Arduino commands to PIXHAWK - Robot Lawn Mower

[Philip Read]

Hello All,

I'm developing an existing Arduino based robot lawn mower project  ( www.repalmakershop.com ) to work with a PIXHAWK ROVER and Mission Planner.

They will be used to execute missions to mow lawns via RTK GPS.

The current mower is based on Arduino control.  I would like to send commands from the Arduino to the PIXHAWK and the PIXHAWK to the Arduino to:

Start Missions

Stop Missions

Return to Home

etc..

Is this possible with the MAVLINK library and could someone help with sample code to send a command from the Arduino to PIXHAWK.

That would be very helpful so i understand how the code works.

Then i can take it from there to program the logic on the Arduino.

Thanks so much for any help

Phil

Sorry for late response. There is no such thing as Pixhawk Rover - pixhawk is a flight controller hardware not a flight stack. However since you refer to mission planner I assume you mean ArduPilot flight stack.

The short answer is "sure". The commands you need are available in MAVLink. YOu would probably use the python libraries - https://mavlink.io/en/mavgen_python/ or dronekit: https://dronekit-python.readthedocs.io/en/latest/

There should be enough on either of those to work out how to do this. Links to support forums and examples should be available from both those links.
