Abstract
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.
Claims18
An autonomous luggage cart comprising:
- (i) a floor having front-to-back length of 32 to 42 inches inclusive and side-to-side width of 18 to 24 inches inclusive;
- (ii) a bumper surrounding a perimeter of said floor;
- (iii) at least one riser pole arrayed upon said floor and extending upward from said floor from at least two points;
- (iv) a bi-directional housing mounted near a top of said riser poles;
- (v) a multi-directional housing mounted above said bi-directional housing;
- (vi) an underside housing mounted on an underside of said floor;
- (vii) a throttle handle mounted on said floor, adapted to allow manual control of movement;
- (viii) a throttle brake mounted on said throttle handle, adapted to stop movement;
- (ix) a front tow hitch mounted at a front of said floor, adapted to extend from and withdraw toward said floor and said bumper;
- (x) a rear tow hitch mounted at a rear of said floor, adapted to extend from and withdraw toward said floor and said bumper;
- (xi) a pair of front lights mounted at the front of said floor and said bumper;
- (xii) a pair of rear lights mounted at the rear of said floor and said bumper;
- (xiii) a plurality of surround lights mounted at the perimeter of said floor and said bumper;
- (xiv) a display-input unit mounted upon a said riser pole, adapted to display information and facilitate input of information;
- (xv) a pair of rear wheels mounted below said floor;
- (xvi) a pair of rear wheel motors, adapted to drive said rear wheels using electrical power;
- (xvii) a pair of front wheels mounted below said floor, adapted for steering;
- (xviii) a high-capacity battery mounted below said floor within said underside housing, adapted to provide electrical power for driving said rear wheel motors;
- (xix) a battery charge manager mounted below said floor within said underside housing, adapted to charging and discharging of said high-capacity battery;
- (xx) four corner sensors, each mounted at a corner of said floor and said bumper, adapted to sense proximity, location, and size of objects;
- (xxi) two tow-hitch sensors, mounted adjacent to said front tow hitch and said rear tow hitch, adapted to send and receive signals each from the other;
- (xxii) a camera-sensor package mounted within said multi-directional housing, adapted to sense information from a wide field of coverage;
- (xxiii) a plurality of directional sensors mounted within said bi-directional housing, adapted to sense information from narrow fields of coverage from front and rear directions;
- (xxiv) at least one RFID unit mounted on a said riser pole, adapted to send information to RFID readers;
- (xxv) a controller unit mounted below said floor within said underside housing, adapted to receive the information from said corner sensors, tow-hitch sensors, camera-sensor package, and directional sensors, to analyze such the information applying machine-learning and artificial-intelligence methods, and to control operations of said autonomous luggage cart;
- (xxvi) a communications unit adapted to send and receive wireless signals to provide communications with external entities;
- and
- (xxvii) a remote unit adapted to communicate wirelessly with said communications unit.
