The improved mobile robot utilizes a cooperative wheeled support arrangement having a unique axle design that preferably cooperates with a base support module. A tri-axle is preferably used to support at least one omni-wheel on each axle section. Multiple omni-wheels on each section can be used for higher load applications. The tri-axle is of a fixed design and each wheel pivots on the individual axle section. Preferably, the axle sections are welded to each other.

Systems and methods are disclosed for holonomic drivetrain modules for mobile robots. In one embodiment, an example mobile robot may include a chassis, and a holonomic drivetrain module removably coupled to the chassis. The holonomic drivetrain module may include a first drive wheel having a caster angle of substantially zero, a first bearing block assembly vertically aligned with the first drive wheel, and a first steer motor coupled to the first bearing block assembly and vertically aligned with the first drive wheel.

An autonomous luggage cart system and method for transportation of objects in facilities such as hotels, condos, universities, and convention centers, providing a cart having a floor, a bumper, riser pipes, and an underside housing, wheels driven by electric motors, a high-capacity battery and a battery charge manager, front and rear tow hitches and tow-hitch sensors, corner sensors, a camera-sensor package, directional sensors, RFID units, a controller unit applying machine learning and artificial-intelligence methods to sensor data, and a communications unit and a remote unit for external communications with other systems.

A walking assist device has a frame, fixed handles, rails provided with movable handles, front wheels, rear wheels and that serve as drive wheels, drive units, a battery, and a drive control unit, and travels forward or rearward together with a user that walks while grasping the fixed handles or the movable handles. The walking assist device has an operation mode switching unit that switches between a training mode, in which a load is applied to operation of the body of the user performed as the user walks, and an assist mode in which a load on operation of the body of the user performed as the user walks is alleviated.

A power-assisted trolley includes: at least three wheels including a drive wheel; a cargo bed supported by the wheels; a handle including a grip portion extending in a left-right direction above a rear portion of the cargo bed; a motor configured to rotate the drive wheel; and a battery mounting portion configured to mount thereon a battery to supply power to the motor.

The present disclosure discloses an unmanned movable platform that includes one or more unmanned moveable vehicles that are capable of operating different modes. Under the following mode, the unmanned movable vehicles use their vision sensors to follow the operator while using other sensors to collect environmental information to smartly avoid obstacles. Under the autonomous navigation mode, the unmanned movable vehicles may autonomously navigate along a pre-stored route to complete a predefined task, such as loading or discharging an inventory.

A cart assembly adapted for manual, bicycle and/or motorized vehicle towing. Multiple frame sections are coupled to pivot between completely collapsed, partially open and completely open positions to facilitate, travel, storage and sleeping. A pair of axle plates support primary wheels to the framework and a drive axle between adjacent cross-brace arms. A handle frame section, saddle arms, truss arms, resilient spreader arms, auxiliary caster wheel, battery powered electric drive motor(s), fabric cover and/or hard cover mount to the framework. A resilient, reciprocating shock absorbing tow bar or tongue arm assembly provides flexibly resilient pieces to absorb travel shock between the cart and tow vehicle.

A system, method, and device for operations of an electrically motorized vehicle. The vehicle can utilize an electrically motorized wheel to convert a non-motorized wheeled vehicle to an electrically motorized wheeled vehicle. One system includes a server in communication with the device of each of a plurality of electrically motorized wheels, the server operable to track a position of each of the electrically motorized wheels and communicate the position thereof to a transportation network.

A rotational sliding bearing having a static part and a mobile part, each having a sub-shell with a sliding surface, each surface arranged within an angular range of max. 180° relative to the rotational axis in the direction of rotation of the bearing, and in a closed rest position, the sub-shells of all parts together form a bearing bush, the mobile part is arranged to pivot about a pivot axis for opening the bearing relative to the static part, such that a shaft mounted in the bearing is released in a release position, and the mobile part is shaped such that, based on the sliding surface position relative to the rotational axis, in the closed rest position, a translation of a shaft accommodated in the bearing is prevented transversely to the rotational axis and in the direction of the pivot axis of the mobile part or in the counter direction.

A pallet sled includes a base and a pair of tines extending from the base. A load wheel supports outer ends of each of the tines. A wheel supports the base. At least one motor is configured to drive the base wheel or at least one of the load wheels for driving the pallet sled. The motor may be a hub motor inside the base wheel or the load wheel.
