00:00:00,000 --> 00:00:10,000
This is the design of the project that we are going to build in this course.

1
00:00:10,000 --> 00:00:22,000
It is a very classic project for second official because in it you can mix some mechanism and some structures

2
00:00:22,000 --> 00:00:39,000
and then before or next we can add an engine and we can add an Arduino board and we can create a project different or we can extend the project.

3
00:00:39,000 --> 00:00:53,000
But in this case this is the first idea because then when we study 3D printing in the next unit,

4
00:00:53,000 --> 00:01:01,000
we are going to repeat this project but just using the 3D printer.

5
00:01:01,000 --> 00:01:06,000
So it's complicated, this is going to be the first part of the project.

6
00:01:11,000 --> 00:01:24,000
In any design we have different documents. First of all we have the memory, then the planning with a list of materials and tools,

7
00:01:24,000 --> 00:01:31,000
a budget and the most important at the beginning which is the sketches and the parts.

8
00:01:36,000 --> 00:01:41,000
We are going to do a wheel. Everybody knows what is a wheel.

9
00:01:41,000 --> 00:01:54,000
So indeed it consists in two parts that join with small sticks and holding from the sticks we have some swings

10
00:01:54,000 --> 00:02:04,000
and all the other things are supporting with something that can be the structure stable.

11
00:02:04,000 --> 00:02:15,000
So we need very probably also something that we are going to use as base, that it is not included in the project,

12
00:02:15,000 --> 00:02:25,000
but obviously as a logic thing we must add it at the end in order to increase the stability of the structure.

13
00:02:26,000 --> 00:02:41,000
As always, we must mark all the parts of the project, then hone and cut them with different materials.

14
00:02:41,000 --> 00:02:56,000
We are going to mix and combine some materials as a foam board that is usually used in different technological work

15
00:02:56,000 --> 00:03:12,000
with plywood that I think maybe you have already used in the past course and cardboard mainly to create the swings.

16
00:03:14,000 --> 00:03:23,000
When we have marked the different parts with the ruler and the pencil, we must hone and cut them.

17
00:03:23,000 --> 00:03:34,000
Obviously, the foam board with a cutter, the plywood with a saw and the cardboard with a scissor.

18
00:03:34,000 --> 00:03:46,000
Then we need to do some drills and holes using drills and it is also important because for example for the foam board

19
00:03:46,000 --> 00:03:52,000
we usually use an awl or something similar because sometimes it can be dangerous.

20
00:03:52,000 --> 00:03:56,000
And for the plywood obviously drills.

21
00:03:57,000 --> 00:04:03,000
We must adjust using some paper and files and finally we must join.

22
00:04:03,000 --> 00:04:16,000
The way we must join it depends, but from my point of view we must join first of all the two parts of the wheels with small sticks

23
00:04:16,000 --> 00:04:25,000
and then when we have joined this, we must join the axis of the wheel.

24
00:04:25,000 --> 00:04:37,000
Finally, the own part with the two parts of the wheels and the axis must be joined to the support

25
00:04:37,000 --> 00:04:41,000
and obviously the support to the base that is in the project.

26
00:04:42,000 --> 00:04:46,000
Finally, you can hold the swings.

27
00:04:46,000 --> 00:04:59,000
To do the swings we can use cardboard and just blend in and paste with glue this one.

28
00:04:59,000 --> 00:05:09,000
So maybe using wires you can hold the small swings to the wheel and that's all.

29
00:05:09,000 --> 00:05:13,000
Finally, you can paint and so on.

30
00:05:18,000 --> 00:05:26,000
Materials and tools that we have already told you.

31
00:05:28,000 --> 00:05:31,000
I think everybody knows everything.

32
00:05:32,000 --> 00:05:43,000
This is the part more or less because indeed I don't know exactly the prices of the materials

33
00:05:43,000 --> 00:05:50,000
but I think it's a good idea if I included the work force and the tool wear.

34
00:05:50,000 --> 00:05:57,000
Taking into consideration you are five in the group it's not so expensive

35
00:05:57,000 --> 00:06:07,000
because taking into consideration that two euros is about for the wear of the tools and the work force.

36
00:06:08,000 --> 00:06:21,000
This is the part more or less, indeed it has just only three categories of parts

37
00:06:21,000 --> 00:06:29,000
the wheel, the supports and the swing.

38
00:06:30,000 --> 00:06:38,000
I hope with this planning and with this design you can create a good wheel.

39
00:06:38,000 --> 00:06:44,000
Obviously, what you must do is your own design, it's just only one example.
