Within the last ten years the amount of cigarette smokers has dropped drastically, yet the surge of recreational cannabis use given the new laws have skyrocketed. This draws to concern the fact that more people are contaminating the air within their own areas even more than ever. This is where our Robotic Air Purifier comes in, our robotic air purifier will decontaminate any area using a grouping of sensors to detect polluted air and filter that air. Using a 7-stage filtration system, and a myriad of distance and pollution reading sensors the robot will move seamlessly throughout the area cleaning the air as it moves around the room. This product is especially designed for medium sized rooms, and large open areas. According to the Environmental Protection Agency, indoor air can be 2-5 times more polluted than the outdoors. This air pollution can trigger heart attacks and strokes. One out of every three Americans with heart or blood vessel disease are at a higher risk from bad indoor air quality. What’s more, humans shed their epidermis at the rate of 0.001 – 0.003 ounces of skin flake every hour. Our objective for this project is to design a robot that keeps the air clean through filtration. We designed this robot to be affordable and have at least 6-hour battery life. We are using four dc motors that will be controlled through a 4-dc motor H-Bridge shield that will be attached to an Arduino Uno R3. The various sensors that we are using are: MQ-2 Gas sensor, Air Quality Sensor, Dust Sensor, and an ultrasonic sensor. The ultrasonic sensor will help the robot avoid tall obstacles like walls.
