Abstract

The cost implications and the stress involved in keeping our public and private residence clean at all times is becoming too high that even the rich, government and non-governmental organization finds it difficult to achieve. As a result of these, our environments are becoming largely un kept, this therefor encourages dangerous reptiles to co habit with man because of the bushy nature. Again, the availability and the reliability of the existing Lawn mower is not guaranteed due to the high cost of maintenance, inadequate skilled man power, and lack of spare parts for repairs. This work is therefore aimed at designing and developing a Lawn mower that is capable of carrying out clearing task, avoid obstacles during operations and powered by sunlight. An easy to operate lawn mower, low maintenance cost with little or near zero man machine interface was conceived, designed and developed. For the purpose of this work, materials were sought locally in line with the requirements of the task of clearing a fairly over grown grasses. Design calculations were carried out to aid material selections in line with engineering best practices. Finally, an autonomous lawn mower capable of cutting grasses using energy from the sun was designed, developed and tested. Our result showed that this machine so developed, cuts grasses effectively and efficiently with ease, sense and avoid obstacles close to it during operations and operate with little or no human supervision. It is therefore our view for government to scale up the manufacture of this machine so that our environment will be clean again, thus avoiding the huge effects of untidy, unclean and disease infested surrounding that will negatively affect our economic and health status as a nation.
