Project Summary

A lawn mower is a machine which is used for cutting grass or lawns, mostly healthy grass which needs to cut neatly like in a public park or a private garden. The purpose of this proposed project is to design a programmable automatic pattern design grass cutting robot that can be operated wirelessly using an Android Smartphone via Bluetooth from a safe distance which is capable of cutting the grass in indeed required shapes; the cutting blade can also be adjusted to maintain the different length of the grass. The main focus was to design a prototype that can work with a little or no user Physical interaction. The system can be moved to the location in the lawn remotely where the user wants to cut grass in desired patterns. The user can touch the desired pattern button, and the system will start cutting grass in the corresponding pattern such as a circle, spiral, rectangle and any other special pattern that the user wants. The system uses 12v batteries to power and uses Raspberry pie microcontroller as the primary tool. Ultrasonic obstacle detectors are used to detect obstacles if any obstacle is found in front of the robot while traveling; it avoids the obstacle by taking a right or left turns automatically appropriately thereby avoiding the collision.  In addition, the project aims at fabricating a lawn mower which makes the grass cutter motor run through solar energy.

Project Objectives

The Grasscutter will move to the desired location with an Android application and Cut the grass into different patterns like circle, rectangle, spiral and many others and there is no need of a manual operation because the system is fully automatic control with the technique of Internet of things.

1. It is much complicated, time-consuming and also need labor to cut a grass manually, so we aim to construct an automatic grass cutter which provides effortless grass cutting through mobile application while remaining at one place.
2. It is incredibly complex and confusing to cut grass manually in specific shapes or patterns in specialized areas such as football ground, cricket grounds, etc., so our primary objective to make grass cutter much faster and capable that it can cut the grass in desired patterns automatically with a single command.
3. As the energy resources are decreasing at an alarming rate, it is not much efficient to operate grass cutter only on the battery, so we will implement an energy saving system to charge the batteries through solar energy. 

Project Implementation Method

In this project, we will propose and experimentally demonstrate a design to construct an automation grass cutter robot through mobile. This work will be accomplished with the proper arrangements of the microcontroller Raspberry pie, dc motors, motor shield, cutter, mobile application, Bluetooth module, and ultrasonic sensors. First of all, connect the blade, Solar panel and DC Motors with Microcontroller on the grass cutter. A special Android application will be developed for the pattern design cutter which can contain an arrow touch button for movement of the robot from one place to the desired location and particular buttons for corresponding patterns. The user can simply connect the mobile application with the grass cutter through Bluetooth or wifi module. Where the user wants to move the grass cutter, he/she can press the button from an application, and this command will send to the Raspberry pie, and it will compare this command with the predefined values. If the user presses the forward arrow button, the microcontroller will understand this command and send a signal to the motor module to start the forward motors to move in forwarding direction.  This method will also work the same for moving backward, left or right turn. The application contains the pattern button, when the user wants to cut the grass in specific patter, simply presses the button on the application, and this signal is sent to the raspberry pie for an understanding of pattern, and it will send the command to the motor module to cut the grass in the corresponding pattern.

Benefits of the Project

This grass cutter is much efficient and sustainable for the environment and much easy to operate. As compared to traditional grass cutter, all have a lack of efficiency and smartness, because it can be operated manually. It was much time-consuming and costly because the operator can move the grass cutter to the desired location with the hand and then cut the grass. If the operator wants to cut grass in a specific pattern, it is much difficult for him to draw, as they lack performance and not have the ability to design a pattern as they desired to draw. Manual grass cutters are costly and consume more energy, moreover there we need more than one person to cut the grass. In the start, conventional grass cutters had connected by a long electrical wire, and the operator must be careful about the wire to cut the grass safely. Our significant benefits of this project include that it is a wireless grass cutter means no need for the externally connected wires. The system uses batteries to operates and automatically charge with the solar energy to save and reduce the electrical cost. The grass patterns can be easily drawn with one click, and have a minimum chance of error.

Technical Details of Final Deliverable

The proposed systems will be designed as a lab-scale prototype to experimentally validate the efficiency, accuracy, and affordability of the systems. The experimental results will prove that the proposed work has all in one capability (wireless, automatic pattern based grass cutting, and energy saving) is very easy to use, and can be easily assembled in a simple hardware circuit. We remark that the proposed systems can be implemented under real conditions at large-scale in the future, which will be useful in smart cities applications.
