A battery-powered dolly in one aspect of the present disclosure includes a handle, a connector, a motor, a wheel, a detector, a rotation information acquirer and a controller. The controller stops supplying an electric power from a battery to the motor based on (i) a battery current value and/or a battery voltage value detected by the detector and (ii) a rotation information acquired by the rotation information acquirer.

A utility cart is an apparatus that allows a user to easily carry and access items which are placed inside of the utility car. The utility cart includes a carriage, a base, and a wheel assembly. The carriage further includes a plurality of elongated supports and a closed-shape frame. The plurality of elongated supports and the closed-shape frame define a funnel-like structural shape of the carriage which allows a user to easily access items which are placed inside of the utility cart. The base provides a structural foundation for the utility cart and the wheel assembly is integrated into the base. The wheel assembly provides a conveyance means which allows the utility cart to be translated along the ground or other surface.

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.
