At the ASCII Club in ASCII, various series and special features that can only be read by members are updated daily.
Today, I would like to introduce ASCII Club's popular article, "I started using NVIDIA" Jetson Nano "because I felt the limits of Raspberry Pie."
Ubuntu 18 on a small computer called Jetson Nano.I put 04 and put ROS Melodic.Jetson Nano is a powerful small computer provided by NVIDIA.I put an OS called Ubuntu and put ROS, a robot middleware.
● Ubuntu 16.I can't find a way to put 04 ...
I started using Jetson Nano because I felt the limit of using Raspberry Pi.Ubuntu 16 on laptop PC (let'snote).I put 04 and ROS Kinetic to move the original wearable robot.However, robots with cables from laptops do not feel wearable.So I decided to use SBC (single board computer) so that SBC was also wearable.
Speaking of SBC, the first thing I started using was Raspberry Pi (Raspberry Pi).The latest Raspberry Pi 4 Model B has 8GB of memory.I wanted to use 8GB of rasp pie, so I first started using Raspberry Pi 4 Model B.Since Ubuntu for raspberry pie is provided, we decided the installation version in light of the Ubuntu version and the ROS version.At that time, I decided to use ROS2 first.Ubuntu 20 that supports both Raspberry 4 and ROS 2 Foxy.I decided to install 04.Although it was installed and did the tutorial, the past assets that were running in ROS cannot be used.It's hard for me of my current technical skills.
So I decided to uninstall Ros 2 and install ROS NOETIC.
But I hit the wall here.
I used a package called "ar_track_alvar" in past assets, but this was not released on Ros NOETIC.When I read this issue, it seems to move, it seems to be moving ...I tried to rewrite it in Vim, but it was impossible with my technology, so I decided to give up quickly and try it on Raspberry Pi 3 Model B.
Buy Raspberry Pi 3 Model B without thinking much, and "Ma Ubuntu 16.04 If you put it in, it will move, right?I was thinking, but I bought it first.
Eh, Ubuntu16.Isn't it the means to put 04 into Raspberry Pi 3 Model B???
Ubuntu 16 for "Unofficial Images" for Raspberry Pi 3 on this page.There is a link to the image of 04, but when you open it, it's "Not Found"??Various "Raspberry 3 Ubuntu 16.04 How to put in "How to put" is finally downloaded from this site.There is no way to down the image!!
Wow, what should I do, my friend gave me advice?
"Why are you using rasp pie?"
Certainly, even if it moves with Raspberry 3, there are not enough memory and it is heavy.I have experienced it in the past.It swaps, but it is hard to say that it is a comfortable development.
My friend left some options.
One of them was "Jetson Nano".The price is not too high and you can do it.
It's a good place to go, but it seems to work.
● Start Jetson nano
The ones purchased are as follows.
・ NVIDIA JETSON Nano Developer Kit B01 ・ Aluminum case for Jetson Nano REV2 ・ AC adapter 5V 4A ・ Samsung Evo Plus 32GB MicroSDHC UHS-I U1 95MB/S
At that time, I purchased it on Amazon because the switch science did not have the stock of Jetson Nano.The case was good for aluminum instead of plastic, so I just purchased the case with switch science.
First, assembly of the case.

It seems that it is not necessary, but I happened to have a silicon grease in my house, so I decided to use it between the heat sink and the case.
