Self sanitizing storage of a delivery robot
A delivery robot includes a cargo bin to carry cargo for delivery, and a door coupled to the cargo bin. The door to the cargo bin has an open state to allow access to an interior of the cargo bin, and a closed state to seal the interior of the cargo bin from an exterior environment. The delivery robot also includes a disinfecting light source operable to generate a disinfecting radiation to disinfect the interior of the cargo bin. The disinfecting light source is allowed to be activated when the door is in the closed state, and is prevented from being activated when the door is in the open state.
1. A delivery robot comprising:
a cargo bin;
a door coupled to the cargo bin, wherein the door has an open state to allow access to an interior of the cargo bin, and a closed state to seal the interior of the cargo bin from an exterior environment; and
a disinfecting light source operable to generate a disinfecting radiation to disinfect the interior of the cargo bin, wherein the disinfecting light source is allowed to be activated when the door is in the closed state, and is prevented from being activated when the door is in the open state,
wherein the delivery robot is programmed to navigate a delivery route to a destination, and
wherein a controller of the delivery robot is configured to activate the disinfecting light source for a first duration of time after departing the destination.
2. The delivery robot of claim 1 , wherein the interior of the cargo bin includes a reflective surface to reflect the disinfecting radiation toward a portion of the interior of the cargo bin.
3. The delivery robot of claim 1 , wherein the interior of the cargo bin includes a transmissive surface to transmit the disinfecting radiation toward a portion of the interior of the cargo bin.
4. The delivery robot of claim 1 , wherein the door is arranged on a topside of the cargo bin, and the disinfecting light source is mounted on an inside surface of the door.
5. The delivery robot of claim 1 , wherein the disinfecting light source has a circular loop shape.
6. The delivery robot of claim 1 , wherein the disinfecting light source has a linear shape.
7. The delivery robot of claim 1 , wherein a controller of the delivery robot is configured to activate the disinfecting light source for a second duration of time before arriving at the destination.
8. The delivery robot of claim 7 , wherein the controller is configured to keep the disinfecting light source activated for a third duration of time once the delivery robot has arrived at the destination.
9. The delivery robot of claim 8 , wherein the third duration of time is less than the second duration of time.
10. The delivery robot of claim 7 , wherein the destination is a cargo pickup location, and the first duration of time is longer than the second duration of time.
11. The delivery robot of claim 7 , wherein the destination is a cargo drop-off location, and the first duration of time is shorter than the second duration of time.
12. The delivery robot of claim 1 , wherein the disinfecting light source includes an ultraviolet light-emitting diode (UV LED).
13. The delivery robot of claim 1 , wherein the disinfecting light source includes an ozone creating vacuum-ultraviolet light source that generates ozone.
14. The delivery robot of claim 13 , further comprising a fan operable to circulate the ozone in the cargo bin.
15. A computer-implemented method comprising:
initiating a delivery robot having a cargo bin to traverse a delivery route to a destination;
activating a disinfecting light source integrated with the delivery robot for a first duration of time to disinfect an interior of the cargo bin prior to arriving at the destination;
determining that the delivery robot has arrived at the destination;
in response to determining that the delivery robot has arrived at the destination, deactivating the disinfecting light source while the delivery robot is stopped at the destination;
determining that the delivery robot has departed the destination; and
in response to determining that the delivery robot has departed the destination, reactivating the disinfecting light source to disinfect the interior of the cargo bin for a second duration of time.
16. The computer-implemented method of claim 15 , wherein the destination is a cargo pickup location, and the second duration of time is shorter than the first duration of time.
17. The computer-implemented method of claim 15 , wherein the destination is a cargo drop-off location, and the second duration of time is longer than the first duration of time.
18. The computer-implemented method of claim 15 , further comprising displaying an indicator on an exterior of the delivery robot to indicate whether the disinfecting light source is activated.
