1
00:00:00,060 --> 00:00:03,450
So our package was created and the name was awesome.

2
00:00:03,900 --> 00:00:09,000
It's now time to fill in the things required for this course in that package.

3
00:00:09,480 --> 00:00:13,410
The first thing that comes into our mind is obviously the robot.

4
00:00:14,010 --> 00:00:18,780
But before making the robot, we need to understand you idea's creation.

5
00:00:18,990 --> 00:00:23,730
You already have basically means universal robot description format.

6
00:00:24,390 --> 00:00:24,770
Okay.

7
00:00:26,280 --> 00:00:31,470
As the name suggests, it is a universal description of a robot.

8
00:00:31,740 --> 00:00:35,820
It contains certain things, and these three things are interlinked with it.

9
00:00:36,330 --> 00:00:44,910
For example, in our case, we have the base of the vehicles and accosted wheel.

10
00:00:45,330 --> 00:00:52,170
So these are the links of a robot, which I have written first here.

11
00:00:52,830 --> 00:00:57,930
The second thing is how our links are connected with each other.

12
00:00:57,990 --> 00:01:06,090
For example, our wheel left is at this point a right feel as at this point, and Costabile is going

13
00:01:06,090 --> 00:01:07,440
to be at this point.

14
00:01:07,950 --> 00:01:18,360
So this relation of joint this relation of links with each other is known as joint.

15
00:01:18,840 --> 00:01:22,860
Joint is basically an entity which connects to links.

16
00:01:23,280 --> 00:01:23,670
Okay.

17
00:01:24,510 --> 00:01:28,740
And the type of joint can be of many.

18
00:01:29,640 --> 00:01:33,570
The type of joint can be of many available options.

19
00:01:33,960 --> 00:01:43,290
Relations is basically the relations is basically a thing that is connecting both of these things.

20
00:01:43,450 --> 00:01:43,830
Okay.

21
00:01:44,250 --> 00:01:52,350
So we called the basic entities for a you RDF file which contains the robot are basically links and

22
00:01:52,350 --> 00:01:52,800
joints.

23
00:01:53,280 --> 00:01:55,830
So links are actually the physical part.

24
00:01:56,370 --> 00:02:01,560
The joints are actually the relationship between these links.

25
00:02:02,070 --> 00:02:08,850
So what I'm going to do in our robot, the base is going to be at this point and everything is going

26
00:02:08,850 --> 00:02:10,890
to be connected with the base.

27
00:02:11,580 --> 00:02:14,520
That's how we are going to create our robots.

28
00:02:14,730 --> 00:02:15,540
You idea.

29
00:02:15,840 --> 00:02:22,530
But first, let's take a look on a very simple example in which no mesh file or a 3D file is involved.

30
00:02:22,530 --> 00:02:32,220
We are going to first take a look into creating a basic robot with available basic technology, basic

31
00:02:32,610 --> 00:02:35,760
techniques to visualize what we are doing.

32
00:02:35,760 --> 00:02:37,290
How are you idea first?

33
00:02:37,320 --> 00:02:40,680
Let's take a look and then we'll start building our robot.
