Pollution is a result of human activity, as evidenced by our daily lives. IC engines were employed in older models of lawn cutters, and as a result of their increased environmental effect, IC engine propelled cutters are more expensive. The cost of maintaining a traditional machine is higher. To overcome such drawbacks we want to build a new type of autonomous lawn cutter that works on solar energy and is also cost-effective to avoid these problems. The project's goal is to build a grass-cutting machine system that uses solar energy to power the grass-cutting machine. The "Solar Powered Grass Cutting Machine" is a solar-powered robotic vehicle that avoids obstructions and monitors soil moisture. The vehicle movement motors and the lawn cutter motor are both powered by a 12V battery. The battery is charged by a solar panel, eliminating the need for external charging. The grass cutter and vehicle motors are connected to a microcontroller, which regulates the operation of all the motors. It's also connected to an ultrasonic sensor that detects obstacles. If no barrier is identified and the moisture level is less than 50%, the microcontroller drives the vehicle motors forward. The ultrasonic sensor detects an obstruction, and the microcontroller shuts down the grass cutter motor to prevent any damage to the object/human/animal, and it also sounds an alarm. The microcontroller then rotates the vehicle till it is clear of the item, after which it moves the grass cutter ahead again. I.INTRODUCTION The goal is to avoid India's energy problem while also lowering human labour, operational costs, and maintenance costs. The use of a solar-powered grass cutter also helps to maintain the environment clean and healthy. It's used to chop a variety of grasses for a variety of purposes. The entire gadget is powered by solar energy stored in a battery. The ultrasonic sensor is used to detect obstacles protect humans, objects, and animals from harm and moisture in order to prevent internal parts of machine to get damage from excessive water. Since the dawn of time, the sun has been the primary source of energy for human lifestyles. Solar energy was quickly put to use for a variety of purposes, including drying clothes, curing agricultural produce, and storing meals, and several others. Even to this day, we get our energy from fuels like wood, petroleum, paraffin, hydroelectricity, and even our food, which comes from the sun directly. Solar energy is almost unlimited. The overall amount of energy we receive from the sun considerably outranks our need. Since the technological age, humans have relied on fuels, electricity, and wind power. We developed our novel idea sun powered grass cutting machine, in which we cut grass at agricultural products or on small plants in lawns and gardens. Many countries are investigating and evaluating solar and wind energy for human growth, thus we created our new concept sun powered grass cutting machine. The completely automated solar lawn cutter is a solar-powered grass-cutting robotic mower that uses ultrasonic sensors to avoid obstacles and is capable of automatic grass cutting without the need for human interaction. II. LITERATURE SURVEY Grass cutting machines are becoming increasingly popular these days. Pollution is a result of human activity, as evidenced by our daily lives. The goal of our project is to develop a solar-powered grass cutter that saves electricity and reduces labour. Some student journal papers are investigated. The important points and findings from those papers are outlined below. The work "SOLAR BASED GRASS CUTTER" was published in the "2nd International Conference on Latest Trends in Engineering, Science, and Management, New Delhi, 2017." This paper explains the design of a solar-powered automatic lawn mower that eliminates the disadvantages of traditional lawn mowers. The goal is to minimize India's energy crisis by decreasing overall labour, operational costs, and
