WEBVTT 00:00.140 --> 00:06.500 Once you have a machine with ubuntu 24, we can proceed with the installation of Ros2. 00:06.890 --> 00:13.370 During this course, you can decide which version of Ros2 to use depending on the ubuntu version that 00:13.370 --> 00:14.390 you have installed. 00:14.420 --> 00:21.530 If you are using ubuntu 22, then you will need to install the version number of Ros2. 00:21.560 --> 00:28.670 Otherwise, if you are using ubuntu 24 like in this case, you will need to install Ros2. 00:28.700 --> 00:29.240 Jazzy. 00:29.720 --> 00:36.980 The code that you are going to develop during this course is compatible with both of these Ros2 versions. 00:37.010 --> 00:44.630 In this lesson, as I am on ubuntu 24, I am going to install the version jazzy of Ros2 and you can 00:44.630 --> 00:47.660 find all the commands that I'm going to use in this lesson. 00:47.660 --> 00:51.230 Also in the resources of this lesson as a PDF. 00:51.530 --> 00:58.640 To start the installation process, let's open here the Ros2 jazzy installation page. 00:58.640 --> 01:04.960 So actually this one here that you can simply find also in the resources of this lesson. 01:04.960 --> 01:09.220 And now we can simply copy paste all of these commands here. 01:09.220 --> 01:12.790 So all of these commands that you can find here. 01:12.790 --> 01:15.010 So let's open a new terminal. 01:15.130 --> 01:17.080 Let's put this one on one side. 01:17.080 --> 01:19.270 And let's start with the first one. 01:19.270 --> 01:24.310 So actually this one is only used in order to check the current local. 01:24.310 --> 01:26.380 So we can avoid using it. 01:26.380 --> 01:29.740 And we can start with the second command. 01:29.740 --> 01:31.690 So let's press enter. 01:34.660 --> 01:37.720 And we need to do the same for all the other commands. 01:37.720 --> 01:41.500 So let's take also this one and let's paste it. 01:42.100 --> 01:45.220 Let's take this one here as well. 01:46.210 --> 01:50.800 And finally let's also take this one here. 01:50.800 --> 01:51.430 Perfect. 01:51.430 --> 01:54.520 So with this one we have set the local. 01:54.550 --> 01:57.910 Now let's move on to the next chapter. 01:57.910 --> 02:00.670 So the enable required repositories. 02:00.670 --> 02:05.160 So let's start by copying the first command and let's paste it. 02:05.610 --> 02:07.320 The second command. 02:08.190 --> 02:08.970 Perfect. 02:09.000 --> 02:10.650 Let's press enter as well. 02:12.600 --> 02:15.060 Now we need to install this package here. 02:15.240 --> 02:17.340 So we need to update the system. 02:17.340 --> 02:19.470 And we need to install curl. 02:19.560 --> 02:22.140 And we're going to use this package here. 02:22.140 --> 02:22.890 So car. 02:22.980 --> 02:26.490 In order to download this key here. 02:26.520 --> 02:27.840 So let's paste it. 02:27.840 --> 02:28.710 Perfect. 02:28.740 --> 02:32.430 Now we can also copy this command here. 02:33.120 --> 02:35.250 And let's paste in our terminal. 02:35.280 --> 02:39.030 And now finally we are to the real installation part. 02:39.030 --> 02:41.460 So let's start by installing this one here. 02:41.460 --> 02:46.110 So the Ros developer tools that we are going to use in this course. 02:46.110 --> 02:49.080 So let's take the Ros developer tools. 02:52.380 --> 02:54.420 Let's type the Y. 03:02.600 --> 03:08.840 And now once we have the Ros developer tools, we can move on to the actual installation of all the 03:08.840 --> 03:10.040 Ros two components. 03:10.040 --> 03:16.730 So first let's update our system and let's also upgrade it. 03:19.130 --> 03:19.850 Perfect. 03:19.850 --> 03:25.430 And then we can finally install here the Ros Jazzy desktop version. 03:25.430 --> 03:31.790 So this one here that as you can see here is the recommended one as it already includes some visualization 03:31.790 --> 03:33.950 tools like for example RVs. 03:33.950 --> 03:39.470 It also contains demos, tutorials and as you will see, a lot of useful packages. 03:39.530 --> 03:42.560 So let's copy and let's paste it here. 03:42.560 --> 03:46.310 So let's type again the letter y and let's press enter. 03:46.340 --> 03:53.480 Now this command is going to take a while as our system now is downloading almost 1.5GB of data. 03:53.480 --> 03:56.420 So let's wait for the installation of Ros to. 04:06.990 --> 04:11.610 Once the installation of Ros2 is finished, we can move on to the final part. 04:11.640 --> 04:15.030 So this one here, that is the setup of the environment. 04:15.030 --> 04:18.480 So actually we need to insert this line here. 04:18.510 --> 04:22.200 That is the source of the Jessie installation. 04:22.200 --> 04:26.250 So of the Ros2 Jessie version that we have installed on our system. 04:26.250 --> 04:27.810 And we need to insert this one. 04:27.810 --> 04:32.610 So we need to insert this line here within our bash RC file. 04:32.610 --> 04:34.860 So if you can see here. 04:36.990 --> 04:40.260 There is a bash RC file. 04:40.260 --> 04:45.390 So this one here that is automatically available in your home folder. 04:45.390 --> 04:48.690 And so now we can modify this file here. 04:48.720 --> 04:55.830 And for example we can use nano to access the bashrc file. 04:55.830 --> 04:57.330 So let's modify this file. 04:57.330 --> 05:01.950 And actually we need to go at the end of this file here. 05:01.950 --> 05:05.000 And we simply need to paste this command here. 05:05.000 --> 05:06.710 So the source of the. 05:06.740 --> 05:08.720 Ros chassis installation. 05:08.720 --> 05:12.380 Now let's press Ctrl O to write the file. 05:12.380 --> 05:13.850 So let's press enter. 05:13.850 --> 05:16.130 So now we have saved this file. 05:16.130 --> 05:19.010 And with Ctrl X we can exit. 05:19.010 --> 05:19.760 Perfect. 05:19.760 --> 05:26.390 So now that we have sourced our Ros jazz installation, if we open a new terminal we already can use 05:26.390 --> 05:28.520 the command Ros two. 05:28.790 --> 05:33.560 And so for example let's use for this very short demo the command L. 05:33.560 --> 05:34.970 So let's press enter. 05:34.970 --> 05:40.670 And actually this command just confirms us that ros2 is properly installed in our system. 05:40.670 --> 05:43.910 So actually we can see that we have no errors. 05:43.910 --> 05:51.470 And actually here the Ros to ALP command provided us with a very long list of all the commands that 05:51.470 --> 05:53.570 we can use with their description. 05:53.570 --> 05:59.210 And don't worry if you don't know this command yet, or if you don't understand what they are used for, 05:59.210 --> 06:02.210 we are going to use many of them in the course.
