Intelligent Energy Harvester Solar System for Lawn Mower Application

Energy harvesters are a very fast Engineering field that comes with different combinations of technology that reduces human effort and gives maximum output. Hybrid means it can work both in sun and rain weather. Nowadays, lots of energy and human effort is being wasted on mowing the lawn in different parts of the world. The aim is to develop an all weather intelligent energy harvester lawn mower that will mow the lawn in all season, with no human effort, no pollution in terms of noise, air, and less energy consumption. More to these, the system has sensors to prevent or divert obstacles, making it operate independently. The concept of this work is to utilize renewable energy, reduce power conversion efficiency, and provide a good selfless and easy environment for grass cutting no matter the weather condition. In this work, a lawn mower is developed and a smart control system for the prevention of obstacles. The hybrid solar panel and graphene were developed to accommodate the output of weather conditions. The sun and rain droplet stays on them and is converted to electricity, it goes through a DC DC boost converter, passes through a stabilizer, and then to the battery for storing. The Direct current DC gear optimizes the directions. A motor driver was developed to drive the DC gears and a MOSFET driver for the blades and the rear tires. The rotating wheel rotates the direction, for each rear tire, is a motor. The solar panel was also used for charging the 12V battery, which is the engine brain of the system, it is controlled by 5V RPS. The RF receiver system receives and interprets commands for the remote control to the microcontroller. The solar panels supply energy to the battery and are controlled by the solar charge controller, which protects the battery from overcharging and maintains the batterys performance. The sensor senses an obstacle and sends it to the RF receiver for change in direction, and the second sensor is for motion detection, motor driver, and Bluetooth unit. The entire design is economical and fit with the objectives. Nwobodo Lois.
