5. The decontamination system of claim 1 , wherein the decontamination apparatus comprises a plurality of UVC sensors that provide data on the UVC light intensity experienced where each UVC sensor is placed on the surface.
6. The decontamination system of claim 1 , wherein the at least one UVC sensor is configured to transmit a signal providing the location of the at least one UVC sensor to the decontamination apparatus.
7. The decontamination system of claim 1 , wherein the at least one UVC sensor is configured to transmit a signal that directs the decontamination apparatus to move to the location of the UVC sensor when the UVC sensor detects that the UVC sensor has been exposed to less than a defined level of UVC light.
8. The decontamination system of claim 1 , wherein the decontamination apparatus is equipped with a proximity sensor to detect when a portion of the decontamination apparatus is approaching a foreign object.
9. The decontamination system of claim 1 , wherein the UVC sensors are configured to transmit a signal that alerts when UVC light is detected at a time when there should be no irradiation in progress.
10. The decontamination system of claim 1 , wherein the plurality of bulbs are adjustably coupled to the base to be independently-positionable relative to each other.
11. The decontamination system of claim 1 , wherein the wherein the plurality of bulbs are each supported by an adjustable arm that is pivotally coupled to the motorized base.
12. A decontamination system comprising:
at least one UVC sensor configured to be positioned on a surface to be decontaminated, wherein the at least one UVC sensor is configured to transmit a signal to request a decontamination apparatus move to the location of the UVC sensor;
the decontamination apparatus comprising
a motorized base comprising a transport system that is operable to move the decontamination apparatus;
a plurality of UVC bulbs that emit UVC light supported by the motorized base; and
a controller that (i) receives a signal indicative of the UVC light experienced by the at least one UVC sensor and (ii) controls operation of the transport system to move the motorized base along a route based on the received signal indicative of the UVC light experienced by the at least one UVC sensor, wherein the controller controls the decontamination process by:
receiving input indicating that the motorized base is at a first location;
receiving data collected by a first UVC sensor at the first location that detects the UVC dose received by the first UVC sensor; and
directing the decontamination apparatus at the first location to a second location after the first UVC sensor indicates a defined UVC dose has been received by the first UVC sensor.
13. The decontamination system of claim 12 , wherein the controller is further configured to control operation of the decontamination apparatus to cause the motorized base to travel from the first location to the second location during the decontamination process.
14. The decontamination system of claim 13 , wherein the controller is further configured to control the decontamination process by:
receiving input indicating that the motorized base is at the second location;
receiving data collected by a second UVC sensor at the second location that detects the UVC dose received by the second UVC sensor; and
directing the decontamination apparatus at the second location to a third location after the second UVC sensor indicates a defined UVC dose has been received by the second UVC sensor.
15. The decontamination system of claim 13 , wherein the controller is further configured to control operation of the decontamination apparatus to cause the motorized base to travel from the second location to the first location following a decontamination process.
16. A method of operating a decontamination apparatus comprising a motorized base that supports a plurality of UVC bulbs and a controller, the method comprising:
receiving an input signal indicating that the motorized base is positioned at a first location;
receiving a signal from a first UVC sensor that detects a UVC dose received by the first UVC sensor; and
directing the motorized base to move to a second location when the first UVC sensor has received a defined UVC dose.
17. The method of claim 16 further comprising, in response to receiving an instruction to conduct a decontamination process:
causing the plurality of UVC bulbs to be energized; and
controlling operation of the motorized base to cause the motorized base to navigate from the first location to the second location.
18. The method of claim 17 , wherein the plurality of UVC bulbs are energized after a predetermined period of time has elapsed following receipt of the instruction to conduct the decontamination process, wherein the predetermined period of time is suitably long to allow an operator who issued the instruction to conduct the decontamination process to exit a room in which the decontamination apparatus is located.
19. A decontamination system comprising:
one or more UVC sensors configured to be positioned on a surface to be decontaminated, wherein the one or more UVC sensors are configured to transmit a signal to request a decontamination apparatus move to the location of the UVC sensor;
the decontamination apparatus comprising
a motorized base comprising a transport system that is operable to move the decontamination apparatus;
a plurality of UVC bulbs that emit UVC light supported by the motorized base; and
a controller that (i) receives a signal indicative of the UVC light experienced by the one or more UVC sensors; (ii) controls operation of the transport system to move the motorized base along a route based on the received signal indicative of the UVC light experienced by the one or more UVC sensors; and (iii) deactivates the UVC bulbs in response to a signal that all of the one or more UVC sensors have received a defined UVC dose.
