formed therein, so as to concurrently allow a castor to be removably received and retained in interconnecting relation to the confronting bases. Each dolly member may also include at least one supporting segment structured to receive a castor therein.

Movable containers for transporting materials using the motive power of a person are described. The containers include a recess at a bottom end thereof that may extend substantially along a width of the container. An elongated roller is partially located within the recess. The roller may extend substantially along the entirety of the recess and may have a variety of tread patterns. The container may further include more than one roller. More than one roller may be partially located within the recess of the container.

Wheel assemblies and strollers comprising wheel assemblies are provided. The wheel assembly can comprise a standard wheel and a modular wheel, where the standard wheel has a first diameter that is greater than the diameter of the modular wheel. The modular wheel can be fixedly or removably attached to the standard wheel. The stroller can comprise at least one rear wheel assembly located proximate to a rear of the base. The stroller can also comprise at last one front wheel assembly located proximate to a front of the base. The stroller can also comprise a pulling and/or steering mechanism.

The invention provides an autonomous delivery and storage system comprising a mobile robot, referred to as a porch bot, and a support vehicle, the mother bot. The porch bot features a modular shelved storage shell for transporting various products, including temperature-sensitive goods, with integrated systems for precise temperature control. It utilizes omni-wheels for versatile mobility, advanced navigation systems for real-time route optimization, and a power-sharing capability for energy efficiency. The mother bot assists with the loading, unloading, and transport of porch bots, featuring an adjustable height lift and additional temperature support systems. The system's integrated navigation, communication, and energy management technologies allow for seamless operation in diverse environments, making it suitable for both residential and commercial deliveries. This invention addresses the challenges of modern logistics by improving delivery efficiency, maintaining product integrity, and reducing operational costs through automation and advanced environmental control.

A service cart for an electric vehicle (EV) battery, comprising a lift assembly supporting a platform. The platform is configured to support the EV battery. The service cart comprises an electrically-driven hydraulic pump that is configured to extend and retract the lift assembly in order to raise and lower the platform. The service cart may comprise one or more electric wheels which may be driven by rotational force from a first electric motor, or controlled with respect to an adjustable directionality by a second electric motor.

A folding cart includes a front frame mechanism, a rear frame mechanism, a bottom frame mechanism, a first folding mechanism, and a second folding mechanism. The front frame mechanism and the rear frame mechanism are vertically and oppositely arranged, a first horizontal tube and a second horizontal tube are respectively hinged to two ends of the first folding mechanism, the first horizontal tube is hinged to a first side of the front frame mechanism, and the second horizontal tube is hinged to a first side of the rear frame mechanism; a third horizontal tube and a fourth horizontal tube are respectively hinged to two ends of the second folding mechanism, the third horizontal tube is hinged to a second side of the front frame mechanism, and the fourth horizontal tube is hinged to a second side of the rear frame mechanism.
