Development Of Autonomous Lawn Mower From Locally Sourced Materials

ABSTRACT

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 pollutions 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 microcontroller

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 /own mower from locally sourced materials is

highly recommended because it is safer to use, environmental friendly, easy to operate, and fully automated.
