#MAP128 Android Controlled Lawn Mower_Grass Cutter.

Android Controlled Lawn Mower_Grass Cutter.

 Android Controlled Lawn Mower

In this project, a newly designed lawn mower was fabricated which powered through a rechargeable battery. Besides that, the grass cutting machine was fabricated at low cost by taking consideration on important aspects such as lightweight, durable, and environmental friendly. A lawn mower is a machine that uses cutting blades or strings which is used to cut the grass in gardens or yards at an even length. The working principle of the lawn mower is to provide a high speed rotation to the blades, which aids in cutting the grass through generated kinetic energy. The main concentration of this study is to design and fabricate a lawn mower which is cost effective, feasible and easy operation. With the help of this portable lawn mower, consumers can easily maintain and beautify their yards and gardens without any hassle.
