3. Abstract The basic project idea is to develop a grass-cutting robot controlled with help of the android application. Here the Bluetooth module is used to connect AVR Microcontroller with the phone and user is provided with a Android application to control this device. Previously the grass cutter machines are operated by fuel which is costly. Here the solar panel is utilised to charge the battery so that it doesn’t\ have to be charged externally .The sun-based energy source is more straightforward to utilize, more profitable contrasted with other energy and it is not difficult to work. By the use of solar panels, we can use sunlight to generate electricity free of cost. The solar panel is used to charge the battery for grass cutting purposes. The movement of the machine is totally controlled by using the Android app. The controlling device of the system is AVR Microcontroller. Bluetooth module and DC motors are interfaced to the Atmega 16 Microcontroller. The data received from the android phone application by the Bluetooth module is given as an input to the Atmega 16 Microcontroller and the controller acts accordingly on the DC motor of the solar grass cutter. And also here at the input, we have connected an ultrasonic sensor for obstacle detection whenever the obstacle is detected the Microcontroller sends the command to stop the machine.

4. Literature Review  Sultana et al. have represented A Review on Smart IoT based Gesture Controlled Grass Cutting Vehicle this paper focuses on how to control the machine using hand gesture.in this paper, they have used Arduino as well as raspberry pi controller and which increases the cost of the machine. Also, the system is a little complicated to understand. In this, they have used a battery to drive the motor which is connected to the solar panel. The limitations in it are that the project became costly and the system is complicated . Manimegalai et al. have represented Automatic Solar Powered Grass Cutter Incorporated with Alphabet Printing and Pesticide Sprayer in this paper they have used the alphabetic printing and pestical sprayer and also the solar panel for battery charging purpose with this cutter the alphabet printing is done on grass but its drawback is that we can give only alphabetical shape to grass we are not able to cover the whole lawn. Habib et al. have represented PID controller based automatic solar powerdriven grass cutting machine in this they have used PID controllers for controlling purpose but the drawback of this project is it will not stop the moving of blades when sudden obstacle will detected which can harm the animals or humans.

5. Introduction Robotization is beneficial at many stages of human life. The attractiveness of any hotel, residence, park, meeting hall, etc. is enhanced by the finely shaped trimmed grass. As a result, maintaining the status of any house or hotel requires consistent lawn trimming. Manual grass cutting is feasible with humans, but it generally takes a lot of their time and energy. Furthermore, manual grass mowing is inefficient and frequently results in non-uniform grass structure. To prevent all of these problems, it is preferable to utilize an automatic grass-cutting robot that can be controlled via a Smartphone. And also nowadays the rate of the fuel is increased and using grass cutter which uses fuel will be costly. So to reduce the cost of fuel solar panels are used. Now a day’s pollution is a major issue for whole world. Pollution is manmade and can be seen in own homes. In case gas powered lawn movers due to the emission of the gases it is responsible for pollution. Also the cost of the fuel is increasing. Hence it is not efficient. So the solar powered lawn cutters are introduced. Solar powered lawn mower can be described as the application of solar energy to power an electric motor which in turn rotates a blade which does the moving of a lawn. Dept. of ME, ACOE 11/17/2022

6. Objective of the project work  The objectives of the proposed work is to the design and construct the automated grass cutting robotic vehicle powered by solar energy which avoids obstacles without the need of human interaction. Dept. of ME, ACOE 11/17/2022

11. Experimental procedure This Project is designed using Atmega 16 Microcontroller as a brain of Grass cutting Robot. Ultrasonic sensor is interfaced with this Microcontroller unit. User is provided with a Android Application, using It user can control this robot within Bluetooth Range. User can control this robot by moving Forwa . rd, Backward, Left and Right Directin. L293D Motor Driver is used to drive the DC Geared Motor of 60 RPM. This motor are used to drive the Robotic Vehicle. 1000 RPM DC Geared Motor is used to drive the Cutting Blade to cut the grass.. LCD Module is used to display the Robot Movement status. LCD Module is interfaced with system to display the Robot Moving Status. Ultrasonic sensor is interface with system, to avoid any obstacle and crashing. If any obstacle found in its way, than robot stops automatically . Bluetooth Module is connected to the Serial Port of Microcontroller. LCD Module is connected to Port B of Microcontroller and Motor Output is given from Port A of Microcontroller. MIT App inventor is used to design the Android Application, using it user can control the hardware with in Bluetooth RF Range.
