Raspberry Pi - ROS installation
This is a guide on how to install ROS-indigo on a Raspberry Pi 2 serving as a companion computer for Pixhawk.
- A working Raspberry Pi with monitor, keyboard, or configured SSH connection
- This guide assumes that you have Raspbian "JESSIE" installed on your RPi. If not: install it or upgrade your Raspbian Wheezy to Jessie.
Follow this guide for the actual installation of ROS Indigo. Note: Install the "ROS-Comm" variant. The Desktop variant is too heavyweight.
Errors when installing packages
If you want to download packages (e.g.
sudo apt-get install ros-indigo-ros-tutorials), you might get an error saying: "unable to locate package ros-indigo-ros-tutorials".
If so, proceed as follows: Go to your catkin workspace (e.g. ~/ros_catkin_ws) and change the name of the packages.
$ cd ~/ros_catkin_ws $ rosinstall_generator ros_tutorials --rosdistro indigo --deps --wet-only --exclude roslisp --tar > indigo-custom_ros.rosinstall
Next, update your workspace with wstool.
$ wstool merge -t src indigo-custom_ros.rosinstall $ wstool update -t src
Next (still in your workspace folder), source and make your files.
$ source /opt/ros/indigo/setup.bash $ source devel/setup.bash $ catkin_make
