mavlink_ros ROS package

The mavlink_ros package is a serial MAVLink to ROS bridge. This ROS package created a node that allows to send and receive MAVLink packets through a serial interface.

The mavlink_ros ROS package was initially coded by Lorenz Meier for rosmake (old ROS versions). An updated (catkinized) package is available here.

Compiling mavlink_ros

To use mavlink_ros you just need to clone the repository at ~/catkin_ws/src directory:

cd ~/catkin_ws/src
git clone https://github.com/y22ma/mavlink_ros

Then we need to compile the package with catkin_make:

cd  ~/catkin_ws/
[email protected]:~/catkin_ws# catkin_make
