A Little Must to Say

That thing in your hands now, is a witness of the

great effort, huge passion and strong belief of all

out there with the name CORDian.

The CORD is a thank you letter and dedicated to

everyone who participated one way or another to

help the Competition Of Robot Design to rise up

and change for the better.

For all CORDian members out there in all COR-

Dian branches, thank you all for being you. And

Special thanks to all our sponsors, those who hel-

ped us construct or broadcasted what we constru-

cted to the public.

Towards Egyptian and Arabian Advancement...,

Chairman word

Many people quit because they think they cant,

some people believe they can but, few take the

initiative convinced that they can help others

believe they can

The idea of CORD was born many years after it

became feasible, and took more time before it

became to reality but, the reason it became

feasible is the belief in change and the reason it

came to reality is the Hard-Teamwork.

I take my vow today that CORD will reach

further and higher than anyone ever imagined

because there are people out there, some known

and some arent, who believes in it and we cant

let them down.

Our Journey:

The Egyptian and Arabian societies are very

traditional people that need time and patience to get

used to a new idea, and the robots was that new idea

we wanted to implant. If we look at the progress of the

robots culture everywhere, we find it as an evergrowing interest yet, in Egypt and the Middle East,

robots are only linked to western movies as a myth that

we can never achieve.

The first official appearance of CORD was year2007 in

the faculty of engineering, Ain Shams University

campus with a poorly funded booth which was made

from a disk and little decorations that were made from

scratch, among those decorations stood a little robot

made from house garbage. That disk with that robot on

it started a new concept suggesting that we do can

build a small robot also we can do it from nothing and

we just have to use our minds and beli-eve that we can

do a change to make a difference.


8/40

That first disk along with the robot was able to

convince 50 teams to participate; we also offered them

three open sessions sharing with them all the

information we had, at the day, about building robots.

Not all of the participants came to the sessions but, in

the competition day we stood proudly among 15 teams

that managed to build their own robots for the first

time. Only one robot was effective and capable of doing

the task and the others did try but, it was all good for a

start and that was where we learned that this idea will

have a future, little did we know back then that the

future we were looking for was much bigger.

The many events that followed the August 2007 weremuch more successful and more inspiring telling there

is more. Number of participants increased hysterically

event after the other as we were forced to grow more

and push our skills to the limit.


9/40

After having one competition at an event, it became

five. And after having fifty teams as a start, we had

three hundred growing to one thousand teams, year

2009, with an average of 3 persons per team. At last we

had two main branches instead of one; one in Cairo and

the other in Alexandria; new market eager for

technology and for anything new, plus the robot

academy in Cairo which can be considered as the next

step towards more technologically advanced robots.

Having emotionally touched too many participants and

their relatives, we also made a strategy of having the

competitions in big clubs so, more and more people will

learn about our work and what we are trying to do.With all that, we managed to put the foundations to our

market in the people's minds and made sure that with

further work we will be having more and more

exposure to people minds and that wining their trust

wont be such a big problem.


10/40

In order to secure what was achieved and move on to

achieve more, CORD is using its good reputation and

high public relation previous achievements as a solid

base. CORD is becoming well known through both

universities and even schools, and that achievement is

strengthened by the trust of the participants' parents

and how much they encourage their sons and daughters

to join, they even come to support them in the

competition days.

All of that added to the ease of starting new branches

for CORD all over Egypt with new chance to go

international. CORDs achievement from the love and

encouragement is undeniable. Any achievement thatCORD had is dedicated to the Egyptian society.


11/40

Our Activities:

We believe that we are in an ever growing business

that has no limits and as the time goes on new thing

should be discovered and either we will have a hand in

discovering them or we will have a hand in sharing and

teaching them to all interested. But, so far, this is whatwe offer which varies in all our branches:

1. Beginners level robotic competition

2. Advance Mechanical robotic competition

3. Advanced interacting robotic competition

4. Wireless robot fight competition

5. Robot building open sessions

6. The Robo-Academy

7. The One Week/Day CORD

And we will briefly discuss some of them in coming few

pages.


12/40

The Robo-Academy is a part of the legend called

CORD, it started in 2008, in the second year of the

launching of CORD. It consisted of only two workshops

both having the same core, General Robot Building

Techniques, however, the next year witnessed a very

large expansion where the number of workshops was

doubled and their cores varied so they completed each

other.

The first real Robo-Academy competition was of the

year 2009 called; Operation: E.S.C.A.P.E.

The four workshops of the Academy were formed into

mixed teams so that, a team will have a mix of the four

knowledge.

The scenario of the competition was an imaginary

situation of an imprisoned spy escaping from an enemy

jail and passing through many maze like routes ending

at a steep hill that he will have to overcome.


13/40

After crossing the hill, the spy had to hit a big drum to

locate himself to his allies to come get him.

The maze consisted of an open turning route

surrounded by walls of 40 cm high and the route was

divided into three check points each after a dead end in

the maze.


14/40

The hill is located at the end of the maze. The

inclination is a slope that climbs a distance of 1m by 15

degrees with the horizontal plan.

The entrance of the hill is considered as the 4th check

point there is.


15/40

The drum is elevated from the slope tile by 25cm

perpendicular with the slopes plan and is located

within the walls of the slope.

The robot had a chance of getting fixed or transform-ed

by its user before it starts the slope at which it will hit

the drum at the very end.


16/40

The robot should move automatically once the round

started using either of the two methods; Obstacle

avoiding and line tracking and both was illustrated in

the academy before the practical experience came to

bolden the ideas in minds by applying.

The obstacle avoiding method was used relying on thewalls while the line tracking was used due to the given

of white line in a black area that can be detected and

used for certain and accurate guidance.


17/40

While the climbing up the slope, the control of the robot

is transformed to wireless control instead of automatic

control where a team member is asked to adjust the

robot at a suitable distance from which he will control

the arm of the robot to hit the drum once declaring the

end of the round

Mission Accomplished


18/40

The robot weight should have not exceeded 4kg. The

maximum approved voltage was 12 volts. The rules and

constrains of the competition was a true long step

towards a more advance generation of robots and

participant learned that gradually in a workshop

environment.

The experience gained from that event was extremely

important as it helped participants overcome many

obstacles. They learned to trust their knowledge and

creativity, they learned how to work in group with

teamwork, they learned to take decisions and choose

from alternative design, they learned to work with their

hands and they learned all that in a stressful yetinteresting environment with challenges yet with full

technical support.


19/40

The one day Competition of Robot Design has

many benefits for its participants that, its perfect

teamwork training, excellent creativity training and

measure and finally a must have technical experience

helping minds figuring out simple physics. It implants

the concept of challenging the circumstances and using

whatever available under spot providing its

participants with both stress management abilities and

ambitious attitude.

The day simply consists of four main stages; in the

beginning CORDs instructor break the ice with the

audiences providing them with the agenda of the day

and what they need to know about CORD and itsactivities and what benefits they will acquire. The

second stage being the most important is the

transmission of the knowledge of simple robotic

mechanisms to audiences in a way that is guaranteed to

be easy and exciting.


20/40

The day is held in a workshop environment so;

participants are interacting with the instructor and the

organizers to get the maximum practical knowledge.

The third stage is the actual practical experience with

participants divided into teams trying to use only the

available materials and their acquired knowledge to

build their robots. The robots are built for a certain task

specified for the participants with examples, simple

charts and scenarios. The final stage is the competition

itself and the announcement of results plus the prizes

for winning teams.

The One Day CORD contests are very flexible and

available for different ages and cultures. The event isone of the most effective promotional tools of CORD and

is guaranteed to have the expected great impression on

the audiences and the sponsoring entities as it did

before in previous experiences.


21/40

Our Success:

In just one year, CORD has managed to achieve an

unpredictable exposure. CORD appeared in all the

means of advertising, online, seen, read and heard. Mr.

Ibraheem Hegazi's article about CORD in Al-Ahram

newspaper was a turning point. No words could thankthis man on his support which resulted in solving the

fund problem that CORD had. Also resulted in the

appearing of CORD on the papers of AlAhram in two

Friday issues in Mr. Ibraheem's Article and appearing

on Modern Sport's screen in the famous talk show

presented by Mr. Ibraheem himself AlReyada we

Alnas.

Back in CORD07, someone else gave CORD a good

support who was the actor Hussien Fahmi on his show

Alnas wa Ana. Also in the same year, the opening of

CORD was filmed and broad casted on Nile News TV in

its formal news which led to the exposure of CORD five

times on Friday.


22/40

Entering a new kind of media the read one, CORD

managed to appear on the second page in Akhbar

Alyoum news paper in article about the achievements of

the Faculty of Engineering, Ain Shams University. In

order to address different kinds of audiences, CORD

also had the chance to appear in the Rose AlYoussef

newspaper.

All of the previous public relation achievements were by

nothing but the belief in the idea from respectable

figures in the Egyptian society but, other achievements

was made by the CORDian crew to sustain their success

by media sponsors. Invading the heard type of media,

CORD was able to broadcast in one of the most famousprograms on Cairo's no.1 radio station Nugoom FM.

Continuing with non-governmental entities, CORD

appeared in the popular youth program Shababeek on

the Dream TV screen with sponsorship deal.


23/40

All of the above was great but CORD's big hit was our

two related deals with both Universal net and Good

News. CORD managed to convince Universal net to

participate in CORD as a main sponsor in exchange of

a 1min 39sec fully 3D animated movie to be projected

on Good News cinema house's screens. Fifty shots were

successfully screened in Porto Marina, Dandy Mall and

Grand Hayat screens.

Most of the previous exposures targeted no specific

market but, to be more focused on the engineering field,

CORD appeared two times on the Alam Rakami

newspaper published by the ministry of communication.

Engineering segment was focused on for two mainreasons: first is that CORD aims to teach future

engineers some of the hard skills needed in job market

that they have to work with their hands and apply what

they learn to build a robot. The second reason is that

most of the CORDian crew needs to be from the

engineering field having special skills to guarantee the

sustainability of CORD.


24/40

Moving on from the exposure and media achievements

to the previous activities done by CORD. CORD's

achievements in this section are due to the fact of how

much the Egyptian youth can be initiative if given the

chance. A problem with the Egyptian society that they

lack taking the first step, CORD knew the characteris-

tics of the society so well that it knew that we have to

approach everyone we can or else, they won't hear about

us, as they lack taking the first step, but, once they see a

dream they can be like a flame lighting the dark road,

as they are initiative if given the chance.

Alexandria as a very beautiful city of Egypt that goes

under a lot of development, selecting itself as the secondexpansion of CORD. CORD was the first intruder of the

student community in Alexandria that ensured them

with bold evidence that students can also build their

community and that they have to give as much as they

take. Being the first student activity in the faculty of

engineering, Alexandria Univ., we also had to spread

the organizational concept.

Robot Building info:

In this section we are trying to focus on the main info

that we provide participants with in the open sessions.

You will find in the coming few pages the simple

wording and pictures of building a small wired-remote

controlled robot of the beginners level as just a start toget you going.

Enjoy,

Rules:

1- Any movement is a resultant of forces

2- A plan is determined with 3 points

3- Vs. v

Simply is that when a diameter of wheel is elongatedthe speed it provides increases when given the same

RPM at its center.

4- acceleration Vs. speed

Lately it was declared in civil engineering that what we

are concerned more is the acceleration of a movement

and no t the movement itself so; if you dont have controlover the speed, which is mostly the case in a beginners

robot, just use lower speeds and masses to reduce the

effect of inertia from acceleration.

5- Friction co-efficient types (stat., dyn. & rolling)


27/40

The highest recorded

speed of a Maglev train is

581Km/h. and the energy

consumed is generally to

overcome air drag.

Humanoid robot created

by Honda. Standing at 130

centimeters and weighing

54 kilograms.

As of February 2009,

there are over 100ASIMO units in existence.

Each one costs under $1

million & some units are

available to be hired out

for $166,000

A skid steer is a vehicle maneuvered by skid

steering, a method of steering through braking orengaging tracks or wheels on one side of a vehicle.

The skid steering vehicle is turned by generating

differential velocity at the opposite sides of the

vehicle, as the wheels or tracks are non-steerable

(fixed position).


29/40

So; the easiest way to move a vehicle in such a small

scale is the skid-steering using low speed drives. Put in

mind though that there is no guaranteed way toconstruct a gear box in home so, you either buy to

different gearboxes with their drives attached or you

extract them from a dying toy.

Simply you attach the two gearboxes to any opposing

sides in your vehicle and you connect the drives with

reversing polarity switch & a battery..and youre done


30/40

The pictures is worth a

thousand word, all that

you have to do is to take

two injectors and connect

them with a hose and you

can then transmit the

action of your finger

almost to any where

depending on the length of

the hose.

Simple Hydraulics

Simply Scientific:

Why accepting some errors in a material in favour of having a

specific property needed, when we can get the property and its

opposite at the same time? That is considered the concept for

using composite materials. The discovery of the composing

concept is not the bang itself while what is considered most is

the output of the composition but, what are composites anyway?

Composite materials (or composites for short) are engineered

materials made from two or more constituent materials with

significantly different physical or chemical properties which

remain separate and distinct on a macroscopic level within the

finished structure. The composing doesnt involve any chemical

reactions and it will be clear from the coming examples that

composites play a great role in our lives.

Starting with nearly the most recent discovery in composites

now which is GLARE. GLARE is a "GLAss-REinforced" Fiber

Metal Laminate (FML), composed of several very thin layers of

metal (usually aluminum) interspersed with layers of glass-

fiber, bonded together with a matrix such as epoxy. The uni-

directional layers may be aligned in different directions to suit

the predicted stress conditions.


32/40

Although GLARE is a composite material, its material

properties and fabrication are very similar to bulk aluminum

metal sheets. It has far less in common with composite

structures when it comes to design, manufacture, inspection or

maintenance. GLARE parts are constructed and repaired using

mostly conventional metal material techniques.

GLARE is currently (2004) the most successful FML, patentedby Akzo Nobel in 1987 and now entering commercial

application on the Airbus A380, which has recently received a

full type certificate from the FAA and European Aviation

Authorities. The patent cites as inventors Roebroeks and

Vogelesang, two former professors at the aerospace engineering

faculty of Delft University of Technology, where much of the

R&D for GLARE was done in the 1970s and 1980s. Later,

NASA interest in reinforcing metal parts with compositematerials as part of the Space Shuttle program led to the

introduction of fibers to the bond layers, and the concept of

Fiber Metal Laminates was born.

GLARE when proposed to serve as the main skin of the worlds

biggest commercial airliner Airbus A-380, it was for nothing

but its competing weight verses aluminum. Before the A-380 all

airliners were mostly made from aluminum as the skin andTitanium as the skeleton.

In a simple experiment, a dead chicken is fitted in a pneumatic

gun and projected in a certain speed to replay the action of a

projectile hitting the plane during its flight. At first usual

aluminum skin was subjected to the projected chicken and the

results came in a success for the aluminum but, in aviation

world, in order to go large you need to go light. A less thickness

aluminum sheet was then tested and was severely ripped apart.

A new GLARE sample simply aluminum sheet and woven

glass fibers was then in the spot and it only bent a little.

Using GLARE reduced the whole weight of the A-380 by 25%

and the concept is easy. The aluminum gave the structure the

flexibility needed while the glass-fiber was responsible for

providing the strength and not allowing the thin aluminum

being ripped. Also GLARE passed the explosive test of the

European aviation authorities.

Currently Glare is being produced for the Airbus A380 at Stork

Fokker in the Netherlands. Stork Fokker has opened a brand

new facility next to its existing facilities in Papendrecht the

Netherlands. There Stork Fokker is able to produce Glare sheets

of 4.5 m x 11.5 m including the milling of doors windows etc. on

a state-of-the-art 5 axis milling machine with a movable bed.

Looking back in time, Jankeas Khan with his dream on ruling

the world had the same problem. He needed a mobile bow for his

men to lunch arrows while horse mounted and the conventional

long bow back then didnt serve the task while shortening the

bow cause it to be fractured. The solution was reinforcing the

wood with a front layer of deer muscles to be subjected to tension

while the inner of the bow was fortified with buffaloes horns

that took compression.

Throughout history man was able to use his surrounding to

serve his needs, and using composites is just another prove of

mans capability of making a change and making use of his

great gift from his creator, his mind. In the incredible human

machine man we find that a great composite exists which is

bones. Simplifying the concept, bones are made from very

different materials that can be represented in Glass and

rubber. Image yourself with a rubber skeleton and the re-

imagine in the glass form. The combination of .both is

what keeps you moving through life.

Entertainment trivia:

What could happen if the Soviet Union didnt fall?... Sierra is

answering that question in its new strategy game World In

Conflict. The creators of the game is pretending that cold war

between USA and USSR didnt end with the soviet Union

dissolution but, with a hot war that is WWIII .

From 1945 until its dissolution in 1991, a period known as the

Cold War, the Soviet Union and the United States of America

were the two world superpowers that dominated the global

agenda of economic policy, foreign affairs, military operations,

cultural exchange, scientific advancements including the

pioneering of space exploration, and sports.

The games main Armies are The NATO (North Atlantic Tre-aty

Organization), USSR (Union of Soviet Socialist Republi-cs) and

USA (United States of America). The NATO is simply an

organization established as a system of collective defense

whereby its member states agree to mutual defense in resp-onse

to an attack by any external party.

Creativity Tips:

- Curiosity

- Challenging

- Constructive discontent

- Problems can be solved

- Accept judgment and criticism

- Seeing the good when its all going bad

- Problems leads to improvements

- Problem can be a solution

These nine above statements are known as the nine

creative attitudes. If stop for a second and made a little

judgment of your own life instead of judging others, you

immediately realize the importance of having and

dealing with these attitudes with eve-ryday problems.

Imagine your life when its all about positivity

A Quote with a story:

You may recall Eli Whitney's story of watching a cat

pull feathers through a cage -- it was how he thought of

the invention now known as the cotton gin.

A less well-known story involves Catherine Ryan, who

invented locking nuts to hold bolts in place. Her

inspiration was how her own wedding ring kept getting

stuck on her finger. She saw that if something in the nut

could expand after a bolt was placed inside a nut, it

would hold the two together.

Other inventions come about when their inventors try to

think of uses for things - vulcanized (heated) rubber fortires came about that way. Have you heard of "yellow

stickies They were the result of a "failed" adhesive

experiment which was too weak to market, until the

chemist figured out that a weak adhesive had good uses

too.

You can never solve a problem on the level on which it

was created. ALBERT EINSTEIN
