The glittering transparent waters of pristine lakes and rivers, lush green fertile slopes and plains, towering peaks, scintillating panorama, and the resulting aura of mystery make this land a beautiful mosaic of all the colours of rainbow. The exotic natural beauty is so captivating and enthralling that it leaves one spell bound. The versatile flora and fauna and rich culture and traditional festivals make the future of this nation really promising. Keeping in line with the spirit of the land, people of the country are lively, energetic and art-loving. The land is cradle to the ancient Indus Valley Civilization. Gandhara art and Buddhism are the most important components of this tradition. The inhabitants of the land are rough and tough with a strong belief in their capabilities and a firm commitment to their purpose of making the nation even greater. The northern areas of the country can rightly boast of being one of the most beautiful places on earth. It is here that the second highest peak of the world K2 commands the admiration and awe from the tourists and locals alike. Here is a wonderful opportunity to observe the rich culture and tradition of the land, particularly during the seasons of fairs and festivals – the dances and songs of the people of the land can easily enliven the dull spirits. Shandur Polo Festival is one of the oldest sporting events that greet fans with its cultural hospitality and excite them with the thrilling moments of Polo matches. Shandur hosts thousands of spectators from inland and abroad on the world’s highest Polo ground each year in the month of July. The backdrop of Hindukush range, hospitality, scenic views, folk dances and some thrilling wild-Polo matches – different from the regular polo – on the world’s highest Polo ground is what makes it a thing apart.
This is Pakistan – Having emerged on 14 August 1947 as an independent state on the world map, the land is full of these spell-bound beauties and infinite opportunities. This green, beautiful and modern capital of the country Islamabad itself is one of the signs of the greatness that future has in store for this nation.
College of Electrical and Mechanical Engineering (EME) Rawalpindi is a constituent college of the National University of Science and Technology or NUST.
Pakistan Navy Engineering College Karachi was another participating team. The team did undergo a lot of preparatory work ahead of the exercise. The team members held preparatory sessions to come up with something original. They used all the three robots – manual, kago, and digital – on the experimental basis. However, the team could not get through in the preliminary competition. The team did undergo a lot of preparatory work ahead of the exercise.

NED University of Science and Technology Karachi was the third participating team. The team members worked meticulously focusing on each and every detail of the robot making process. They did hold experimental demonstrations of all the three robots. Unfortunately in the preliminary competition their scheme could not work properly, so the team could not qualify for the 8th ABU Contest 2009 to be held at Tokyo.
Teams from all the three institutions participated in the contest with positive frames of mind yet in the final show it was EME College Rawalpindi which carried the day. The constituent college i.e. EME offers study and research facilities in the disciplines of Electrical, Mechanical, Computer and Mechatronics Engineering. The laboratories are highly equipped with state of the art tools to help the researchers and engineers carry out research in various fields of engineering. Participating in the first ABU Robot Contest 2002 Tokyo, the college won a special Toyota award.
Ahead of the competition, members of the participating team held marathon sessions and debates and held in-depth study to start working on the project with resourcefulness. Their brainstorming and interactive sessions proved instrumental in enabling them to come up with an original and successful scheme.
This year the theme of the contest is ‘Travel together for the victory drums’. The theme is in fact a game based on an imaginary journey of olden days using this Kago Palanquin. An automatic robot in the front and a manual robot in the rear shall cooperate to carry an automatic Traveller robot in a Kago to the goal with the aim of completing the journey before the other team. Various tasks stand in the way, including a Mountain Pass and Woods. The Kago and Traveller Robot must not be dropped. The Traveller Robot must beat the three Victory Drums when it reaches the Goal Zone. The three traditional Japanese drums are arranged vertically on a platform. The team that beats all three drums first is the winner.
The preparatory work was not easy. The winning team used computer graphics and simulation to get help from. The team has had a series of deliberation and discussion sessions using white boards and other aides. The team members put their heads together to come up with something original and competitive. Each one of them contributed with new ideas. It required close concentration and singular dedication. Besides, ingenuity, the scheme required technical skills on the part of the members to work both as individuals as well as a group. Each one of the members took upon himself a specific assignment related to the main project to accomplish. Basically the team was self reliant in preparing the robot because they designed and made the parts themselves. Before putting the robots in the contest, all the robots – manual, digital and drum-beater/Kago – were properly tested. It was ensured that the automatic robot in the front and a manual robot in the rear cooperate to carry the automatic Traveller robot in a Kago to the goal and to complete the journey quickly. In order to eliminate the margin of error, the scheme was tried again and again. Team members were alive to the fact that in the final competition, the team that beats all three three drums first would be the winner.

I am Syed Ghayur Ahmad, team member and manual operator of Robocon. I’ll operate this robot. In the beginning let me introduce the basic structure. Advantage of using this basic structure is that it is a ‘V’ shape apparatus designed especially to cover mountain passes. Its basic advantage is that when this structural robot will be pushing it from the rear, the front part of the structure would oppose that component and thus force thus applied, thereby making its movement stable and securing it from overturning. It would drive through this chain. You can see we have used chains – four by four. Again its biggest advantage would be that it would facilitate in the process of climbing the mountains. Now let me tell you something about the slider mechanism that we have designed to be placed on the structure. It can be moved in the linear direction; it has a rotator as well, and then again it can be moved in the linear direction. Its advantage is that when the manual robot from the rear would rotate or use its force in opposite direction, then it will automatically adjust itself accordingly.
The slider mechanism was fixed in the machine workshop of the college. It contains three sticks to beat the three respective target drums.

The main brain of our robot is this micro-control board. We have used Pick 18F 4520. In the board, we have 13 ADC Channels, and 2 PWM cc modules which are used for motor drive. Our basic requirement was to take direct input from censors through our Controller/APCs and to manipulate them digitally. Basic reason for scheme is that our game field has multi colours which if manipulated through analogue would be problematic. The digital scheme has given our APCs a great edge. Now we can generate automatic referencing through programming.
Micro-control board that has ADC channels and modules help the motor to drive the machine. It has been designed and prepared by the team members.

I am Robocon’s Team leader. I’ll share with you something about the mechanical structure of the tableau robot. This is our tableau robot with a square base. We have used tyres here which have a tighter grip so that it may keep itself stable on the Kago up to 20 degree and don’t get slipped. We have used high-speed motors in it so that it can complete its task with speed. Besides we have made an extension mechanism that is single activator to beat drum in the height. It implies that we have made and would run the entire extension with a single motor. After its extension, every stick would stop in front of its target drum. We have also set up a rotating mechanism with the structure which will rotate all the three drums with a single push.
The Robots were properly tested ahead of the competition. It was only after repeated trials that the final scheme for participation was approved. In one of the phases of the testing process, it was revealed that the rods on the Kago did not function properly, particularly when it had to pass mountain passes. As a result, its designing and scheme were re-adjusted and improved upon in order to make it work properly. Copyrights @ Amer Rizwan
