A system for mounting a stowed component on a self-propelled cart, comprising: the self-propelled cart comprising: a body having a top, bottom, front end, rear end, left side, and right side, and further comprising: a battery compartment, and a platform; a battery housed in the battery compartment; a controller; four arms, each pivotably attached at a first end to the body; four wheels, each connected to a second end of one of the four arms; four arm actuators, each configured to pivot one of the four arms such that each wheel can be moved closer to or further away from the body; and at least two motors, each configured to rotate one wheel and each independently controlled by the controller, whereby the controller can move the cart; at least one sensor for determining the position of the component to be mounted on the cart; wherein the controller can adjust the height of the cart by pivoting one or more of the four arm actuators and control the yaw of the cart by rotating one or more of the wheels; and wherein the cart is configured to approach a location of a component and adjust its orientation to compliment an orientation of the component to thereby facilitate mounting of the component on the cart is disclosed.

A self-docking, motorized cart, comprising: a body comprising a battery compartment and a platform; a battery housed in the battery compartment; a cart docking attachment arm; a controller; four arms, each pivotably attached at a first end to the body; four wheels, each connected to a second end of one of the four arms; four arm actuators, each configured to pivot one of the four arms such that each wheel can be moved closer to or further away from the body; wherein the controller adjusts the height of the cart by pivoting one or more of the four arms; and at least two motors, each configured to rotate one of the four wheels, each independently controlled by the controller, whereby the controller can move the cart and control the yaw of the cart by rotating one or more of the four wheels; whereby the cart can be moved into an appropriate position and orientation for connecting the docking arm attachment to a docking station by the controller selectively pivoting the arms and rotating the wheels; and wherein the docking attachment arm comprises connections for electricity or data is disclosed.

A motorized cart assembly includes a cart that has a basket, a collapsible frame and a plurality of wheels. The basket has a height that is greater than a width of the basket to accommodate tent poles and a tent. The frame includes a pole support for insertably receiving a respective one of the tent poles to vertically orient the respective tent pole. A drive unit is coupled to the cart and the drive unit is in mechanical communication with respective ones of the wheels. The drive unit rotates the respective wheels when the drive unit is turned on thereby facilitating the cart to be self propelled. The drive unit is in wireless communication with a personal electronic device for remotely controlling the drive unit.

A child stroller apparatus includes a stroller frame, a connecting mount provided on the stroller frame and having a first coupling portion, and an adapter suitable to receive the installation of a detachable component. The adapter is installable on and detachable from the first coupling portion of the connecting mount, and includes a support body having a second and a third coupling portion, the second coupling portion being connectible with the first coupling portion, and the third coupling portion being connectible with a detachable component. The first coupling portion of the connecting mount is adapted to receive the installation of the adapter and a detachable component, and the arrangement of the adapter on the connecting mount allows the installation of a detachable component on the third coupling portion of the adapter at a mount position that differs from a mount position provided by the connecting mount.

The disclosure is the only product of its kind that enables users to simply organize food, gear, materials, tools and other items in one easy to access location.
