Ultraviolet germicidal irradiation (UVGI) is a disinfection method that uses short-wavelength ultraviolet (ultraviolet C or UV-C) light to kill or inactivate microorganisms by destroying nucleic acids and disrupting their DNA, leaving them unable to perform vital cellular functions. UVGI is used in a variety of applications, such as food, air, and water purification, or treat biologically contaminated surfaces.

Recent studies have shown that UV short-wave radiation is capable of eliminating COVID-19, MERS, and SARS viruses at the hospital level, thus improving the cleanliness of the intensive care area, general medicine rooms and individual rooms.

THIS AUTONOMOUS CAR HAS THE MAIN GOAL OF DESINFECTING THE ROOMS OF A HOUSE.

The effectiveness of germicidal UV depends on the length of time a microorganism is exposed to UV, the intensity and wavelength of the UV radiation, the presence of particles that can protect the microorganisms from UV, and a microorganism's ability to withstand UV during its exposure. https://en.wikipedia.org/wiki/Ultraviolet_germicidal_irradiation

THE PARTICULAR GOALS OF THIS PROJECT ARE: 

  • 3D printing of the list of parts that will be used to assemble the Autonomous Robot;
  • Mounting the Chassis: "4WD Robot Car";
  • "Alexa Echo Dot" connection with the ESP32-WROOM-32 board, to transmit voice commands to the Autonomous Robot;
  • Calculation of Neural Networks with Python to be used on the Arduino UNO board, and to control the Autonomous Robot;
  • Use of a PID Controller to control the speed of the Autonomous Robot; and
  • Use of the Tesla coil to turn on an UV lamp.

SECTIONS: 

  1. COST EFFECTIVENESS
  2. PRINTING CUSTOM PARTS 
  3. 4WD ROBOT CAR 
  4. ECHO DOT & ESP32-WROOM-32 
  5. NEURAL NETWORKS 
  6. PID CONTROLLER 
  7. TESLA COIL & UV LAMP 
  8. TEST 
  9. CONCLUSION 
  10. REPOSITORIES ON GITHUB

    This project begins by justifying its economic viability, and we have asked ourselves several questions: Is it possible to manufacture and sell it? Who are the possible consumers? Where to sell it? Where to distribute it? Will this product be economically successful?

    As the introduction to the contest mentions, economically speaking these devices are not accessible to many people:
    "Versatile UV Wand for curing UV adhesive: UV Cure Adhesives are an incredibly powerful tool for fabrication and prototyping that cure within seconds of UV-A exposure. The technology is commonly used in at-scale production of medical devices, automotive, and in aerospace applications. Standard bench top UV cure stations cost more than a 1,000 USD. Traditional technologies for UV curing do not take advantage of LED light, as affordable UV LED technology has only matured in recent years."

    ADVANTAGES:

    • This project is an open source, cost effective, and energy efficient UV curing tool that can easily be fabricated in remote areas. Cheap, easily built manufacturing tool allow them to provide better aid in poverty.
    • The device is an autonomous robot, so we avoid exposing people to unwanted infections in areas that can be sanitized.
    • The autonomous robot is small dimensions and can therefore be used in homes without any problem.
    • This robot obeys voice commands, so we can adapt it for people with disabilities.

    PRICE:

    The price of the hardware components for this project is approximately $ 250 USD. This is a good design that can serve as a model to calculate the price of a larger device or with more lamps or with a reflector.

    In the international market, What is the price of these robots?

    • UVC hospital sterilizer movable UV sterilizer efficient surface sterilization. Price: $ 3,680 USD

I've solved the problem: to develop an autonomous robot car that can sanitize the rooms of an apartment or house using UV light and cheap hardware.
