WEBVTT 00:00.140 --> 00:07.700 If you decide to install ubuntu 22 on your PC, we can proceed to the installation of the version amble 00:07.730 --> 00:10.010 over Austria during this course. 00:10.010 --> 00:16.010 In fact, you can decide which version of Ros2 to use depending on the ubuntu version. 00:16.010 --> 00:22.160 If you are using ubuntu 22, then you need to install the version that is called Amble of Ros2. 00:22.190 --> 00:29.660 Otherwise, if you prefer using ubuntu 24 then you will need to install the version jazzy of Ros2. 00:29.720 --> 00:35.570 Either way, the code that we will be developing during this course is compatible with both of them. 00:35.990 --> 00:43.280 In this lesson, I'm going to install the version amble of Ros2 as now I am on ubuntu 22. 00:43.280 --> 00:49.100 And also you can find all the commands that I'm going to use in this lesson in a PDF attached to this 00:49.100 --> 00:49.790 lesson. 00:50.780 --> 00:57.860 The installation procedure of Ros2 is very simple, and you simply need to copy paste all the commands 00:57.860 --> 01:03.080 that you can find here at this link that you can also find in the resources of this lesson. 01:03.080 --> 01:07.490 So here actually all of these are the commands that we need to use. 01:07.490 --> 01:09.680 So let's open a new terminal. 01:10.130 --> 01:12.260 Let's place it on this side. 01:12.260 --> 01:16.340 And now let's start copy pasting simply all the commands that we have here. 01:16.340 --> 01:19.640 So let's start with the setting of the local. 01:19.640 --> 01:23.120 So let's copy this command here. 01:25.550 --> 01:31.430 Actually we can ignore the first one as this one only checks for the UTF eight. 01:31.460 --> 01:36.620 Now let's also copy this second command. 01:37.280 --> 01:38.090 Perfect. 01:38.090 --> 01:40.070 And so let's continue like this. 01:40.070 --> 01:44.030 So let's copy also this command. 01:44.030 --> 01:46.760 And also the last one for this section. 01:46.760 --> 01:47.600 Perfect. 01:47.630 --> 01:49.970 Now let's move on to the next section. 01:49.970 --> 01:53.030 That instead is about setting up the sources. 01:53.030 --> 01:55.910 So let's start with the first command. 01:55.910 --> 01:57.980 As always let's paste it. 01:58.010 --> 02:00.470 Then the second command. 02:02.450 --> 02:03.050 Perfect. 02:03.050 --> 02:04.520 So let's press enter. 02:07.640 --> 02:10.520 Now let's move on to the installation of Carl. 02:10.550 --> 02:13.550 So let's copy this one and let's paste it. 02:15.440 --> 02:15.980 Okay. 02:15.980 --> 02:17.750 And now we can use Carl. 02:17.780 --> 02:23.030 So this one here in order to download and set the Ros2 keys. 02:23.060 --> 02:23.930 Perfect. 02:23.930 --> 02:27.050 So we are here so we can copy also this command here. 02:27.050 --> 02:28.940 And we can paste it. 02:28.970 --> 02:31.700 And so now we have set up everything. 02:31.700 --> 02:35.180 So we are ready to install finally the Ros2 packages. 02:35.180 --> 02:38.060 So first we need to update our system. 02:38.270 --> 02:40.040 So let's update it. 02:42.710 --> 02:44.960 Then we also need to upgrade it. 02:45.470 --> 02:48.770 So let's take this one and let's paste it. 02:50.930 --> 02:51.770 Perfect. 02:51.770 --> 02:55.220 And now we can finally install Ros2 humble. 02:55.220 --> 03:01.200 So here we can install the recommended version that is the desktop version that already contains some 03:01.200 --> 03:04.650 very useful packages, such as, for example, RVs. 03:04.680 --> 03:09.780 It contains also some demos and some tutorials that we are going to use during this course. 03:09.780 --> 03:12.780 So let's copy this command and let's paste it. 03:12.780 --> 03:16.770 So this will install a lot of packages as you can see. 03:16.770 --> 03:20.220 So let's wait for the installation of Ros2 to complete. 03:27.900 --> 03:32.790 Once the installation of Ros2 the Humble Desktop version. 03:32.790 --> 03:37.590 So this one here is completed, we can move on to install also this one here. 03:37.590 --> 03:38.940 So this is very important. 03:38.940 --> 03:41.820 So let's copy this command here and let's paste it. 03:41.850 --> 03:45.780 As with this command we are installing the Ros developer tools. 03:45.780 --> 03:46.890 So this one here. 03:46.890 --> 03:52.920 And as we are becoming Ros developers we are going to need many of the tools that are here within this 03:52.920 --> 03:53.700 package. 03:57.390 --> 03:58.260 Perfect. 03:58.260 --> 04:04.320 And as the last step we can see here for the installation is the environmental setup. 04:04.320 --> 04:08.370 So actually we need to set up our Ros2 installation. 04:08.370 --> 04:14.070 So as you can see here our Ros2 is being installed within this directory here. 04:14.070 --> 04:16.470 So in opt Ros amber. 04:16.500 --> 04:19.890 And so actually we can just copy this command here. 04:19.890 --> 04:25.590 And in order to automatically source the Ros2 installation, every time we open a new terminal, we 04:25.590 --> 04:30.720 can insert this line here within a file that is called bash RC. 04:31.260 --> 04:37.950 So if in fact we get the list of all the files that are now in the home directory, we can see that 04:37.950 --> 04:41.130 it exists a file that is called bash RC. 04:41.130 --> 04:45.210 So let's modify this file for example with nano. 04:46.770 --> 04:49.890 So let's modify it the bash RC. 04:50.040 --> 04:52.770 And actually we can go at the end of this file. 04:53.190 --> 04:53.880 Perfect. 04:53.880 --> 04:57.240 So here we just need to paste this command here. 04:57.240 --> 04:59.400 So the one that we have just copied. 04:59.400 --> 05:03.960 So now let's press Ctrl o in order to save these changes. 05:03.960 --> 05:08.400 So let's press enter and then Ctrl X simply in order to exit. 05:08.400 --> 05:09.150 Perfect. 05:09.150 --> 05:14.640 So now if we open a new terminal we should be able to use the Ros2 command. 05:14.880 --> 05:18.870 And so if we use for example the flag minus L perfect. 05:18.870 --> 05:24.210 So now we have the confirmation that actually the ros2 is correctly installed in our PC. 05:24.240 --> 05:30.180 And also we can see that this command here returned a very long list of commands. 05:30.180 --> 05:32.700 So all of these are ros2 commands. 05:32.700 --> 05:34.560 So as you can see here. 05:34.560 --> 05:40.110 And don't worry if for the moment you don't know this command yet or you don't understand the output 05:40.110 --> 05:44.130 of this command, as we are going to use many of these commands here. 05:44.130 --> 05:50.190 So we are going to use many of these ros2 tools in the following reasons Rthy.
