THEME : INDUSTRIAL VEHICLE
ROBOT NAME : GRAB N TODDLE
Robot Name: Peacock
This week, we are doing our project with the application of NXT LEGO robots. First, our lecturer asks us to choose a theme and create the robot based on the theme that has been chosen.
Our group have chosen a theme that known as "Zoo" and we will construct a robot that has the shape and functional as animals. So, we decide to start constructing and programming by dividing each task to all of our group members.
The interesting things about this peacock that make us chose to try it are it is believe can dance for every mates that it meets, turns and flutters its tail feathers to other its potential mates. So, we are trying to make our peacock to be function as it is.

Theme : Recycle and Lifting
Robot Name : Evo
This week, we learnt to construct and programme the Lego through our own varies ideas. By doing these, we will understand better the principles of engineering and programming. We also will learn how to design, construct and programme the robots.
Our lecturer has given us a task in order to understand better in the NXT Lego construction and programming. It is the principles of "Recycle" and "Lifting".
The first activity was ‘Recycle' where the robots have to do the same action or the repetition of movement. So, the programmed process is very important in order to do the repetition movement.
The second activity was ‘Lifting' where the robots have the ability to do some jobs such as moving or relocating some object. Our group decides to reinforce the robot accuracy and power in order to do the lifting jobs. Our groups have constructed our robot with the addition of light sensor. It is to sense and lift the object. It has been programmed to sense a ball and relocate the ball to another place.
The design of our robot for the theme of Attacking & Defending was similar to G.O.L.F. design. The reason for chosen this design are because of its stability and arm that it has will be useful to attack the opponents. The stability of this robot came from its lowered structured and three motor used in its construction. We are just modifying the program for this robot to make it suit to the theme.
This robot uses all three motors, two to move it and one to swing its arm. Besides, this robot also used Ultra Sonic Sensor in order to measures distances and detect object in front of it. As it detects the object, it will swing it arm to hit the object and return just like an echo. Based on this application we used it to detect and attack our opponent. Its stability enables "Cool Hitter" to avoid itself from being crumple in its battle.
Heavy and compact design can stand steadily even with extreme force by the opponents. We had measure the weight and our which is one of the lighter designs. We should add any extra accessories to increase the weight even some of them will not be functioning.
towering robot design reduce the stability and prone to collapse if the greater force hit on the lower parts of the structures.
Modify the movement system by attaching gears on tiers help to increase the power to 120% instead of maximum 100%. The speed will decreases but it is not considered as much important because power is much important than speed right now.
Theme : Tug of War
Robot Name: Bumble Bee
It seem simple, unattractive but u won't believe its potential..ahaha..Lets read the story behind it.
This week class session, we are required to produce a robotic based on theme ‘Tug of War'. As considering the theme, we are deciding to build robot based on stability and capability to defend while are being attacking by the opponents.
We had design our robot by using 3 motors, and shape it as a cube to make it more stable. Compare to other team, our robot design is totally different from them. So, we had been laughing by others because our ‘weird' design. They also humiliate our robot. How sad... ~_~
Even though, we are proud with ourselves and we believe that we will prove something for them. As looking for other team, their designs were quite similar to another because their designs are like a mantis and they are using claws to defend themselves and to attack their opponents. They also built their robot as high as possible without considering the stability. So, as they meet their opponent they will collapse and suffering damage. As the result, at the end of every ‘war', they need to repair their robot to meet other opponent. Luckily, we didn't face serious damage and never collapsed in our battle war. So, we win in most of the war..
So, don't judge the book by its cover ...^_^..huhu..lalala... see the video for this week robotic learning session.
At the end of this session, we were realized that to build robot for a theme 'Tug of War' we need to consider a few aspects as:
