1.INTRODUCTION
A lawn mower is a machine that is used to cut grass
in a lawn. The blades of the lawn mower are generally
powered by pushing the mower forward. Lawn mowers are
classified based on different criteria. For example,according
to the axis of rotation of blades we may have reel lawn
mowers (in which the axis is horizontal) and rotary lawn
mowers (in which the axis is vertical).The reel (cylindrical)
lawn mower is found to be better. Rotary mowers are often
powered either by an internal combustion engines or an
electric motor and are generally mowed manually, with the
engine only spinning the cutting blades. Rotary mowers are
generally have opening by the side of the housing through
which cut grasses are expelled. Some are attached with a
grass collector at the exit point. The blade is seldom sharp
enough to give a neat cutting point. The bladesimplycutsthe
grass resulting in brown tips. Over the years, there have
been numerous developments in lawn mower technology.
But with technological advancement there also arises the
need to check the impact of machines on the environmentas
well as on man. Pollution is the major concern with the
conventional gas powered lawn mower. Human effort is
another factor that needs to be reduced. Solar Powered
Lawn Mower it is the design of a microcontrollerand sensor
based robotic lawn mower mechanism. Thisroboticmowing
device is solar powered and its battery gets charged from
sunlight while mowing on the lawn or even manually.
Ultrasonic sensors is used for avoiding obstacles.Thisdesign
is targeted as an alternate green option against the popular
but environmentally hazardous gas powered lawn mower.
The design is built on a mobile robot which communicates
with a smartphone through aBluetoothmodule.mowerrobo
uses solar energy with the help of a solar panel and solar
photovoltaic cells to run an electric motor. Also this mover
robo can be used automatically by using arduino and
ultrasonic sensor for obstacle detection.
We performed detailed analysis to estimate the torque
produced in the blade and whether it is sufficient to perform
the intended job. After design and development of the lawn
mower, it is tested on four different species of grass. We
tried to develop a height adjustable mechanism for the
cutting blade.

Arduino is an open-source electronics platform based on
easy-to-use hardware and software. Arduinoboardsareable
to read inputs - light on a sensor, a finger on a button, or a
Twitter message - and turn it into an output - activating a
motor, turning on an LED, publishing something online. You
can tell your board what to do by sending a set of
instructions to the microcontroller on the board. To do so
you use the Arduino programming language (based on
Wiring), and the Arduino Software (IDE), based on
Processing.
In this Automated mower robo arduino is as main
microcontroller for this robo. The Bluetooth module and
ultrasonic sensor is connected to this board on digital and
analog pins. With proper programming on arduino board
mower can be used automatically.

2. Open source and extensible software
3. Simple, clear programming environment
4. Cross-platform
5. Inexpensive
3.2 ULTRASONIC MODULE SENSOR :
An Ultrasonic sensor is a device that can measure
the distance to an object by using sound waves. It measures
distance by sending out a sound wave at a specific frequency
and listening for that sound wave to bounce back. By
recording the elapsed time between the sound wave being
generated and the sound wave bouncing back, it is possible
to calculate the distance between the sonar sensor and the
object.

3.4 BATTERY
Batteries are available in various volts and ampere
hour range. To determine the one to use, consideration was
given to the voltage and the ampere hour rating.,12Vbattery
was selected. The ampere hour measures the length of time
the battery will discharge while in use and is not charging.
1.3ampere hour battery will givea 1.3amp of currentforone
hour and the current required by the motor is lessthan that.
We used one motor of 420mAh and four motors of 220mAh
in which two motors are in series with other two motors.
220+220+420 = 860mAh< 1300mAh
Fig -5: AUTOMATED MOWER ROBO WORKING
4. DESIGN ANALYSIS :
In designing the cutting blade, the force required to
cut the lawn as well as the force acting on the blade was
considered. The force required by any sharp object to have
impact on the grass is less than 10 Newton. It is also
dependent on the height, density and the areacoveredbythe
object (Atkins, 1984). Therefore, in designing the blade of
the solar powered lawn mower, the force required for
effective mowing should be greater than 10 Newton. A
stainlesssteel is used in the construction of the cuttingblade
because of its strength and weight which can transmit same
speed as that of the DC motor or a little less cause of friction.
Shearing force of most annual grasses found on most lawns
is usually between 9.2N to 11.51N.
Force required by cutting blade to shear the grassisgivenby
F=T/R, where T= shaft torque
R=radius of cutting blade= 0.075m
T= P/(2*3.14*N) where P= power developed by shaft
N=Speed of motor=1450 rpm
P= V*I = 12*420= 5040W
T= 5040/6280= 0.8025 Nm
F= T/R = 0.8025/0.075 =10.7 N
Which is in given range
SOLAR PANEL CALCULATION:
VOLT = 12 V
WATT = 5 W
W = V X I
5 = 12 X I

The solar powered lawnmower is designed and developed.
Test is carried out using four species of grass and the result
obtained is summarized aspresented in Table 1. FromTable
1, the average height of the grasses after mowing is lesser
than the expected after the machine is adjusted to a height
for the four species of grasses. Less time is spent in cutting
the grasses. The efficiency of the machine is found 90%.
6. CONCLUSION :
In the world today, all machines are designed with
the aim of reducing or eliminating greenhousegasemissions
which is the major causes of climate change. This solar
powered lawn mower will meet the challenge of
environmental production and low cost of operation since
there is no cost for fueling. A solar powered lawn mowerhas
been developed for the use of residences andestablishments
that have lawns where tractor driven mowers could not be
used. The machine’scapacity isadequateforitspurpose.The
machine has proved to be a possible replacement for the
gasoline powered lawn mowers.

Also this mover Robo can be used automatically by using arduinoand ultrasonic sensor for obstacle detection. We performed detailed analysis to estimate the torque produced in the blade and whether it is sufficient to perform the intended job. After design and development of the lawn mower, it is tested on four different speciesof grass. We tried to develop a height adjustable mechanism for the cutting blade.

Ultrasonic Sensor module 3.1 ARDUINO UNO : Arduino is an open-source electronics platform based on easy-to-use hardware and software. Arduinoboardsareable to read inputs - light on a sensor, a finger on a button, or a Twitter message - and turn it into an output - activating a motor, turning on an LED, publishing something online. You can tell your board what to do by sending a set of instructions to the microcontroller on the board. To do so you use the Arduino programming language (based on Wiring), and the Arduino Software (IDE), based on Processing. In this Automated mower robo arduino is as main microcontroller for this robo. The Bluetooth module and ultrasonic sensor is connected to this board on digital and analog pins. With proper programming on arduino board mower can be used automatically. Fig -2: ARDUINO UNO Why Arduino : 1. Open source and extensible hardware 2. Open source and extensible software 3. Simple, clear programming environment 4. Cross-platform 5. Inexpensive 3.2 ULTRASONIC MODULE SENSOR : An Ultrasonic sensor is a device that can measure the distance to an object by using sound waves. It measures distance by sending out a sound wave at a specific frequency and listening for that sound wave to bounce back. By recording the elapsed time between the sound wave being generated and the sound wave bouncing back, it is possible to calculate the distance between the sonar sensor and the object.

Fig -4: BLUETOOTH MODULE 3.4 BATTERY Batteries are available in various volts and ampere hour range. To determine the one to use, consideration was given to the voltage and the ampere hour rating.,12Vbattery was selected. The ampere hour measures the length of time the battery will discharge while in use and is not charging. 1.3ampere hour battery will givea 1.3amp of currentforone hour and the current required by the motor is lessthan that. We used one motor of 420mAh and four motors of 220mAh in which two motors are in series with other two motors. 220+220+420 = 860mAh< 1300mAh Fig -5: AUTOMATED MOWER ROBO WORKING 4. DESIGN ANALYSIS : In designing the cutting blade, the force required to cut the lawn as well as the force acting on the blade was considered. The force required by any sharp object to have impact on the grass is less than 10 Newton. It is also dependent on the height, density and the areacoveredbythe object (Atkins, 1984). Therefore, in designing the blade of the solar powered lawn mower, the force required for effective mowing should be greater than 10 Newton. A stainlesssteel is used in the construction of the cuttingblade because of its strength and weight which can transmit same speed as that of the DC motor or a little less cause of friction. Shearing force of most annual grasses found on most lawns is usually between 9.2N to 11.51N. Force required by cutting blade to shear the grassisgivenby F=T/R, where T= shaft torque R=radius of cutting blade= 0.075m T= P/(2*3.14*N) where P= power developed by shaft N=Speed of motor=1450 rpm P= V*I = 12*420= 5040W T= 5040/6280= 0.8025 Nm F= T/R = 0.8025/0.075 =10.7 N Which is in given range SOLAR PANEL CALCULATION: VOLT = 12 V WATT = 5 W W = V X I 5 = 12 X I

RESULTS AND DISCUSSION : Table -1: Calculated Results Sample plot Height average height of the grass before mowing (mm) Average average height of the grass after mowing (mm) Average Expected height of the grass after mowing (mm) Average Elephant grass 230 80 90 Stubborn grass 234 84 90 Spare grass 111 80 80 Carpet grass 70.5 - - The solar powered lawnmower is designed and developed. Test is carried out using four species of grass and the result obtained is summarized aspresented in Table 1. FromTable 1, the average height of the grasses after mowing is lesser than the expected after the machine is adjusted to a height for the four species of grasses. Less time is spent in cutting the grasses. The efficiency of the machine is found 90%. 6. CONCLUSION : In the world today, all machines are designed with the aim of reducing or eliminating greenhousegasemissions which is the major causes of climate change. This solar powered lawn mower will meet the challenge of environmental production and low cost of operation since there is no cost for fueling. A solar powered lawn mowerhas been developed for the use of residences andestablishments that have lawns where tractor driven mowers could not be used. The machine’scapacity isadequateforitspurpose.The machine has proved to be a possible replacement for the gasoline powered lawn mowers.
