Robotic lawnmower and water sprinkler with Internet of Things connectivity and solar power

Abstract

Keeping greenery healthy is a labor-intensive activity in the world of smart applications. The traditional grass cutters which use fuels may have destructive effects on the environment. This Internet of Things (IoT)-driven robotic lawn mower (100) focuses on reducing environmental concerns, and sustainability by using solar power and reducing human efforts for lawn maintenance. The earlier robotic grass cutters were used only for grass cutting in required patterns whereas this Robotic device is used for multitasking i.e., grass cutting and water sprinkling when needed. Using sensor technologies, Internet of Things powered grass cutters and water sprinklers can navigate, mow the lawn and sprinkle water when necessary. It can be used day or night because solar energy is utilized for charging it. The IoT-driven robotic grass cutter (100) has demonstrated its capabilities in navigating, lawn mowing, and water sprinkling. This robotic technology is affordable, environmentally friendly, and sustainable because it operates on solar power. This research demonstrates how the IoT may be used to develop intelligent, automated solutions for routine operations. IoT continues to advance, its contribution in this research can create sustainable and efficient lawn maintenance.
