The Design, Development, and Testing of a Robotic Duct Sterilization System

Significance

Mold and bacterial growth in HVAC systems have negatively impacted the health of millions worldwide, and leaking ductwork increases costs of heating and cooling. The design and development of a robotic sterilization system irradiates and kills mold and bacteria in air conditioning ducts while at the same time remotely monitoring environmental conditions. This robot is significant in two specific areas: health and the economy. A portable, multitasking robotic system designed to monitor and disinfect ductwork could help keep people healthy while at the same time keep energy cost down. Disinfecting ductwork could prevent mold-related illnesses such as
Sick Building Syndrome.


Engineering Goals

Goal #1: The robot will follow a line
Goal #2: The robot will hold a UV light
Goal #3: The robot will turn off UV light by a light activated trigger
Goal #4: The robot will monitor humidity
Goal #5: The robot will monitor temperature
Goal #6: The robot will send data to second robot through 912 mHz transceiver.

Engineering Conclusion
Engineering Goal #1 was met, the robot was able to follow a line. Goal #2 was met, the robot was able to hold a UV light. Goal #3 was met, the robot was able to turn off the UV light by a light activated trigger. Goal #4 was met, the robot was able to monitor temperature. Goal #5 was met, the robot was able to monitor humidity. Goal #6 was met, the robot was able to send information to a second robot through 912 MHz transceiver.


Microbiology

The researchers also developed a hypothesis for testing the UV bulb on E.coli: The plates inoculated with E.coli irradiated with UV-C for 8 minutes will have less colonies when compared to plates inoculated for 0, 1, 2, 4, and 6 minutes of UV-C radiation.

Microbiology Conclusion
The data supported the hypothesis and the hypothesis was accepted. Plates irradiated for 8 minutes did have less E.coli colonies than the plates irradiated for 0,1,2,4, and 6 minutes.
