ROS instalation #

At the time of summer 2020 there is no way to install noetic on Raspberry Pi OS. That’s why we will build it manually

ROS Noetic build #

Step 1 — Set up ROS Noetic repo on Raspberry Pi 4 #

`1`	`sudo sh -c 'echo "deb http://packages.ros.org/ros/ubuntu buster main" > /etc/apt/sources.list.d/ros-noetic.list'`

Step 2 — Add official ROS key #

`1`	`sudo apt-key adv --keyserver 'hkp://keyserver.ubuntu.com:80' --recv-key C1CF6E31E6BADE8868B172B4F42ED6FBAB17C654`

Step 3 — Pull all meta info of ROS Noetic packages #

`1`	`sudo apt update`

Step 4 — Install build dependencies on Raspberry Pi 4 #

`1`	`sudo apt-get install -y python-rosdep python-rosinstall-generator python-wstool python-rosinstall build-essential cmake`

Step 5 — Set up ROS Noetic dependency sources/repos #

1
2

sudo rosdep init
rosdep update

Step 6 — Fetch & Install ROS Noetic dependencies #

mkdir ~/ros_catkin_ws
cd ~/ros_catkin_ws
rosinstall_generator ros_comm --rosdistro noetic --deps --wet-only --tar > noetic-ros_comm-wet.rosinstall
wstool init src noetic-ros_comm-wet.rosinstall
rosdep install -y --from-paths src --ignore-src --rosdistro noetic -r --os=debian:buster

Step 7 — Compiling Noetic packages on Raspberry Pi 4 #

`1`	`sudo src/catkin/bin/catkin_make_isolated --install -DCMAKE_BUILD_TYPE=Release --install-space /opt/ros/noetic -j1 -DPYTHON_EXECUTABLE=/usr/bin/python3`

Done! #
