DESIGN AND MANUFACTURING OF SMART SOLAR GRASS CUTTER AND PESTICIDE SPRAY MACHINE

Abstract

Nowadays grass cutter machines are becoming very popular today. Pollution is manmade, which we can be seen in our daily life. In old model of grass cutter IC engine was used and hence because of its environmental impact pollution level rises IC engine driven cutter is more costly. Maintenance of such conventional machine is more. There are many types of pesticides sprayer are available in India. But mostly used sprayer is backpack type sprayer which is used by farmers because it is cheaper, easy to use and main thing about it is less costly, but it requires lot of time. Also, the farmer which is spraying pesticides is affected by it as it is harmful to human health and human also affect by the lumbar pain due to weight of equipment. To avoid these drawbacks, we plan to build new type of grass cutter which runs on solar energy and this model spray pesticides. The aim of our project is to make the grass cutter which operates on solar energy hence save the electricity and reduces manpower. In our project we use microcontroller for controlling various operation of grass cutter. Also, the grass cutter has obstacle sensor for obstacle detection. Grass cutter operates automatically hence it does not require skill person to operate. The main aim of our project is to design and develop solar grass cutter with pesticide spray machine. The 3 D model is drawn. All the parts are manufactured and then assembled together and then the testing of model is carried out.
