# PX4 Nodes This directory contains several small ROS nodes which are intended to run alongside the PX4 multi-platform nodes in ROS. They act as a bridge between the PX4 specific topics and the ROS topics. ## Joystick Input You will need to install the ros joystick packages See http://wiki.ros.org/joy/Tutorials/ConfiguringALinuxJoystick ### Arch Linux ```sh yaourt -Sy ros-indigo-joystick-drivers --noconfirm ``` check joystick ```sh ls /dev/input/ ls -l /dev/input/js0 ``` (replace 0 by the number you find with the first command) make sure the joystick is accessible by the `input` group and that your user is in the `input` group
