Designing an Automatic Air Freshener Robot :: Robotics

The Automatic Air FreshenerOur project idea is to create an automatic appearance freshener robot. This robot will follow apath created by colored tape along a board to a holder with a piece of pH subject and liquids withvarying pH levels. After the paper is dipped into the liquid and the color changes, the robot willdetect what color it is and respond accordingly. If the odor is foul, it will choose to spray theair freshener. The solo thing it will be programmed to do is to detect the foul odor and tospray the air freshener, because that is its only purpose.Smell. One of our five senses. Its used everyday to athletic supporter us gain a better understanding ofour surroundings. But how does it work? Olfaction, or smell, is the detection of chemicals in oursurroundings. For humans, odors are processed in our olfactory epithelium. We pass on thousandsof genes that act as odor sensory receptors. Each of these genes act as a lock, with the odor moleculesacting as the key. When the c orrect odor molecule fits into the olfactory receptor neuron, a signalis sent to our brain, allowing it to determine whether the odor is pleasant or repulsive.In order to remove the foul odor, our robot will employ air fresheners. Many airfresheners use extracts from plants, fruits, and flowers. While the history of perfume dates backmillenia to the Ancient Egyptians, many modern-day armoatics are produced synthetically in alab. in that location are many different kinds on the market. One type of advanced air freshener workslike a charcoal or pollen filter. They filter out of the air all the foul smelling particles. Othertypes of air freshener stop absorb the odor molecules. Also, some disinfect by killing bacteriaand germs that sometimes cause the bad odors. However, most air fresheners use masking,introducing a stronger fragrance that humans find favorable, masking out the unpleasant smells.For our project, we will be using the type of air freshener that masks the smell.For ou r project, we were going to put together a robot that would be able to detect suchbad odors and to spray air freshener in the general area, thus masking the unwanted smell.Currently, there is no product on the market that does such a job. However, there is one productthat can detect bad smells and report the data to the user. It is a halitosis detector made by theJapanese company Tanita called Fresh Kiss (Tsunoda). It analyzes gas in ones back talk using a gas
