1. INTRODUCTION
Smart solar grass cutter robots have become very popular
today. Grass cutter robot is used for autonomous grass
trimming. In a time where technology with environmental
awareness, machines are looking for relief of their own
carbon footprints. So, we prepared a model of the automatic
grass cutting robot operates through solar energy, (non
renewable energy. This robot reduces environmental
pollution. In this robot, the powering a grass cutter by solar
energy rather than the fuel energy is mainly
environmentally. The gardenerusedhand scissorstocut and
maintain lawn regularly which also takes more time. It is
very difficult to maintain uniformity. But the unskilled
gardener can be easily operate the solar grass cutter.
2. LITERATURE SURVEY

5. L298N Motor driver
The L298N motor driver is a H-Bridge motor driver which
provides speed and direction controloftwoDC motorsatthe
same time. The driver module can drive DCmotorsthathave
voltages between 5 and 35V, with a max. current up to 3A.
We can control the speed of the DC motor by controlling the
supply voltage to the motor and it is done by using PWM
signal. The module has two terminal pin for the motor 1 and
2, and another terminal pin for the Ground pin, the VCC pin
which gives input or output 5V.

Block Diagram Description 1. Arduino uno Arduino is a gadget which is utilized for hardware ventures. Arduino comprises a programmable circuit board (microcontroller) and a bit of programming, or IDE (Integrated Development Environment) that keeps running in the PC. It used to compose and transfer computer code to the programming board. Board requires +5v for working legitimately. It gives 20mA current. Fig. Arduino UNO 2. Ultrasonic Sensor The ultrasonic sensor uses ultrasonic sound to measure the distance of an object. It furnishes non-contact remove recognition with high exactness and stability in readings from 2 cm to 400 cm. Its working isn't influenced by daylight. It comes with ultrasonic transmitter (trig) and receiver (echo) for measuring distance. Fig. Ultrasonic sensor 3. DC Gear Motors (100 rpm) There are 4 Gear DC 12volt motorsareused formovementof the wheel. The speed of the gear motor is 100 rpm on load. These Motors are driven by the motor driver L298nmodule. Motors require more current for work properly so this IC is used. It increases current up to 480mA. Fig. DC Gear motor 4. 775 DC Motor (10000 rpm) 775 DC motor is used for cutting operation of the grass. It is operates on 12 volt and 2.68 Amps on DC supply. This motor has more Speed than the other DC gear motors. TheseMotor has speed of about 10000 rpm. Metallic thread is attached to the motor for cutting the grass. And it controlled bytherelay which is trigger by the help of arduino. Fig. 775 DC motor 5. L298N Motor driver The L298N motor driver is a H-Bridge motor driver which provides speed and direction controloftwoDC motorsatthe same time. The driver module can drive DCmotorsthathave voltages between 5 and 35V, with a max. current up to 3A. We can control the speed of the DC motor by controlling the supply voltage to the motor and it is done by using PWM signal. The module has two terminal pin for the motor 1 and 2, and another terminal pin for the Ground pin, the VCC pin which gives input or output 5V. Fig. L298n Driver module 6. Batteries Solar panel produces electricity in the day light only. Itisnot store energy. So, it is require to store the electricity produced. So we use batteries (6 volteach)tostoreelectrical energy generated by the solar panel. It is also used for the powering operation system. The 6 volt batteries are connected in series for 12 volt DC supply. And it charged on the charging dock through charging socket and charging dock is connected with solar panel and charging controller. Fig. Battery 7.
