- The Lego-Team D created a blue tow truck car made of Lego pieces that can carry other cars. - They also built a yellow car to demonstrate how the tow truck could carry a broken vehicle for repair. - The team divided into two groups, one focused on designing and sorting parts while the other executed the building process in stages, constructing the blue tow truck and yellow car and testing that the tow truck could carry the other vehicle.

2. Introduction
•The main of this product is blue car and it can
carry a car.
•For example, when the car is broken,it can be
carried to the location where you want to
repair the car.
•This car is very strong.If you also have an
accident in the mountains, it will come to
helping for you.

3. List of LEGO parts
Picture-1
These parts are mainly able to make the car body.
Picture-2
These parts will stand to put the car.

4. Blue Car part1
・This photo is part of the production process.
・This unit is base unit of Blue car. So this
unit is very important.
・This is composed of many small parts.
(Yellow , Red , Black...etc)
・Many small parts were used in this distance.
So We were very careful in this distance.
・Work was very difficult.However, it was
completed over time.

5. Blue Car Part2
・Making of part of connection was most difficult.
Making exterior. For example, bumper or window glass and
more.
Flont glass and plumbing of back of seat are unique shape in
any lego parts.
It was difficult unique parts to connection.
・Finish
It looked complete, but we should assemble tire, and put a
passenger.

6. Yellow Car Part1
・We made a foundation that fit the tire.
・Upon failure, the car is not running.
・It is important to yellow and red parts.
It can be run by changing the height.
・There is a foundation for putting the parts
underneath.

7. Yellow Car Part2
・This photo is part of the production process.
・Seals expressed the complex pattern
that can not be expressed in a Lego block.
・Tires are made of rubber rather than made
Lego block.
・Windows are using a transparent Lego
block.

8. Product Prototype
・It is necessary to calculate the limit of
loading capacity.
・It prepares the fixing rope Load, and
requires horsepower and fuel to pull to put
the Load.
・Need to measure the weight of the car.

9. Members collaborate
・Planning (s1200037 Yuma Aoyagi)
I divided my team into two groups.
I decided whether to charge anyone what a quesion.
・Analysis(s1200129 Yuki Suzuki)
I decided that who should be responsible for any of the step.
It was produced or completed in how much time.
・Design(s1170240 Yoshinori Sugihara)
I read politely a manual for we didn’t miss design.
And I sorted many parts to two groups.
・Execution stages(s1210230 Hirokazu Arai , s1200104 Yusuke Saito)
First, We checked blue car has a stage to carry a car and two car has been comleted.
Next, We checked blue car can carry yellow car.

10. CONCLUSION
Construction with Lego was able to more easier to understand construct
than paper blueprint.
We think that every parts had different color is good point. We could
understand parts placement easy.
We can know about prototype.
