Parts of robot :-
- 1 NXT Brick with rechargeable battery pack
- 2 Pairs of large tires with hub
- 2 pairs of large hub
- 3 NXT Interactive Servo motors
- 3 Changeable equipments
NXT Brick with Rechargeable
This robot uses only one NXT Brick with Rechargeable Battery Pack which enough to attach 3 NXT Servo Motors. We decided to use rechargeable battery because it is more efficient, affordable and use less energy. In our minds, if we use more than 1 NXTs, our invention might be bigger in size and face difficulties in movement. Thus, it might not fit to pass through under the bridge.
2 Pairs of large tires with hub
This pairs we used it at the back. We found it more grip and stable if we put it with hub and placed it at the back.
2 Pairs of hub
This types of part we put it at the front part of the robot. We decide to use without tires, robot easily change its direction as friction turn less.
3 Interactive servo motors
Two of the motors we used in the movement of the robot. The remaining motor used for the equipment to move. Sensor, not be used as it makes the robot slower. We prefer programming it based on its rotation, degrees and second.
3 changeable equipment:-
It is very functional equipment. It can complete up to 4 missions
smoothly. It has a huge base area to increase it capacity to take
more loops efficiently.
- LOOPS PICKER
It has long vertical lego design is specialized to take the higher situated loops.
It also has horizontal lego design is specialized to take lower situated loops.

Sekolah Menengah Sains Muzaffar Syah, or formerly known as Sekolah Menengah Sains Melaka, was built on top of a hill with the height of 121.9 metres above sea level. Its area is 12.9 hectare.
Our school consists of 613 students, 356 of them are boys and the rest 275 students are girls. The staffs of our school are around 104 people.
LIST OF WAYS HOW PEOPLE MOVE AROUND THROUGH THE COMMUNITY
- Car & Motorcycle
IDENTIFYING THE PROBLEM
There are several things that made our mode of transportation dangerous. Serious accident that cause death may occur as the movement of transportation is going down the hill. In addition, when a car travels up a hill, it will consume more fuel.
On the other hand, most of the students complain about getting tired going up and down the hill especially during the Friday prayer of the Muslim students. To make things worse, the T-shirt wore by the students during outing will get wet with irritative sweat. Besides, it takes a long time to reach down the hill, about 5 minutes. Based on the research that we make, we found out that we will use more energy by walking. This may cause tiredness or sleepy in class. The calculation of the power (Watt) of a student going up a hill was calculated as shown below:-
Work done, J = mass X g X height of stair X number of stairs
Work done, J = mass X g X height of stair X number of stairs
= 55 X 10 X 0.1 X 273
= 15015 J / 15.015 kJ
Power, W = Work done, J
= 41.7083 Watt
Based on the questionnaire result, we had found out that aero rail transit system is the best solution to fix the problem. This is because, aero rail is a revolutionary high speed transit system with its passenger vehicles suspended below the guide way beam. Aero rail technology is a reconfiguration of tested and proven components currently in service in electric rail transit systems and heavy highway construction.
Aero rail has the benefit of being constructed in air space over existing publicly owned right-of-way. This benefit not only greatly reduces or eliminates the need to acquire costly right-of-way, but often reduces or eliminates the need for Environmental Impact Studies.
Aero rail uses steel wheels on steel rails to improve speed, eliminate "tire sing," and to use COTS (Commercial Off-The-Shelf) technology so important in holding down transit system costs. To reduce vibration, these wheels have an electrometric component between the hub and steel tire.
So what will it take to make this solution happen?
The school will acquire a large sum of money for the construction of the aero rail transit system from the top of the hill, going down the hill. The government via the Ministry of Education could help in providing the money.
With the existence of such a high-speed transit system, of course it will be easier for the students to move up and down the hill, no more tiredness. The teachers and the other school staffs may as well use the aero rail, which will benefit them in term of reducing the expenditure on petrol. They can park their cars downhill and go uphill via the aero rail. This will also decrease the percentage of air pollution. In this case, the construction of aero rail in the school area will also help in maintaining the quality of the environment.
Movement will become more comfortable, easier and indeed, safer. A student has only to wait for his turn to go inside the cozy aero rail compartment, either from downhill to uphill or the opposite direction. Students’ energy usage could be reduced and no sweating. In addition, students can avoid injuries as the result of falling down the stairs.
We share with our community by;
- Pass out brochures/flyers

Each and every day, transportation touches your lives. Your team travels to the places where they learn, to the places where they play, to visit friends and family. Things we want, clothes we wear, the food we eat, the water we drink, medicines we need - all these travel over highways, on paths and trails, along railroad tracks, up and down rivers, across oceans, over mountains and deserts, along the streets we live on. Information travels to us from experts, teachers, friends, and family. It comes to us by word-of-mouth, over the phone, in books, from websites, in text messages.
Now, consider. A potato chip can travel through a factory - flying from machine-to-machine without being broken - but more than 50,000 kids who traveled on skateboards had to be taken to the hospital. Is all this travel as safe as it could be? Millions of people (and the things they need) get stuck in transit every day. Is all this travel as efficient as it could be?
Your challenge this season is to look at your community and discover how people, animal, information, and things travel. Once you know how people and things move in your community, pick one main mode of transportation and do some research. What kinds of problems keep people and things from getting where they are going safely? What kind of problems keep people and things from moving efficently, getting where they are going quickly and using the least amount of energy? How could your team help solve one of those problems?
IDENTIFY A PROBLEM
Begin your project by describing your community. This season, it is up to your team to define your community. Is it your school? Your neighbourhood? Your city, village, or town? Your country? The world? Be prepared to share how you defined the community.
Next, create a list of the ways that people, animals, information and things move in, around, to and through your community. Be creative. Be silly. Be serious. Thinks about everything that gets moved, including yourselves!
Once your list is complete, pick one way that people and things move in your community and learn more about it!
Whether your team chooses planes, boats, trains, cars, trucks, skateboards, rollerblades, bicycles, donkeys, llamas, camels, your feet...it's time to research. What makes your mode of transportation dangerous? What prevents people, information, animals, and things from getting where they need to go? What makes them take longer? What makes them burn more fuel? Search out the problems. Look at reports. Read books. Browse websites. Conduct a survey. Check with experts who work in and around your community. Use any research tools you have available. Be prepared to share your information sources.
CREATE AN INNOVATIVE SOLUTION
Choose one of the problems and suggest a solution. What can be done to fix the problem? What will it take to make our team's solution happen? How will your solution help your community? How can your team make moving from one place to another safer and easier? A great solution might take all the imagination and ingenuity your team can muster. It might seem so obvious that you wonder why the problem even exist. And remember, the most important thing is to have fun while you make a Smart Move.
SHARE WITH YOUR COMMUNITY
Now, tell your community about the problem you researched, and how your solution can help. You choose how to share what you've learned. Give a talk for parents. Create a website. Perform a skit. Make a comic book. Rap. Create a poster. Pass out flyers. Write a poem, song, or story. Present your research and solution to lawmakers.
Your presentation to the judges can be simple or elaborate, serious or designed to make people laugh while they learn-but to be eligible for project awards at tournament, it must:
- Describe your community, the problem, and your team's solution
- Show that your team did the research and tell about your information sources
- Be shared with someone outside of your team
