A foldable cart assembly which is arranged to provide trackable transportation to a product or a person. The cart contains sensors and computer-controlled drive wheels to enable that cart assembly, when fully opened, to follow a safe path as directed by received electronic signals. That cart assembly is also tri-foldably collapsible, so as to have multiple portions pivoted into nesting configuration with one another thus containable in a minimal volume and even carried by an individual.

1. An articulably collapsible cart assembly having a lower frame, the cart assembly enabled to carry a load in an open orientation, and to be collapsed into a minimal tri-folded configuration without a load, the cart assembly comprising: a lower frame first end having a pair of free-wheeling support wheels in a spaced apart manner on an axle;a lower frame second end connected to the first end by an elongated connecting frame, the second end having a pair of wheels thereon, and wherein the elongated connecting frame has a mid-frame lower collapse axis thereon which permits the first end of the elongated frame to be folded very compactly under the lower frame second end;an upper frame arrangement connected to the lower frame, the upper frame arrangement having an uppermost collapse axis thereacross and an intermediate, transversely disposed, cart-assembly-carry, collapse axis thereacross, wherein the intermediate axis comprises a carry handle, the uppermost collapse axis and the intermediate collapse axis enabling the uppermost frame arrangement to be pivoted counter to one another towards the lower frame, to collapse the cart assembly into a hand-carryable configuration by the intermediate, cart-assembly-carry collapse axis handle. 2. The collapsible cart assembly as recited in claim 1, wherein the intermediate axis permits the cart assembly to be carried in its collapsed hand-carryable configuration. 3. The collapsible cart assembly as recited in claim 1, wherein the second end of the frame has a pair of drive wheels thereon. 4. The collapsible cart assembly as recited in claim 3, wherein each of the pair of drive wheels are empowered by an independent drive motor. 5. The collapsible cart assembly as recited in claim 3, wherein a fifth wheel is supported between the pair of drive wheels. 6. The collapsible cart assembly as recited in claim 5, wherein the fifth wheel is adjustably supported about a swivel axis. 7. The collapsible cart assembly as recited in claim 1, wherein a pair of horizontally spaced apart sensor support arms extend from the upper frame arrangement. 8. The collapsible cart assembly as recited in claim 1 wherein the lower frame and the upper frame arrangement each have a load supporting securement arrangement thereon. 9. The collapsible cart assembly as recited in claim 1, wherein an enclosure housing is supportively arranged between the drive wheels, so as to enclose control means and empowerment means therein. 10. The collapsible cart assembly as recited in claim 1, wherein the uppermost collapse axis adjustably supports a “U” shaped handle. 11. The collapsible cart assembly as recited in claim 1, wherein the cart assembly is autonomous so as to provide self-directed, self-propelled motion for a user thereof. 12. A method of collapsing a cart assembly from an open, load carrying configuration to a collapsed minimally sized, hand carryable configuration, comprising: connecting a wheeled first frame end to a wheeled second frame end by a lower pivot axis articulably disposed midway therebetween, thereby constructing an elongated lower frame arrangement;connecting an upper frame arrangement to the wheeled second end of the lower frame arrangement;dividing the upper frame arrangement into an intermediate, pivotable frame portion and a pivotably attached uppermost frame portion connected to one another by an upper pivot axis;swinging the wheeled first end of the elongated lower frame arrangement about its lower, midway-disposed, pivot axis, and into a disposition under the wheeled second frame end of the elongated lower frame;swinging the uppermost frame portion about the upper pivot axis into a nesting disposition between side portions of the intermediate pivotable frame portion;swinging the combined uppermost frame portion nested between the side portions of the intermediate pivotable frame portion and the intermediate pivotable frame portion about an intermediate cart-assembly-carry pivot axis comprising a carry handle so as to lie on top of and into close nesting orientation with the second wheeled end of the elongated lower frame portion, wherein the intermediate pivot axis thus becomes a carry handle for the cart assembly. 13. The method as recited in claim 12, wherein the wheeled second frame end has a pair of motorized wheels thereon. 14. The method as recited in claim 13, wherein the motorized wheels are individually empowered as to direction and speed by a control computer. 15. The method as recited in claim 13, wherein the cart assembly is a golf club carrying cart. 16. The method as recited in claim 14, including; arranging a sensor array on the cart so as to permit control and direction to the motorized wheels to function with autonomous cart motion for a user thereof. 17. An articulably collapsible autonomously mobile cart assembly enabled to carry a load in an open orientation, collapsable into a minimal tri-folded configuration without a load, the cart assembly comprising: an elongated lower frame having a pair of free-wheeling support wheels on an axle at one first end, and a pair of individually driven, individually instructed, multi-direction-of-rotation and individual speed controlled drive wheels at a second end of the elongated frame, the elongated frame having a transversely disposed pivot axis at a mid-point thereof to enable the elongated frame to nestably fold the first end thereof under the second end thereof;an upper frame arrangement connected to a lower connector frame, the upper frame arrangement having an uppermost collapse axis thereacross and a combination intermediate collapse axis and cart-assembly-carry-handle thereacross, the uppermost collapse axis and the intermediate collapse axis enabling the uppermost frame arrangement and the lower connector frame to be pivoted counter to one another towards the lower elongated frame, to thus enable the collapse of the cart assembly into a hand-carryable configuration. 18. The cart assembly as recited in claim 17, wherein the drive wheels have a multisensor arrangement communicating through a control unit to control the speed and direction of rotation of the drive wheels so as to control the direction of motion of the cart assembly. 19. The cart assembly as recited in claim 18, wherein the multisensory arrangement comprises a pair of spaced apart ultrasound transceivers and an RF transceiver connected to the control unit for enabling the autonomous mobility of the cart assembly.
