ABSTRACT. The project aims to produce a machine which would relieve people from a regular task of cutting grass in their garden. Automated lawn mouser Bluetooth control are presently available to the public, e.g. [2], but the low spread of these devices is mainly due to the cost which start at £918.13 [3]. The goal of this project is therefore to produce a similar device with similar (if not better) performance, at a significantly lower cost. The present report will provide an understanding the sensor selection process, an analysis of the microcontroller to be used and the relevant functions it has to execute, a study of the relevant motors used and a system overview. Nowadays, Lawnmouser r is used to make human‘s life much easier to do lawn mowing. As user can see today, most people still use man pouser r on cutting grass. This project is an invention and a way to make human life become easier which is they can save their time. These following are the problems are occurred and the reasons why people rarely use this smart grass cutter..

INTRODUCTION. 1.1 Introduction The main aim of this project is to provide a method for designing automatic lawnmowers whose job is to cut grass according to specific patterns without the need for user intervention. The task done should be possible using a sensor that provides distance measurement to the microcontroller. Further more the device can be used to decide the way to follow, work out its situation, and stop when the task is finished, as shown in Figure 2 . Besides ,the venture likewise expects to deliver a machine which would computerize individuals from a standard errand of cutting grass in their nursery. Computerized lawnmower is right now present and accessible to the general population, e.g.[4] yet the low accessibility of these gadgets is predominantly because of the expense what begin is extremely high as far as valuing [4]. At last, the objective of this venture is along these lines to create a comparative gadget with comparative (while possibly worse) execution, for an essentially minimal price. The objective of this report is to analyze an overview of the components selection process, an analysis of the microcontroller used and the associated functions it needs to perform, an investigation of the associated motors used and an overview of the system. However, some areas are incomplete in this progress report. Automated Lawnmower available from to general public for over 30 years [2] ; Meanwhile, the availability of this device is limited to the access of public. The current technologies sell for around high prices and given the manual versions of these devices, standard lawnmowers selling. There are various certifiable advantages of having a machine that autonomously cuts grass, these include: To ensure people uses less effort for mowing To enable users a more beneficial and effective mowing method It's a device that fits almost every lifestyle, so having a low-cost device while doing the same job as a high-end model to compete with the current market is a big advantage. End users want to enjoy the benefits. The aesthetic value around him is as important to modern people as food and shelter. In general, grass is known to survive. In a variety of conditions, so from should limit growth in to enhance the beauty of the habitat. As man evolved intellectually, grass cutting inevitably developed to an art..

RESEARCH BACKGROUND. It is a device that can fit into just about everyone's lifestyle, therefore having a device that costs less, whilst accomplishing the same task as the higher end models is a great advantage in order to compete with the current market where the end consumer will benefit from. The aesthetic value of his environment is as important as food and shelter to the modern man. In general, grasses are found to survive in a variety of conditions and thus the need to curtail their growth in order to enhance the beauty of our habitat environment. As man evolved intellectually, grass cutting inevitably developed to an art. As technology advanced grass cutting developed, away from use of machetes, hoes and cutlasses to motorized grass cutters. Technology had continued to advance and better techniques of grass cutting has been invented and constantly improved upon. This gave birth to the invention of lawn mouser r. A lawn mouser r is a machine used for cutting grass or lawns. A lawn is any area of grass; mostly tough grass which is neatly cut like in a private garden or a public park. The first lawn mouser r was invented in 1830 by Edwin Beard Budding (www.altavista.com/history). He was said to obtain the idea after watching a machine in a local cloth mill which used a cutting cylinder mounted on a bench to trim clothes for a smooth finish after user aving . Budding realized that a similar concept could be used to cut grass if the mechanism is mounted in a wheel frame to enable the blades rotate close to the lawns surface [1]. These early machines user re made of cast iron and featured a large rear roller with a cutting cylinder (reel) in the front. Cast iron gear wheel transmitted pouser r from the rear roller to the cutting cylinder. In 1832, Ransoms of Ipswich (under license) began the making of Budding’s mouser r. This company is today the world’s largest manufacturer of lawn care equipment. By mid 1850, Thomas Green developed a mouser r which used chains to transmit pouser r from the rear roller to the cutting cylinder [2]. It was called ‘ Silens Messor ’ meaning silent cutter. The machines user re found comparatively lighter and quieter than the gear driven machines that preceded them. By late 1890, motorized mouser rs appeared as light user ight petrol engines and small steam pouser r units became available. In US, Colonel Edwin George produced the first gasoline pouser red mouser r in 1919. Electric pouser red mouser rs and rotary cutting machines emerged in the 1920’s and 1930’s [2]..

PROBLEM STATEMENT. Nowadays, Lawnmower is a machine used to make human ‘s lifestyles a lot easier to do garden mowing and also general moving. As many users can see nowadays, most people still use manpower on cutting grass [4]. This project is an invention which can be used to make human life turn out to be less complicated which in return can save their time [3]. These following are the issues that are passed down and the reasons why humans not often use this smart grass cutter [2].There are many designs has been made in the marketplace, each design has a particular purpose. The small lawnmower types are suitable for small residential lawns and garden, whilst larger, self-box or trip-on mouser are appropriate for huge lawns [4]. Usually, time to use to reduce the lawn is longer, depending on how big the scale of the garden. Moreover, the device needs plenty of manpower to behavior so that the gadget might be in its position. With this invention this is computerized lawnmower, it simply spends approximately five minute to installation and left the gadget to finish the task [5].Besides that, the value cut grass is costly which incorporates the fee of hiring human beings, gasoline, and renovation. This invention will assist in lowering this cost where it'll lessen to the most stage [6]. Herewith the aid of using the smart grass cutter there may be no need to use the gasoline. No fuel method, no emission, and no pollutants. There is 0% of exhaust emission in this gadget.

RESEARCH QUESTIONS. The Research questions of this project are: 1. Can evaluate the lawn mower blade efficiency compare with manual grass cutting method ? 2. Can interface with Bluetooth module connectivity with Arduino Uno communications ? 3. Can evaluate the efficiency of lawn mower movement among various landfills ?.

RESEARCH OBJECTIVES. For this project it focuses more on domestic use [8]. The machine is use for cutting grass on the house lawn. It also needs a border wire as a guide for the machine to work inside the border wire. This machine use IR detector to detect any obstacle like small rock, object within certain distance [6]. As an addition, metal detector also is use to detect metal in certain distance. Last but not least, voltage indicator is use to indicate the amount of battery left whether it need to be recharge for the machine to work [7]. I. Bluetooth Module This project uses Bluetooth module to interface between user and system. User command will be convey by Bluetooth module act as a bridge between both system and user. It can be transmitting command from a 1 to 3 meter radius in a specific lawn area. II. Blades In this cutting grass machine, cable ties as the blade because it is easy to be replace and can get it anywhere. Furthermore it is light and has more safely because it is not sharp when handle it during the changing the cable. III. Battery Multiple batteries Lipo under 3V-12V in the smart grass cutter. This battery will be used to save and generate the machine. This battery can be recharge. IV. Chassis Light material which is acrylic board. It is covered by plastic cardboard..

MANAGEMENT THEORY / MODEL. There are basically two different lawn mower types: reel mowers and rotary mowers. Reel mowers make precise clean cuts on grass blades using the scissor-like action of a cylinder of rotating blades. They may have 2-6 of these rolling blades which are usually turned by the axle of the mower’s wheels. Available as tow behind attachments for lawn tractors, gas or electric powdered or manual push models, reel mowers are generally less noisy and create less pollution than rotary mowers. Reel mowers can also cut grass to short heights better than rotary mowers. However, reel mower blades can be difficult to sharpen and maintain. Rotary mowers usually have one blade which rotates very fast. Rotary Mower is a mower in which the blade spins horizontally (east to west) and uses a sucking and tearing action to cut the blades of grass. The design is simple and adapts very well to small engines. Rotary mowers can cut a wide variety of grass conditions. There are usually powered by gas engines or electric engines and the most common mowers used by home owners. Among those are as shown in Table 1..
