Abstract:
The system development is being motivated by the need to reduce on the cost incurred on
buying fuel for lawn mowers. This has affected lawn mower users due to the increasing
fuel prices almost every year. The system though has more added advantages like
reducing pollution and automation.
The system comprises of different units, the solar powering unit, the grass cutting unit
and the movement unit which includes the obstacle avoidance unit.
The system is powered by solar energy which is generated by a solar panel that moves
with the system on top, the generated energy is then stored by two solar batteries through
a solar charge controller. The batteries then supply power to the movement motors and to
the grass cutting motors plus other electronic components.
The system operates in such a way that a user inputs the dimensions of the area to be cut
in terms of length and width through a keypad and an LCD, then the system starts to
move the input dimensions while cutting the grass and avoiding any obstacle found along
its route. When the input area is covered, the system will automatically stop.
