1.1 BACKGROUND:

The military funding of science has had a powerful transformative effect on the

practice and products of scientific research since the early 20th century. Particularly

since World War I, advanced science-based technologies have been viewed as

essential elements of a successful military. World War I is often called "the chemists

war", both for the extensive use of poison gas and the importance of nitrates and

advanced high explosives. World War II marked a massive increase in the military

funding of science, particularly physics. In

addition to the Manhattan Project and the

resulting atomic bomb, British and American

work on radar was widespread and ultimately

highlyinfluential in the course of the war;

radar enabled detection of enemy ships and

aircraft, as well as the radar-based proximity

faze. Mathematical cryptography,

Fig1: 3-D model

meteorology, and rocket science were also central to the war effort, with military-

funded wartime advances having a significant long-term effect on each discipline.

Nepal, country of Himalaya, country of brave armies is still far away from such a

technology thats why we are facing problems in the battle field. So we are planning

to design a device A Robotwhich can be tracked with the GPS system and can be

operated from the remote location. It will be a four wheeled supported with the four

high power motors such that robot will be provided with the obstacle detection

technique using the ultrasound. The robot will be provided with the facilities of voice

control. It will be so powerful that it can be taken to any place where it may be

dangerous to army or we can say a human to be. This whole project will be just a

prototype with the features that can be operated with in a limited range. But it will be

designed in such a way that it can be easily enhanced to make it useful in the real life

with a little bit more investment in the project.

Technology is one of the integral parts to everyone today; use of technology ismaking our life easier and safe. Most of the worlds army and technology are already

become two inseparable parts but still we do not have such scenario in case of our

country. Without the use of technological knowledge and its implementation we cant

feel true freedom anymore, thats why we are focusing on such a project as our major

project. It is true that we are called as the true fighter, brave warrior who never lose

but as time passes scenario of world changes and things changes and the concept of

making the nation safe from its enemy has changed and its all due to advancement in

the technology. So it is the time to rethink and be change according to trend of

worlds changeand it can be only achieved via the use of new advance technology.

So we are trying to play a simple role in achieving all these.

1.2 FEATURES:

Provide with the voice control facilities via RF module. Voice control over the range of more than 500m using the RF signal of VHF

band.

Provided with the 4 wheel drive system, controlled with the 4 different powerfull motors.

Provided with the ultrasound obstacle detection technique on the way. Provided with the wireless camera to transmit the video over the long

distance.

Provide with the GPS tracking device to track and find its location at theremote location.

Provided with the robotic arm to handle different objects. Provided with facilities that it can detect any wireless devices operating

around it.

1.3 SCOPE AND USES:

It can be highly used in the military application as a robotic army It can be used in surveillance of any remote location. It can be used as the security system of any buildings or any places. It can be used to carry weight from one location to another location using RF

1.4 GENERAL METHODOLOGY:

The whole project will be totally based on the research papers and projects which has

already done before. Internet is the main source of information for whole project and

support from our teachers and seniors is the main source of the information to carried

out the whole project successfully.

At first we will study all how the system can be made, material required and at the

same time, availability of such materials in Nepali market will also be studied.

Then we will study and work on the mechanical part and its construction in our

college workshop.

Next step of the project will be the design of the circuits to run the robot or simply to

give life to robot. Then whole circuit will be implemented in the mechanical body we

made to achieve the goals as defined previously in its features.

Finally the robot will be ready to run.

The whole of the above mentioned techniques are used only for the manual operation

of the robot. At first we were quite satisfied with that but then we realized that why

not to make it automatic then we moved to it. So we finally divide our system into

two parts one is manual using the voice command and then the automatic operation.

After having search we come to the point that automatic operation can be

accomplished with the help of GPS and GSM modules. We take this reference form

the project on titled Vehicle Tracking System using GPS and GSM modem it

was a project done already and it was done by the Microtronics Technologies in

this project it is said that the GPS modem will send the coordinate of the location

where robot is to microcontroller then microcontroller will forward its location to

GSM modem then it will forward that coordinate in the form of longitude and latitude

to any remote location from where we can control the given robot.

We are planning to add a robotic arm on robots and it was the project done last year

on titled ROBOTIC ARM WITH WRITING ABILITY we take a reference form

that project to integrate it in our project. It was one of the award winning project of

last year so this project become a great source of information to us to make a robotic

arm.

Our whole project is the collaboration of all the above mentioned projects into a

single project. Whole project will be carried out by considering all above mentioned

points and projects.

second words. This circuit allows the users to choose either the .96 second word

length (40 word vocabulary) or the 1.92 second word length(20 word

vocabulary).The chip has two operational modes: manual mode and CPU mode. The

CPU mode is designed to allow the chip to work under a host computer. Also speech

recognition is classified into two categories, speaker dependent and speaker

independent. Speaker dependent systems are trained by the individual who will be

using the system. Speaker independent is a system trained to respond to a word

regardless of who speaks. There is two step; at first we will train the voice then voice

recognition will be proceed.

3.4 Automatic operation:

In this mode of operation we can use this robot at the remote location which will be

beyond the range of RF. It will be done with the help of GPS system and GSM

module.

In robot tracking project we can track the location of our robot. This project gives

minutes by minutes updates about robot location by sending sms through GSM

modem this sms contains longitude and latitude of the location of the robot.

Microcontroller is the central processing unit CPU of our project.

Microcontroller gets the coordinates from GPS modem and then sends this

information to the user in text sms. GSM modem is used to send this information via

sms.sms will be send to the owner of the robot.

In GPS tracking system the location of the robot is send to remote place and it is done

by the GSM modem. Global positioning system (GPS) modem required minimum 3

satellites to calculate the exact location. These modems communicate only in singleway with microcontroller. This means that it can only transmit data to

microcontroller. GPS modem does not receive any data from microcontroller at the

same time GPS modem does not send data to satellite.

3.5 OBSTACLE DETECTION:

To detect the obstacle coming in the way of robot we are using ultrasound module

having two different ultra sound such that one is used as transmitter and another is

used as the receiver. When obstacle will appeared in front of the given robot them the

receiving one will receive the ultrasound reflected signal and it will come to know

that robot is approaching the obstacle then robot will be stop and returned back and

turn left or right.

This simple approach can be shown in a flowchart as:

EXPECTED RESULT


16/23

16 | P a g e

This robot will be one of the finest robots we have ever had at our college level

projects. It will be provided with all the above mentioned features so that it will be

very helpful for army. The robots will be provided with the help of very fine wireless

camera which can transmit live video over the range more than 500m so that it can be

used in surveillances purpose as well. Other result that we expect are as mentioned

below:

4.1 MANUAL OPERATION:

In case of manual operation, robot will be able to be controlled at the range of more

than 500m using the voice command. As we are transmitting the voice signal using a

microphone which in turn will be passed to ADC and then transmitted via the antenna

of the RF module. The transmitted signal will then be received by the receiving RF

module which will be fixed in robot. Hence, in this way we can achieve all the

manual operation of the robot.

4.2 AUTOMATIC OPERATION:

In case of automatic operation of robot it will sends us its GPS coordinates via GSM

modem to our cell phone then depending upon that coordinate we can locate theposition of the robot with the help of Google map. We are planning to use SIM 510 so

that we can get the correct coordinate of the robot within the 1 minute of the time or

we can say coordinate that is within the range covered by a circle of 1m radius.

As we get the coordinate within the range of circle of 1m radius then we will be

easily able to locate the exact position of the robot with the help of Google map.

4.3 OBSTACLE DETECTION:

As our search, the ultrasound will be able to find any obstacle on its way at a distance

20 cm from it, so that our robots either in case of manual or automatic mode of

operation will never get collide with any obstacle. We will provide the robot with two

ultrasound module so that we can detect any obstacle in its front as well as in its back

so that the robot will not strike any obstacle while moving in the backward direction.

4.4 ROBOTIC ARM:

This robot will be provided with special type of robotic arm so that it will be able to

carry any objects as we specify from our voice command or remote control. It will be

made with the help of stepper motor so it will give very high precision of its

operation.

6.1 CONCLUSION AND DISCUSSION:

This project is mainly imagined, designed and going to be implemented for Nepali

army. But it could be also useful in the field of surveillances, security of any

buildings; it can also be used in mines and so on. It shows that this robot could be a

friend and a savvier when we take security concern into account. It can also used as a

carrier of goods as well.

The main purpose as a student of this project is to learn ROBOTICS and

AUTOMAIONhere in this project we are using voice commend to control the robot

means we are trying to learn audio processing which is a vast emerging field in

electronics and communication. We are using GPS and GSM modem technology to

operate robot in automatic mode means we want to learn about mobile technology

and GPS satellite technology. Through this project even after being a student of

Electronics and Communicationwe are trying to learn the collaborative operation

of mechanical and electronic components.

Up to now its already been a great feeling for us to learn about above mentioned

topics.

6.2 RECOMMENDATION:

This project is a combination of a large number of the different concepts and

technology. So we would like to request our college to support us to complete our

project by proving us with all the required materials we need during our project, only

after that we can complete our task in time.
