Abstract
Each weekend, about 54 million Americans mow their lawns, using 800 million gallons of gas per year and producing tons of air pollutants. Garden equipment engines, which have had unregulated emissions until the late 1990's, emit high levels of carbon monoxide, volatile organic compounds and nitrogen oxides, producing up to 5% of the USA’s air pollution and a good deal more in metropolitan areas. According to the U.S. Environmental Protection Agency (EPA), a new gas-powered lawn mower produces volatile organic compounds and nitrogen oxides emissions air pollution in in in one hour of operation as 11 new cars each being driven for one hour. The solar powered lawn mower is aa fully autonomous robot with capabilities to cut the grass independently. The robot uses 12v batteries to power itself and all the sensors. The motors to help move the robot and the grass cutter are controlled by and Arduino microcontroller that controls the movement based on incoming data from the ultrasonic sensors used for object detection and the humidity sensors to check for the non-grassy areas. The 12-volt battery is continuous charged by a solar panel housed on the top of the robot that also acts as a secure panel for weatherproofing the sensors underneath. The robot is compact and very cheap in comparison to any product in the market. The most common solar powered robot called the lanmow costs an upwards of $2000 and needs a technical installation. The solution presented here has a simple self-serve placement right out of the box. There is no technical installation required, no setup required and it is substantially cheaper than any current market solution while being environmentally friendly.
