Abstract

A refuse collection vehicle includes a packer system with an auger screw, one or more refuse support panels, one or more sensing devices, and a refuse support panel actuator system. The refuse support panel(s) support refuse while characteristics of the refuse are sensed. The refuse support panel actuator system moves the refuse support panels such that refuse is released from the refuse support panels in to the packer system. A driver of the packer system rotates the auger screw such the refuse is packed into a storage compartment of the vehicle.

First claim

The invention claimed is:

1. A refuse collection vehicle defining forward and rearward directions of travel along a ground surface, a downward direction toward the ground surface, and an upward direction away from the ground surface, comprising:
a body comprising a storage compartment;
a packer system coupled to the body, the packer system comprising:
an auger screw operable to rotate to advance refuse into the storage compartment; and
a driver coupled to the auger screw and operable to rotate the auger screw such that refuse is packed into the storage compartment;

one or more refuse support panels coupled to the body, wherein the one or more refuse support panels are configurable to support refuse while characteristics of the refuse are sensed;
one or more sensors configured to capture sensor data of refuse while the refuse is on at least one of the one or more refuse support panels, the one or more sensors comprising a sensor located above the one or more refuse support panels relative to the upward direction such that refuse on the one or more refuse support panels is within a field of view of the sensor;
a refuse support panel actuator system configured to move at least one of the one or more refuse support panels such that refuse is released from the at least one of the one or more refuse support panels into the packer system; and
a control system configured to control the auger screw based at least in part on the sensor data.

2. The refuse collection vehicle of claim 1 , wherein the refuse support panel actuator system is configured to move at least one of the one or more refuse support panels to drop at least a portion of the refuse from the one or more refuse support panels onto the auger screw of the packer system.

3. The refuse collection vehicle of claim 1 , wherein at least one of the one or more refuse support panels comprises a flat surface, wherein the refuse support panel actuator system is configured to hold the flat surface substantially horizontally while characteristics of the refuse on the at least one of the one or more refuse support panels are sensed.

4. The refuse collection vehicle of claim 1 , wherein the refuse support panel actuator system is configured to move the at least one of the one or more refuse support panels to change an angle of inclination of the at least one of the one or more refuse support panels such that at least a portion of the refuse from the at least one of the one or more refuse support panels is released onto the auger screw of the packer system.

5. The refuse collection vehicle of claim 1 , wherein the one or more refuse support panels comprise a pair of doors, wherein the refuse support panel actuator system is configured to swing the doors away from one another to drop refuse from the one or more refuse support panels onto the auger screw of the packer system.

6. The refuse collection vehicle of claim 1 , wherein the refuse support panel actuator system comprises a linear actuator configured to move at least one of the one or more refuse support panels such that refuse is released from the at least one of the one or more refuse support panels onto the auger screw.

7. The refuse collection vehicle of claim 1 , wherein at least one of the one or more refuse support panels comprises a concave upper surface configured to hold refuse during sensing.

8. The refuse collection vehicle of claim 1 , wherein the refuse support panel actuator system is configured to rotate at least one of the one or more refuse support panels to release refuse from the at least one of the one or more refuse support panels onto the auger screw of the packer system.

9. The refuse collection vehicle of claim 1 , wherein the refuse support panel actuator system is configured to translate at least one of the one or more refuse support panels to release at least a portion of the refuse from the at least one of the one or more refuse support panels onto the auger screw of the packer system.

10. The refuse collection vehicle of claim 1 , wherein the at least one of the one or more refuse support panels comprises a conveyor belt, wherein at least one of the one or more sensors is configured to capture at least a portion of the sensor data of the refuse while the refuse is carried on the conveyor belt.

11. The refuse collection vehicle of claim 1 , wherein at least one of the one or more sensors comprises a camera comprising one or more image sensors.

12. The refuse collection vehicle of claim 1 , further comprising a lifting component configured to empty a container of refuse onto at least one of the one or more refuse support panels.

13. The refuse collection vehicle of claim 1 , further comprising a separator device configured to separate at least one item of refuse on the one or more refuse support panels from at least one other item of refuse on the one or more refuse support panels.

14. The refuse collection vehicle of claim 13 , wherein the separator device comprises a robotic arm operable to pick items from at least one of the one or more refuse support panels.

15. The refuse collection vehicle of claim 1 , further comprising a computing device configured to distinguish, based on sensor data captured by one or more imaging devices, at least one item of refuse on the at least one of the one or more refuse support panels from at least one other item of refuse on the at least one of the one or more refuse support panels.

16. The refuse collection vehicle of claim 1 , further comprising a computing device configured to detect, based on sensor data captured by the one or more sensors, contamination in the refuse on the one or more refuse support panels.

17. The refuse collection vehicle of claim 1 , wherein the control system comprises a computing device configured to control at least one of the one or more sensors, wherein the computing device is configured to detect, in response to operational sensor data indicating an operational state of one or more body components of the refuse collection vehicle, a triggering condition for capturing an image.

18. The refuse collection vehicle of claim 1 , wherein the control system comprises a computing device configured to control the refuse support panel actuator system, wherein the computing device is configured to detect, in response to the sensor data, a triggering condition for releasing refuse from at least one of the one or more refuse support panels into the packer system.

19. The refuse collection vehicle of claim 1 , wherein the control system comprises a computing device configured to:
control the refuse support panel actuator system; and
control the auger screw based at least in part on the control of the refuse support panel actuator system.

20. The refuse collection vehicle of claim 19 , wherein, to control the auger screw, the computing device is configured to:
implement, based on a determination that the refuse has been released from the at least one of the one or more support panels into the packer system, a first operation state of the auger screw; and
implement, based on a determination that the refuse has not been released from the at least one of the one or more support panels into the packer system, a second operation state of the auger screw, wherein the second operation state is different from the first operation state.

21. A method of collecting refuse, comprising:
placing refuse on a panel in a refuse collection vehicle;
capturing, using one or more sensors, sensor data associated with one or more characteris
