The Automatic Air Freshener
Our project idea is to create an automatic air freshener robot. This robot will follow a path created by colored tape along a board to a holder with a piece of pH paper and liquids with varying pH levels. After the paper is dipped into the liquid and the color changes, the robot will detect what color it is and respond accordingly. If the odor is “foul”, it will choose to spray the air freshener. The only thing it will be programmed to do is to detect the “foul odor” and to spray the air freshener, because that is its only purpose.
Smell. One of our five senses. It's used everyday to help us gain a better understanding of our surroundings. But how does it work? Olfaction, or smell, is the detection of chemicals

The exterior would be sleek and pleasing to look at, something we could not accomplish using Lego pieces. For our automatic air freshener robot, aside from Lego parts, we used a couple of non-
Lego pieces. First of all, because our robot is made to freshen the air, it needed a can of air freshener. For our project we chose to use a short can so the design of the robot would easier to build. Next, because we could not obtain any pH sensors, we will be using pH paper in place of it. In order to detect what the “unpleasant” scent is, we will use a light sensor and program the robot to correspond each color to a certain substance. Next, we needed to use Petrie dishes or cups to store the liquids of various pH levels. Also, because this robot will be fully autonomous, we need colored tape for the robot to follow. In our robot we included 5 motors, 2 light sensors,
2 RCXs, worm gears to improve the strength of our robot, many tooth gears, racks, belts, and belt pulleys. This is a list of all our materials:
Lego parts:
7 Motors
2 Light Sensors
2 RCXs
8 Worm Gears
9 24-Tooth gears
6 8-Tooth gears
416-Tooth Gears
8 Racks
2 Belt
4 Belt

This was not our robots problem, it was a problem with the obstacle course we made. Aside from the treads and the board there were no other major problems. All the other minor issues were resolved very quickly.
Now that our robot is complete, we can begin planning the next phase of our product. The prototype design was made and configured according to Lego Mindstorm pieces. If given the proper materials, we could create a new design, a design that would be attractive to the average consumer. After building the new product, we would conduct extensive testing on it to make sure nothing goes wrong, for example, exploding air freshener containers or a never ending stream of air freshener. The design would not be as bulky as our current prototype, because no one would want to buy something bigger than their dog for a simple task such as freshening their air.
Because we recognize that something like this would happen, we’ve decided to make the product smaller. This product will still be used in and advertised to the average household. Overall, this whole project was a very enlightening experience that has allowed me to see what it’s like
Natural body odor attributes from secretions of sweat, urine, saliva, and genital excretion. Personality traits such as neuroticism, extraversion, and dominance elicit associations with ones body odor. The olfactory system has the ability to learn quickly. With that being said, repeated emotional experiences may create a scent in response to the under or overproduction of secretions making that emotion or trait detectable to others. For example neuroticism is defined as the tendency to experience anxiety, nervousness, fear and easily upset. Emotions that stimulate and sustain the sweat glands customizing ones own personal neurotic aroma.
Briefly describe the path of information from the targeted sensory organs (eye, ear, skin, and nose) to the brain.
Olfactory codes are very difficult to study and motor codes are not studied at all. These codes seem to be transitory and the info driven is encoded in the visual way or a linguistic way…
There's nothing worse than when someone goes to the toilet and leaves their utter stench of last nights meal behind them. Then, it always happens, they think they can make it all better by spraying some air freshener. Instead of making things better, they get worse. The air condition goes from unbearable to lethal. When the stench particles combine with the air freshener, it makes a deadly mask that seems to forever hang. Even napalm gas is better than this.
Although there are various features within the operant chamber, the only components that are actively used in these experiments are the bar and food hopper. In order to conduct the 3 main experiments for this research, we must first conduct 2 precursor exercises to prepare the subject. The first precursor exercise is to magazine train the subjects to associate the sound of the magazine with the presentation of food. After launching the Sniffy Pro Version 3.0 program, we can observe the subject in the operant chamber. First, we open the Operant Associations mind window and the Cumulative Record to keep track of our data. We can then begin to train him by delivering a food pellet whenever he approaches the food hopper. We continue this procedure until the subject fully develops an association between the sound of the food hopper and the presentation of the food. The Operant Associations window displays the strength of the association at any particular time. Once the subject has completed developing the association, the sound of the food hopper can be used as a reinforcer to shape his
Scent is part of the five senses that are developed when an infant is still in the mother’s womb. It is processed by a part of the brain that correlates with memory, so at a young age an infant could differentiate who their mother is by scent. Odor is a sign and olfactory condition (Waskul & Vannini, 2008). As someone gets older they begin to develop scents they like and dislike. There are also scents that people find attractive and unattractive. When meeting another individual for the first time a human’s first instinct is to smell them without realizing it. For instance, have you ever sat by someone or hugged someone who smelled good or bad? If so, many people tend to associate the scent with attractiveness or unattractiveness depending on the level of smell. There have been many studies indicating that there is a strong correlation between odor and attractiveness. Although the scent is a universal and an undetectable smell it can influence the level of perceived attractiveness of another person.
In this time of age, things have been consuming a lot of electricity compared to the old electrical appliances. People have been innovating different types of electrical appliances to reduce the amount of electricity used by the household such as air conditioner, refrigerator, television, and other appliances. One way of saving electricity which have been introduced in the new era is the Bio Robot Refrigerator introduced by a student from Russia, Yuriy Dmitriev, which is one of the 25 finalists in the Electrolux Design Lab competition. The competition is to challenge the entrants to redesign the modern appliances for the future.
Pollution prevention includes any method which reduces the amount of toxic substances used and which minimizes waste streams. The laboratory uses solvents, reagents, and standards that are frequently toxic. Some of these substances may escape into the atmosphere by evaporation, and some are carried out of the laboratory by the fume hood system. Minimizing the quantity of the substances used and minimizing their exposure to the atmosphere are important in pollution prevention. Containers of samples, standards, solvents, and reagents shall be kept closed if possible.
Perception, at most times, is a credible way to assess the world around us. Without perception, we would not know what to do with all the incoming information from our environment. Perception is constructed of our senses and the unconscious interpretations of those sensations. Our senses bring in information from our environment, and our brain interprets what those sensations mean. The five most commonly accepted senses -- taste, smell, hearing, sight, and touch -- all help create the world around us as we know it.
Contamination of Water and Air. Urbanization enhances the proliferation of industries, automobiles, and agricultural practices. Most toxic air contaminants are produced as we endeavor to fuel our homes, automobiles, factories, energy production facilities, and might also be discovered in indoor cleansing mixtures, and construction supplies. Furthermore pollutants found in gasoline, dry cleaning services, and paint thinners and strippers; som...
Sensation refers to the process of sensing what is around us in our environment by using our five senses, which are touching, smell, taste, sound and sight. Sensation occurs when one or more of the various sense organs received a stimulus. By receiving the stimulus, it will cause a mental or physical response. It starts in the sensory receptor, which are specialized cells that convert the stimulus to an electric impulse which makes it ready for the brain to use this information and this is the passive process. After this process, the perception comes into play of the active process. Perception is the process that selects the information, organize it and interpret that information.
First, one must have the five senses; taste, smell, hear, see, and feel. Yes, these are physical aspects, however, these senses are what any human needs to be, human. For example, the human body needs to be able to taste. It must ingest food, and the food must appeal to a decent taste. A human must also be able to smell, so one may smell a poisonous gas, delicious food, or any other stench that may linger in the air. To be able to hear, enables the human to hear danger or a noise that appeals to them. When seeing, danger is also noted as well as the care of others. When one feels, the object that is being felt may make the person feel comfortable. Not only the sense of touching, but feelings.
The five senses of sight, hearing, touch, taste and smell are all sensations throughout the human body. Sensation is the involvement of sensory receptors as well as the central nervous system in order to allow us to experience outside stimuli. The system that allows us to experience sensation is the sensory system.
A piece of carpeting collected at the scene of a suspected arson is sent to the lab in an evidence collection can. Explain the methods that can be used to extract any volatile components that may be trapped in the carpet fibers?
For example, if u paint a wall, the house will most likely smell making it hard to breathe.
