Abstract

An automated self propelled refuse container travels from a parking or storage location to a refuse discharge location and return in response to a control unit cooperating with a tracking unit to control the direction of travel. Power is provided by an electric motor associated with each of two driving wheels rotating at the same rate and a third steering wheel provides stability and control over the direction of travel. The two driving wheels may rotate at a constant rate for straight line travel or charge direction, respectively, and a castering wheel provides stability and accommodates the direction of travel. Alternatively, a single wheel can provide both motive power and steering capability under control of a control unit responsive to the tracking unit and a pair of free wheeling wheels provide stability.

Claims

1. A self propelled automated refuse container comprising in combination:

a) refuse container having a hinged lid;

b) at least one driving wheel for transporting said container;

c) at least one steering wheel for steering the direction of travel of said container;

d) a tracking unit for controlling the direction of travel of said container;

e) a microprocessor for controlling operation of said container; and

f) a source of power for operating said driving wheel, said steering wheel, said tracking unit and said microprocessor.

2. The self propelled automated refuse container as set forth in claim 1, wherein said steering wheel includes an electric motor for turning said steering wheel to control the direction of travel of said container.

3. The self propelled automated refuse container as set forth in claim 2 wherein said steering wheel comprises said driving wheel and including an electric motor for rotating said steering wheel to provide motive power.

4. The self propelled automated refuse container as set forth in claim 3 wherein said steering wheel includes an electric motor for turning said steering wheel to control the direction of travel of said container.

5. The self propelled automated refuse container as set forth in claim 3, including a jack screw for raising and lowering said steering wheel on command from said microprocessor.

6. The self propelled automated refuse container as set forth in claim 1, including means for selectively raising said lid.

7. The self propelled automated refuse container as set forth in claim 1 wherein said at least one driving wheel comprises a pair of wheels and including a first electric motor for rotating one wheel of said pair of wheels and a second electric motor for rotating the other wheel of said pair of wheels to effect both travel of said container and to control the direction of travel of said container, said steering wheel being a castering wheel to accommodate a change in direction of travel of said container prompted by said pair of wheels.

8. The self propelled automated refuse container as set forth in claim 7, including a jack screw for selectively raising and lowering said castering wheel.

9. The self propelled automated refuse container as set forth in claim 1, including a parking station for storing said container, said source of power comprising a battery and said parking station including a further source of power for charging said battery.

10. A method for transporting a refuse container from a storage location to a location for discharge of the contents of the refuse container and return, said method comprising the steps of:

a) energizing at least a driving wheel to cause travel of the container;

b) controlling the direction of travel of the container with at least a steering wheel;

c) directing travel of the container along a predetermined track to and from the discharge location; and

d) terminating travel of the container upon return to the storage location.

11. The method as set forth in claim 10 wherein said step of energizing is carried out by a pair of driving wheels, each driving wheel including an electric motor selectively activated to provide motion for the container and to provide direction of travel of the container to carry out said step of controlling.

12. The method as set forth in claim 10 wherein said step of controlling is carried out by an electric motor turning a single steering wheel and wherein said step of energizing is carried out by a further electric motor rotating the single steering wheel.

13. The method as set forth in claim 12, including the step of raising the single steering wheel upon arrival of the container at the discharge location and the step of lowering the single steering wheel prior to return of the container to the storage location.

14. The method as set forth in claim 10, including the step of providing electric power from a battery to carry out said steps of energizing, controlling, directing and terminating.

15. The method as set forth in claim 14 including the step of charging the battery at the storage location.

16. A self propelled automated refuse container comprising in combination:

a) a refuse container including a hingedly attached lid for receiving and discharging refuse;

b) a pair of wheels mounted at the rear of said refuse container, each of said wheels including an independently activated electric motor for driving the respective wheel;

c) a castering wheel mounted at the front of the refuse container to accommodate forward and backward travel and change of direction of said refuse container;

d) a tracking unit for controlling the direction of travel of said refuse container from a storage location to a refuse discharge location and return; and

e) a microprocessor for controlling the travel of said refuse container.

17. The method as set forth in claim 16, including means for raising said castering wheel upon arrival at the discharge location and for lowering said castering wheel prior to return of said refuse container to the storage location.

18. The method as set forth in claim 16, including means for selectively raising and lowering said lid.

19. A self propelled automated refuse container comprising in combination:

a) a refuse container, including a hingedly attached lid for receiving and discharging refuse;

b) a pair of wheels mounted at the rear of said refuse container for rolling said refuse container;

c) a steering and driving wheel mounted at the front of the container including a first electric motor for driving said steering wheel to provide locomotion for said refuse container and a second electric motor for turning said steering wheel to control the direction of travel of said refuse container;

d) a tracking unit for controlling the direction of travel of said refuse container from a storage location to a refuse discharge location and return; and

e) a microprocessor for controlling the travel of said refuse container.

20. The method as set forth in claim 19, including means for raising and lowering said steering and driving wheel upon arrival at discharge location and for lowering said steering and driving wheel prior to return of said refuse container to the storage location.

21. The method as set forth in claim 19, including means for selectively raising and lowering said lid.
