1
00:00:00,930 --> 00:00:06,810
This whole journey of this course is all about simulation, but still, we need a robot.

2
00:00:07,020 --> 00:00:10,050
What type of robot and how we are going to do that?

3
00:00:10,170 --> 00:00:13,230
In section number one, we are going to solve this question.

4
00:00:13,890 --> 00:00:21,510
We need to first design the robot as this is the main approach for the course, although you can obtain

5
00:00:21,510 --> 00:00:24,810
any robot in a mesh format from the internet.

6
00:00:25,050 --> 00:00:33,060
No conditions apply to you, but how to solve a problem and to build a robot for that proper solution.

7
00:00:33,330 --> 00:00:37,590
Let's talk about that design thinking for our May solving robot.

8
00:00:37,800 --> 00:00:40,660
The robot is going to be a differential type robot.

9
00:00:40,680 --> 00:00:48,420
I have fixed this condition to is in the simulation and not confuse you with non Holland America and

10
00:00:48,420 --> 00:00:49,440
Holland big stuff.

11
00:00:49,920 --> 00:00:54,000
We are going to be just using a differential type of robot.

12
00:00:54,960 --> 00:00:56,970
What is a differential type robot?

13
00:00:57,660 --> 00:01:05,340
As the name suggests, this type of robot are going to take a turn when they have a difference.

14
00:01:05,700 --> 00:01:09,930
What I mean by that, you can see this robot is facing in this direction.

15
00:01:10,350 --> 00:01:17,850
If its left wheels are going to rotate in the backward direction and the right wheels are going to rotate

16
00:01:17,850 --> 00:01:21,450
in the forward direction, this robot is going to take a turn.

17
00:01:22,560 --> 00:01:27,210
This is what I mean by difference in their rotations.

18
00:01:27,900 --> 00:01:30,390
That's how this robot is going to take a turn.

19
00:01:31,110 --> 00:01:39,060
We change the velocities of one side and stop or reduce or provide negative velocities to the other

20
00:01:39,060 --> 00:01:47,880
side, the side which have less velocity, negative velocity, or slower than the other side.

21
00:01:48,240 --> 00:01:50,490
The robot is going to turn on the slow side.

22
00:01:50,580 --> 00:01:51,960
Okay, that's how it works.

23
00:01:52,350 --> 00:01:56,670
And very slight change in velocity is going to make this robot turn.

24
00:01:56,880 --> 00:01:59,300
No conditions applied similar to the tag.

25
00:01:59,730 --> 00:02:07,320
If this strip starts to move in this direction and this strip starts to move in this direction, robot

26
00:02:07,560 --> 00:02:13,010
of this this tank is going to basically take a turn on this side and vice versa.

27
00:02:13,140 --> 00:02:17,010
If we change the directions of the stripes on the other side.

28
00:02:17,310 --> 00:02:22,950
So we have created a difference in the rotation of the wheel and the robotics are done.

29
00:02:22,950 --> 00:02:24,270
The basic idea behind it.

30
00:02:25,020 --> 00:02:31,740
Now coming to the point of selection, we are going to select the very basic robot and that is going

31
00:02:31,740 --> 00:02:33,840
to be this robot.

32
00:02:34,320 --> 00:02:40,140
Although the shape is not going to be this, the type is going to be this, which is a dolly like robot,

33
00:02:40,530 --> 00:02:45,060
which contains two wheels and a one cluster.

34
00:02:45,690 --> 00:02:52,230
We don't call the cluster to be a wheel because motors are not actually connected to the cluster motor.

35
00:02:52,230 --> 00:02:55,350
They're only connected to these two wheels behind.

36
00:02:55,590 --> 00:03:02,820
So if this right wheel turns in the forward direction, this left will stand in the backward direction.

37
00:03:02,970 --> 00:03:06,990
This robot is going to take a turn towards left and vice versa.

38
00:03:07,950 --> 00:03:08,310
Why?

39
00:03:08,310 --> 00:03:12,480
I have selected this one and not this one, although this one is the same thing.

40
00:03:12,480 --> 00:03:15,900
But there is a slight difference between these two robots.

41
00:03:15,900 --> 00:03:25,260
And that difference is this robot here contains a wheel and this wheels limits the maneuvering for a

42
00:03:25,260 --> 00:03:35,520
robot because this is a this really is only capable of rotating along the z-axis although the ball here,

43
00:03:35,670 --> 00:03:43,380
which we cannot see and I can only see because I have some superpowers now we are going to design the

44
00:03:43,380 --> 00:03:51,420
robot, which is going to have a ball at this point as a casted and upper hand of the ball is it can

45
00:03:51,420 --> 00:04:01,770
rotate in X, Y, Z, all axis, which is very great about the maneuvering as we were only focusing

46
00:04:01,770 --> 00:04:05,190
on a robot that is more agile and more fast.

47
00:04:05,700 --> 00:04:11,520
We were focus as we were just focusing on a robot which is more agile and fast and more maneuvering

48
00:04:11,520 --> 00:04:12,450
performing robot.

49
00:04:12,450 --> 00:04:14,100
So that's our choices.

50
00:04:14,400 --> 00:04:17,880
Let's come to the point of how we are going to design it.

51
00:04:18,600 --> 00:04:24,840
The design process is very artistic and the base design is going to be like this.

52
00:04:27,430 --> 00:04:30,190
He is it is going to be similar to this.

53
00:04:30,580 --> 00:04:36,790
We will be having vigils at this point and exhausted really at this point as it is a simulation.

54
00:04:36,790 --> 00:04:41,440
We don't need to have any sort of electronics and hardware.

55
00:04:41,710 --> 00:04:47,290
We are just going to be creating a body linking things and it is going to be ready.

56
00:04:47,920 --> 00:04:55,960
Now, coming to the point of how we will actually be designing the caster, it is going to be a sphere

57
00:04:56,200 --> 00:05:05,740
which is going to be cut from the metal and it is going to be left with a ball which can rotate in all

58
00:05:05,740 --> 00:05:11,590
possible directions, but we will limited to just the Z-Axis and Y-axis as well.

59
00:05:12,310 --> 00:05:19,330
So one axis is going to be deleted because of the reason we have deleted the half portion, but that

60
00:05:19,330 --> 00:05:20,770
doesn't matter a lot.

61
00:05:21,190 --> 00:05:26,560
So Caster is going to be a half ball and the design is going to be a simple wheel.

62
00:05:28,220 --> 00:05:35,210
Like this, although the circles are totally not perfect and we will design some dreams to give it a

63
00:05:35,210 --> 00:05:37,100
better look as a.

64
00:05:37,730 --> 00:05:40,400
So that is all about a robot.

65
00:05:40,910 --> 00:05:43,690
And obviously it is not going to be a box.

66
00:05:43,700 --> 00:05:51,230
It is going to be a little bit of design, which I will detail you in the design process.

67
00:05:51,230 --> 00:05:58,100
And there are going to be proper dimensions, the length of the robot, the heights, and what are going

68
00:05:58,100 --> 00:06:03,440
to be the proper radius for R v, which is around about 35 millimetres.

69
00:06:03,440 --> 00:06:06,980
And all that discussion is going to be done in the 3D modelling software.

70
00:06:07,430 --> 00:06:09,500
But this is the basic idea.

71
00:06:09,770 --> 00:06:12,890
Let me draw another view of our robot.

72
00:06:12,890 --> 00:06:14,960
So our robot is going to be like this.

73
00:06:16,560 --> 00:06:17,670
And.

74
00:06:19,730 --> 00:06:20,200
Okay.

75
00:06:20,210 --> 00:06:22,550
I think I've drawn a 3D view.

76
00:06:22,760 --> 00:06:25,460
So here we are going to have a vehicle.

77
00:06:25,460 --> 00:06:31,880
This is the front view and these two veal and a cluster beneath the reward.

78
00:06:32,180 --> 00:06:35,600
So this is the front not not the front view.

79
00:06:35,600 --> 00:06:38,540
It is the top view and this is the side view.

80
00:06:39,770 --> 00:06:46,490
And you can see this is going to be what we are going to be dealing with throughout the course.

81
00:06:46,610 --> 00:06:54,020
So let's start designing it in the Fusion 369 any regard to Jakarta is line would be Lamborghini, probably

82
00:06:54,030 --> 00:06:54,380
70.

83
00:06:57,340 --> 00:06:59,530
This process is not that easy.

84
00:07:00,100 --> 00:07:05,590
Obviously, I spent time designing the robot, thinking about how should I design the robot?

85
00:07:05,590 --> 00:07:11,860
And I come with the I came up with a solution that is just design a robot, which is sort of a myth.

86
00:07:12,190 --> 00:07:16,150
That is the main theme of me solving robots in all of the competitions.

87
00:07:16,480 --> 00:07:22,320
So it is sort of a myth, but obviously we need motors to actuate it.

88
00:07:22,330 --> 00:07:28,960
But we limited the number of motors to just two for fast maneuvering, and we're now going to design

89
00:07:28,960 --> 00:07:30,430
it in fusion to 60.

90
00:07:30,430 --> 00:07:31,450
So let's take a look.
