The present disclosure is directed to wheel-based human-powered spinning system comprising: a chassis configured to secure a user; a track surrounding said chassis; and at least one omni wheels attached to said chassis, wherein said chassis spins with unlimited range of motion, along pitch, yaw and roll axes, inside the track while supported by said at least one omni wheels, said track being independent of contact from said chassis.

An aircraft galley cart is disclosed. In embodiments, the galley cart includes two adjacent portions (e.g., left and right side) hingedly or slidably connected. The galley cart has a default configuration compatible with galley cart bays of galley structures. The galley cart may be transitioned into a narrow configuration by articulating the left-side portion relative to the right-side portion (e.g., by pivoting or rotating the left-side portion). When in the narrow configuration, the galley cart may be twice as long but half as wide, allowing passenger access through an aisle without removing the galley cart back out of the aisle and disrupting in-seat food and beverage services. The galley cart includes auxiliary casters that deploy during transition to support the main casters in keeping the galley cart balanced and mobile in the narrow configuration.

A studded wheel increases traction of a vehicle along slippery surfaces, such as a pipe. The wheel features a wheel body manufactured from a rigid material and having a tread surface. A plurality of studs are secured to the tread surface of the wheel body. The plurality of studs may be polycrystalline diamond. The plurality of studs may be secured directly to the tread surface of the wheel body, such as by brazing. The vehicle to which the wheel is attached may be an inspection vehicle with a mounted camera system fitted for surveying inaccessible areas including sewer systems and other internal piped locations.

A wheel for a non-motorized vehicle (e.g., a shopping cart) can include a housing assembly and a tread assembly. The housing assembly can be configured to sealingly house electronics or other components. The tread assembly can removably mate with the housing assembly such that the electronics or other components remain closed and/or sealed within the housing assembly when the tread assembly is mated or unmated with the housing assembly.

The present invention relates to the construction of Mecanum wheels for a robot-operated painting system. The wheels have special characteristics given the difficulties and obstacles where they will be used. They were designed to facilitate the movement of the painting system on vertical and horizontal walls and to avoid coating losses. The Mecanum wheels consist of a set of wheel covers that are used to secure the rollers. The rollers, arranged at 45° and in a cylindrical-convex shape, contain bearings passing through their central axis, and have rollers at the ends of the bearings. The magnetic base is placed between the two wheels, being at an optimal height to exert magnetic force against the surface and to be able to pass over obstacles. Mecanum wheel geometries and materials are designed to be inert to the coating.
