	In this project, we installed ROS2 using Debian packages (from binary packages) on RPi 4. ~~Installing~~ using Debian packages ~~is more convenient~~ because it automatically installs all of the required dependencies. It also receives updates at the same time as the rest of the system.		In this project, we installed ROS2 using Debian packages (from binary packages) on RPi 4.

			then you can add repository to sources list:

	ii) Install ~~ROS2~~ Packages		echo "deb [arch=$(dpkg --print-architecture) signed-by=/usr/share/keyrings/ros-archive-keyring.gpg] http://packages.ros.org/ros2/ubuntu $(source /etc/os-release && echo $UBUNTU_CODENAME) main" \| sudo tee /etc/apt/sources.list.d/ros2.list > /dev/null


			==== Install ROS 2 Packages ====

			After adding repository, you will have to update apt repository:

			sudo apt update

	~~iii) Environment Setup (sourcing the setup script).~~
