Designing an Automatic Air Freshener Robot :: Robotics

The Automatic Air FreshenerOur project idea is to farm an automatic place freshener robot. This robot exit follow a caterpillar track created by colored tape along a board to a holder with a piece of pH paper and liquids withvarying pH levels. After the paper is dipped into the liquid and the color changes, the robot will strike what color it is and respond accordingly. If the odor is foul, it will hire to spray the broadcast freshener. The only thing it will be programmed to do is to name the foul odor and tospray the air freshener, because that is its only purpose.Smell. nonpareil of our five senses. Its used everyday to help 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 have thousandsof genes that act as odor receptors. Each of these genes act as a lock, with the odor molecules acting as the key. When the correct od or 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 sustainmillenia to the Ancient Egyptians, many modern-day armoatics are produced synthetically in alab. There are many different kinds on the food market. One geek of advanced air freshener workslike a charcoal or pollen filter. They filter expose of the air all the foul smelling particles. otherwisetypes of air freshener can 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 our pro ject, we were sacking to put together a robot that would be able to detect suchbad odors and to spray air freshener in the general area, frankincense 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 let loose using a gas
