Raspberry and ROS

Back to Robobot

Do not use for now

Install Raspberry

Use Raspberry pi imager (download from https://www.raspberrypi.com/software/)

rpi-imager

Select operating system Ubuntu (22.04 64 bit for now) and storage, an empty SD-flash of at least 16GB, then write.

When finished mount the SD into the Raspberry

Start Raspberry

Need a screen and keyboard (mouse not needed) Connect to the network for updating and date/time.

Use the English language Give a username and password

user: local, password:(ask)

Stop the graphical user interface (to save memory)

systemctl set-default multy-user.target
reboot

Allow Ubuntu to update - it takes a rather long time, as a PI3 has got limited RAM.

SSH

Install openssh-server and sshfs

sudo apt install openssh-server sshfs

find your IP address using

sudo apt install net-tools
ifconfig

Install ROS

Will use Noetic (if it is ethical to do so).

Follow the instructions in http://wiki.ros.org/noetic/Installation/Ubuntu

Clone the just installed image

Use SD card copier (on Raspberry??)
