Development of Autonomous Lawn Mower From Locally Sourced Materials

A lawnmower is a machine that uses a revolving blade or blades to cut a lawn grass. Many designs have been made, each suited to a particular purpose. Manual grass cutter has environmental issues regarding pollution's and also require the need of man power to operate and has a great maintenance to its engine. This robot is design to be environment friendly and operated by a rechargeable battery and can be describe as an intelligent robot because the micro-controller receives information from several sensors (PIR, Humidity and Bumper switches) connected to it in avoiding obstacle to ensure a neat pattern of cut and use the information to actuate the left and right motors driving the wheels and the center motor driving blade and at the same time it obeys all parameters of work and its program database. The result obtained from the test and analysis carried out shows that our development of the autonomous lawn mower from locally sourced materials is highly recommended because it is safer to use, environmental friendly, easy to operate, and fully automated.
