I. INTRODUCTION

The Automated Guided Vehicle (AGV) is a general one that incorporates all vehicle structures fit

for working without driver action. Robotized guided vehicles have found colossal present day

applications. AGVs are right now found in a wide scope of adventures, with the principle

constraints on their usage basically coming about due to the segments of the items to be

transported or spatial thoughts. Various employments of AGVs are really feasible, yet the purchase

and execution of such systems is for the most part established on money related examinations.

In an ordinary conveyance community, human prosperity administers the productivity. The AGV

is uncommonly versatile in light of remote correspondence. Its ability to talk with various

autonomous vehicles gives a predictable action. Persevering coordination between vehicles passes

on money saving viability. The introduction of unmanned vehicles onto a stockroom floor effects

influences security. With the guide of natural sensors, the AGV can recognize inquiries in its

accident way. Computerization abstains from vehicle car over-burdens and their potential for

disasters.

II. LITERATURE REVIEW

The first Automated Guided Vehicle was acquaint with the world in 1950s and the first large

advancement for the AGV business was the presentation of a unit load vehicle in the mid 1970's.

Suman Kumar Das, M.K. Pasan

Right now kinds of aides methods for AGV's are examined. The sorts are Wire Guided Vehicle,

Magnetic Guided Vehicle, Rail Guided Vehicle and Laser Guided Vehicle. In Wire Guided

Vehicles wires are simply utilized for the transmission of radio sign to direct the vehicle along the

way chose. A space is sliced in to the floor and a wire is put around 1 inch underneath the surface.

This space is cut along the way the AGV is to follow. This wire is utilized to transmit a radio sign.

A sensor is introduced on the base of the AGV near the ground. The sensor distinguishes the

overall situation of the radio sign being transmitted from the wire. This data is utilized to direct the

controlling circuit, causing the AGV to follow the wire. [1].

Hee-Woon, Hwally Lee

Right now recognition and situating is proposed. AGV ought to explore the way accurately which

is requested by the administrator, and it ought to likewise maintain a strategic distance from the

obstructions coming in the middle of for example in a distribution center if a laborer goes over the

way of AGV, it ought not slam into the specialist, it is possible that it should pass by the specialist

by finding another way breaking down the encompassing or it should stop for some time and hold

up until the laborer passes. Now and again a minimal effort camera is added to catch the ongoing

pictures to figure out the encompassing to keep away from crashes. By the blend of profundity

data from the picture taken by the camera and 2D facilitate framework would be useful to

ascertain the constant separation along AGV's, gear and articles precisely to decrease position

mistake. [2].

Lothar Schulze, Sebastian Behling and Stefan Buhrs

Right now improvements and consequences of research are examined. Segments of AGV are

vehicle, stationary control framework, fringe framework parts and on location framework

segments. Vehicle is the fundamental control component of the AGV and plays out the real

transportation task which is requested. Stationary control framework is the organization of

transportation request. Enhancement of calendars and the board of multi AGV framework is

overseen by stationary control framework. Fringe framework parts speak to the partner to different

on board gear of the vehicle, for example battery stacking stations and burden move systems. On

location framework parts are the parts of the site's basic plan that affects the AGV, for example the

ground, doors, lift, etc. [3].

Himanshu Dudeja, Laxman Bagal, Nityanand Zunjur, Prof. S.S. Jagadale

Right now sensors and their working is clarified. The fundamental sensors of AGV are attractive

guide sensors, normally known as MGS1600 and Motor controller sensors known as FBL2360 and

2CHBLDC. The MGS1600 is an attractive guide sensor fit for recognizing and revealing the

situation of attractive field along its flat hub. The sensor is proposed for line following automated

applications utilizing an attractive tape to shape a track direct on the floor. FBL2360 has various

wellbeing highlights which are joined into the controller to guarantee solid and safe activity. [4].

III. HISTORY

Essential Automated Guided Vehicle innovation is definitely not another innovation. Fifty years

prior when AGV's were first utilized they were called driverless frameworks. After certain years,

headways in gadgets have prompted changes in the vehicles. In any case, structuring an AGV that

can really move and capacity isn't a simple errand. The vast majority of them in ventures are

worked utilizing electric force and moved by the utilization of electric engine. The engine is

additionally associated with gears by means of a pole and afterward to the wheels for speed

varieties. Through this system the AGV can move to the necessary way. In light of these elements,

the connection between absolute loads that the AGV can withstand with the force provided is

significant.

As we as a whole realize we are the age which is going to observe the fourth modern insurgency

which is going to make a huge difference we have now. Right now, significant level ICT's

(Information and Communication Technologies, for example, AI (Artificial Intelligence), IOT

(Internet of Things), Big information, cloud framework will prompt creative change on the planet

yet the greatest and most significant change will happen because of the Automatic Driving. An

AGV represents Automated Guided Vehicle or Automatic Guided Vehicle as the name

recommends is the vehicle guided on a fixed way on administrator's order with the assistance of PC

programs and without the human help which was created by Barrett Electronics Corporation

designed the world's first AGV for mechanical application in 1950s. The first AGV was brought to

advertise in the 1954. Around then it was just a tow truck that followed a wire in the floor rather

than a rail. Over the rails of innovation has gotten increasingly complex and today computerized

guided vehicles are basically laser explored.

IV. TYPES OF AGV AND NAVIGATION

Robotized guided vehicle frameworks comprise of the PC, programming and innovation that are

the "cerebrums" behind the AGV. Without PC programming frameworks and correspondences

systems, just the most straightforward AGV capacities can be performed.

• Camera guided AGVs are utilized when exact direction precision is required, for example, in

swarmed situations and littler measured offices. An on-board camera centres and guides the AGV

while performing.

• Forked AGVs are utilized to get and convey different burdens, for example, beds, trucks, rolls

what's more, others. These can be physically determined just as utilized consequently, and have the

capacity to lift burdens to numerous levels.

• Inertial guided AGVs utilize a magnet detecting gadget, a gyrator that gauges the unit's

heading and a wheel odometer that ascertains the separation voyaged. Magnets mounted

underneath the floor are identified by the on-board attractive detecting gadget and join with the

initial two readings to give an exact positional area. Another type of AGV direction is interial

route. With this direction, a PC control framework guides and relegates undertakings to vehicles.

Transponders are inserted in the floor of working environment. The AGV utilizes these

transponders to confirm that the vehicle is on course. A spinner can identify the scarcest alter in the

course of vehicle and amends it so as to keep the AVG on its arrangement.

• Large case/unit load AGVs are utilized to ship heavier burdens with different exchange

gadgets, for example, roller beds, lift/lower components and custom instruments.

• Laser guided AGVs utilize mounted laser scanners that radiate a laser and reflect once more

from targets. The vehicle's area can be resolved dependent on separation to the objective and time

of reflection data. The route is finished by mounting considering tapes dividers, shafts ,and so on

the AGV conveys a laser transmitter and recipient on a pivoting turret. The laser is transmitted and

gotten by a similar sensor. This data is contrasted with the guide of reflector format put away in

AGVs memory. The present position is contrasted with the way modified in to the reflector design

map. The controlling is balanced as needs be to keep the AGV on target. It can then explored to an

ideal objective utilizing the continually refreshing position.

• Optical guided AGVs utilize a latex-put together photosensitive tape with respect to an office's

floor for direction. Separation is estimated by utilization of wheel odometers, which set up stop

areas for the AGV along the course.

• Outrigger AGVs have two even balancing out legs (outriggers) to offer sidelong help, and are

utilized to deal with beds, rolls and racks.

• Small undercarriage AGVs can move through jam-packed work environments through laser

detecting, while at the same time moving littler burdens.

• Smart vehicle AGVs are fit for deciding their own traffic control and steering without requiring a

focal controller.

• Tug/tow AGVs are utilized to pull trailers and are normally kept an eye on by an administrator

who includes and evacuates the trailers at assigned stops. These can follow a fundamental circle or

a progressively entangled way.

• Wire guided AGVs utilize a charged wire that is covered underneath the floor for appropriate

direction and has little reception apparatuses made out of metal curls mounted on their bottoms.

The more grounded the field between the covered wire and radio wires, the higher the voltage

incited to the loops. A space is cut into the floor and wire is set roughly 1 inch underneath the

surface. This space is cut along the way the AGV is to follow. This wire is utilized to transmit a

radio sign. A sensor is introduced on the base of near ground. The sensor distinguishes the general

situation of radio sign being transmitted from the wire. This data is utilized to direct the controlling

circuit, causing the AGV to follow the wire.

• Natural Navigation without retrofitting of the workspace is called regular focusing on route.

One technique utilizes run discovering sensors, for example, a laser run discoverer, just as

whirligig. The upside of such framework is that they are exceptionally adaptable or on request

conveyance to any area. They can deal with disappointment without cutting down whole

assembling activity, since AGVs can design ways around the bombed gadget. They likewise rush

to introduce, with less vacation for the plant.

• Guide tape AGVs tape for control way. The tapes can be of two sorts: attractive or hued. The

AGV is fitted with the suitable guide sensor to follow way of the tape. One significant bit of

leeway is that it very well may be effectively expelled and migrated if the course needs to change.

Shaded tape is at first more affordable yet comes up short on the benefit of being inserted in high

rush hour gridlock zones where the tape may get harmed or grimy.

Research on these vehicles is on-going, and new advancements on programming and development

systems are as often as possible being made.

V. WORKING OF AGV

A. Steering Control

To help AGV explore it can utilize three diverse cow control frameworks. The differential speed

control is generally normal. Right now are two free drive wheela. Each drive is driven at various

speeds so as to turn or a similar speed to permit the AGV to go advances or in reverse. The AGV

turns along these lines to a tank. This strategy for controlling is the most straightforward as it

doesn't require extra directing engines and system. As a general rule, this is seen on an AGV that is

utilized to ship and turn in tigh spaces or when the AGV is working close to machines. This

arrangement for wheels isn't utilized in towing applications in light of the fact that the AGV would

make the trailer folding blade when it turned.

The second kind of guiding utilized is directed wheel control AGV. This sort of controlling can be

like vehicle's directing. Be that as it may, this isn't entirely flexibility. It is more exact in the

accompanying modified way than the differential speed controlled strategy. This sort of AGV has

smoother turning. Directed wheel control AGV can be utilized in all applications; dissimilar to the

differential controlled. Directed wheel control is utilized for towing and can likewise now and

again have an administrator control it.

The third sort is a blend of differential and guided. Two autonomous cow/drive engines are set on

slanting corners of the agv and swiveling castors are set on different corners. It can turn like a

vehicle toward any path. It can crab toward any path and it can drive in differential mode.

B. Steering Mechanism

• Ackerman’s Steering Mechanism

• Variable Speed Motors

• Additional wheels for Steering

Among the three sorts recorded, we have picked Ackermann Steering Principle which is

additionally guided by rack and pinion so as to accomplish an exact controlling for the Automated

Guided Vehicle. Ackermann Steering Geometry is a geometric game plan of linkages in the

controlling of a vehicle or other vehicle intended to take care of the issue of wheels within and

outside of a go expecting to follow out circles of various radii.

F. Sensors

Collision: Two dynamic low knock sensors are situated on the rear of the robot. They are wired in

equal, and the yield is attached to a low need intrude. The hinder is designed to a falling edge. If

the hinder is terminated, the AGV forever stops.

Obstacle Detection: Despite the fact that there was no requirement for people in the robotized

stockroom, individuals could be unusual (not normal for robots). Separation sensors decided

whether an article was in the forward way of the vehicle. In the event that they distinguished

something, the robot would stop before verifying whether the impediment was as yet present. For

clear reasons, the sensors were incidentally incapacitated when the AGV was drawing nearer the

racks. While backing up, the back knock sensors were initiated so a back crash could be identified.

On the off chance that this occasion happened, the vehicle would be for all time handicapped.

VII. PROGRAMMING For programming purpose, the following components are used;

1) Software components

a) Raspbian OS:

It is a Debian-Linux based operating system for Raspberry Pi. It is highly optimised for

Raspberry Pi’s low- performance ARM CPUs. It is very lightweight and makes a great

choice for Raspberry Pi. It includes tools for browsing, python programming and GUI

desktop. Its desktop environment is known as LXDE(Lightweight X11 Desktop

Environment).

b) Python:

Python is an interpreted programming language, which supports both Object Oriented and

Procedural programming. Its syntax is very clean and easy to understand. As Raspbian OS

already include Python programming tools, and also because of its capability to connect to

real world, it is chosen as the language for project development.

2) Hardware Components

a) Raspberry Pi microprocessor:

Raspberry Pi has been chosen to be used the main processing system. It will be responsible

for controlling all sensors, gathering data, processing it, and giving appropriate commands to

the drive system.

b) Ultrasonic Sensor:

Ultrasonic sensor is used to find out the distance between whatever object is present in

front of the AGV. It works on the principle of sound waves.

c) Infrared Sensor:

Infrared sensor is used to check the existence of an obstacle in the AGVs proximity. The

output given is digital.

d) Motor driver:

Motor driver is used for interfacing the motor with the microprocessor, so that the

microprocessor can control its speed.

Ultrasonic sensor(HC-SR04)

• We are using Ultrasonic sensor HC-SR04 for distance measurement.

• The sensor works on basic principle of sound waves , the sensor gets a trigger from the

microprocessor , it produces a sound wave , the wave bounces off the object and gets

reflected . then the receiver or ECHO pin detects the reflected wave.

• By programming , the start and end time of the pulse is recorded, and as the speed of

sound is known , the distance between the object and the sensor can be known(which is half

the distance travelled by the wave)

• This sensor has a higher range , but low accuracy , because sound waves bounce on any

surface and the there is no way to know exactly how the waves are returning .

• Also , when object is moving the sensor tends to give erratic results after the first few correct

readings.

This sensor has slightly complicated setup , as a few resistors are needed to adjust the

voltage and also to protect the sensor from burning out.

Test results for sensor

• At long range(100cm) only sufficiently large objects have right distances produced, for

small objects, the readings are either erratic or null.

• At medium range(40-60 cm) most objects are correctly detected, but curved/small objects

may give erratic readings.

• At short range(10-20cm) all objects get detected with acceptable accuracy.

• Error at long range is 6-10cm , at medium range is 2-10cm, and at short range is 0-3cm.

• Basically, the reading for an object is highly dependent on its size, material, and

orientation.(if object is tilted at an angle, readings become erratic)

• Also, readings may stop when object is brought extremely close.

Infrared sensor

• The sensor produces the output as HIGH or LOW (0 or 1, digital output). When the object

is in range the result is 0 while the object is away the output is 1.

• The working of the sensor is subject to light conditions.

• The sensitivity of the sensor is also subject to the size of an object, for eg: a large object

like a box gets detected at a distance of approximately 15-17 cm, but a thin object like a

pen gets detected at a much closer distance.

• The sensor actually produces an analog voltage as output which is subject to the objects

distance , but is converted to digital output .

• It was also found that the detection range of the sensor can be altered to some extent

using the adjustment screw.

To acquire actual distance measurements , firstly the digital output (0 or 1) has to be

converted to analog output (voltage). For this , an

A.D.C.(analog to digital converter) can be used.(Eg:

M3008 ADC)

If this is not done, the sensor can still be used to detect the presence of an object. But the

distance cannot be understood.

Test results for sensor

• The infrared sensor module can be calibrated for its range.

• 2 calibrations were studied, short and long range.

• Before studying the data, it should be noted that as the sensor works on light principles, the

readings differ according to objects colour and reflectivity.

• Considering this, black coloured and objects become the worst case (lower bound) while

white or reflective objects become best case(upper bound).

• For long range calibration, normal objects get detected between 25-35cm from sensor,

Black objects at 10-15cm, and white/reflective objects between 30-60 cm.

• For short range calibration, normal objects get detected between 15-20cm from sensor,

Black objects at 5-8cm, and white/reflective objects between 25-50 cm.

• Basically, detection is dependent on size, colour and reflectivity of object.

Motor interfacing

• The AGV wheels will be driven by 5V DC motors, which will be controlled by the

Raspberry Pi microcontroller.

• For interfacing the motor, a driver module is needed. We have used the L293D motor driver.

• The motor is connected to the driver, and the driver to RPi. Also a power source is needed.

(In our case of testing we took power from raspberry pi itself)

• For controlling speed of motor, pulse width modulation technique is used. PWM is

implemented in program using inbuilt library GPIO.PWM in Python/Raspbian OS.

Combination

• An attempt was made to combine sensors and motor to work in unison.

• 2 IR sensors(Long and short range), Ultrasonic sensor, and 5V motor were connected to

RPi, and were programmed according to requirements.

• The working is as follows,

• Long range IR detects obstacle and lowers speed .

• Short range IR detects obstacle and stops vehicle, triggers US sensor.

• US sensor is activated and distance is measured.

• If obstacle moves away, the motor starts working again at low or high speed according to

proximity.

• Also, short range infrared sensors MAY be setup on the corners (front and back) which

will help in parking, charging, and extreme proximity scenarios.

VIII. BENEFITS OF AGV

Companies that utilization AGVs, frequently processing plants, distribution centers, emergency

clinics and other huge offices, advantage from the numerous favorable circumstances AGVs bring

to the table. One of the most advantageous is decreased work costs.

AGVs don't tire like human laborers, and when their batteries are depleted, charging the AGVs

effectively recharges their vitality. Burdens that AGVs convey are far heavier than any single

human could oversee, which makes shipping substantial items snappy and basic. AGVs help give

organizations a serious edge since they increment profitability and complete the activity in a

compelling and time-proficient way. They are adaptable and can be adjusted to a wide range of

necessities. Likewise, utilizing AGVs diminishes harm to items and builds security among

laborers. Some run of the mill preferences of any AGVs can be pin highlighted:

• Reduced work and related expenses.

• Increased reliability and profitability.

• Fewer items taking care of harm.

AGVs are seen as adaptable, secluded and flexible. Notwithstanding, the disappointment of a

portion of the establishments, and the consequent examination of the explanations behind

disappointment, shows that cautious structure and operational arranging of AGV-based material

taking care of frameworks is required if the maximum capacity of such a framework is to be

figured it out.

IX. APPLICATIONS

The primary application zones are association of various work territories, request picking,

warehousing and get together. The acknowledgment of the material stream forms in the

warehousing and request picking division is portrayed by high volume of traffic from characterized

sources to characterized goals. This is a standard application region of AGVS which as a rule

requests high stacking limits. The heap units are generally institutionalized beds, consequently the

vehicles are outfitted with standard stacking gadgets. Because of the mentioned exhibition, these

frameworks regularly comprise of in excess of 100 vehicles. This requests a modern focal

controlling unit and advancing methodologies for directing and way finding.

Another region with a high application pace of AGVS are mechanical production systems. Right

now load is inhomogeneous and evolving. In this way the stacking gadgets must be fitted to the

particular application. The vehicle once in a while not just vehicles the heap starting with one get

together station then onto the next, yet speaks to a gathering station itself. Right now vehicle can be

considered as a portable workbench.

AGV can be utilized in a wide assortment of uses to ship a wide range of kinds of material

including beds, moves, racks, trucks, and holders. Following are the applications:

Taking care of crude materials: AGVs are ordinarily used to move crude materials, for example,

paper, steel, elastic, metal and plastic. This incorporates shipping materials from recieveing to the

distribution center, and conveying materials straightforwardly to creation lines.

Work-in-process development: it is one of the primary applications where mechanized guided

vehicles ere utilized and incorporates the tedious development of materials all through the

assembling procedure.

Bed dealing with is amazingly mainstream utilization of AGVs as redundant development of beds

is basic in assembling and appropriation offices. AGVs can move beds from palletizer to extend

wrapping to the distribution center.

Holder taking care of: AGVs are utilized to move ocean compartments in some sea holder terminal.

Productive, practical development of materials is a significant and normal component in improving

activities in many assembling plants and stockrooms. AGVs can be applied to different enterprises

in standard plans to best suit in an industry prerequisites.

The principle center is revolved around PC vision and its useful combination into an AGV-System.

Exploratory outcomes show great exhibitions of the framework. Strategic activities like request

picking would gigantically benefit from such a capacity. An intriguing point of view is a stockroom

with workers concentrating on picking while trolleys are following naturally. At the point when

they are completely stacked the trolleys will convey their heap to the goal point. Void substitutions

are given by the focal control in time.

A lot progressively new applications for AGVS can be found in the coordinations part. A model is

the usage of an AGV to a stationary bed stretch wrapping gadget. Along these lines makers can

dispose of the utilization of bed transports, decrease work costs, increment plant ground wellbeing,

and dispense with item and transport harm brought about by human blunders.

X. RESULTS AND DISCUSSION

The AGV is an efficiency expanding highlight in a plant. During planning this AGV we have given

the essential capacities like line follows and impact keeping away from. Also, the primary

capacity, transportation of merchandise from station to station. The followings are the principle

highlights of the model which we have planned.

1. Speed of conveyance

2. Modification of vehicle speed

3. Adaptability of way

4. Versatile to changes in industrial facility formats

5. Maintain a strategic distance from crash with different items

6. Decrease in labor cost

7. Decrease in running expense contrasted with transport frameworks

8. Capacity to add sensors to identify the payload conditions

9. Proceeds with pattern of working

10. Conditions for line following can be changed without any problem

XI. CONCLUSIONS

Mechanized guided vehicles assume a significant job in adaptable assembling frameworks. The

task primarily manages working of an AGV and controlling it with PC. The disentangled plant

format is considered in the work and the vehicle is effectively controlled from one machine unit to

the next with machine number as the main info.

There are a few potential headings for additional examination. We can improved the guided tape

type AGV using better route strategy. It tends to be embraced any condition and modest among

self-sufficient robot. There is critical measure of contrast among hypothetical and down to earth

work cycle estimation of time which can be advanced by embracing diverse strategy.

Furthermore, one could think about an unwinding of the token holding prerequisite in the rush hour

gridlock control plot with the goal that numerous vehicles can leave distinctive at-intersection

zones all the while, and henceforth the presentation of the AGV framework can be improved. After

the model usage, it meets the utilization of AGVs in mechanical fields, stockrooms, clinical fields

and in risky working territories where people can't go.
