Connecting the Pixhawk FMU to a Raspberry Pi 2

 

Project Recap:

My Masters project within the Bristol Robotics Laboratory is to design a system of UAVs that can be deployed in groups to co-operatively map the structure of their environment.  This is envisaged as an internal environment, however it is expected that the technologies developed may be additionally adapted for external mapping.  This series of posts documents key elements of the project.  So far we have set the objectives and built an airframe based on a standard 450 quadcopter configuration.

Post Objective:

An on-board Raspberry Pi will have overall control of the UAV.  This post shows how we can set up communications between the Raspberry Pi 2 and a Pixhawk flight management unit,  using the Mavlink messaging protocol, so that the Raspberry Pi can take control of navigation.
