Quick Start

In order to run this fuzzer, you need to get your target software installed and running.

The following are installation document links.

• PX4-Autopilot : https://docs.px4.io/master/en/dev_setup/building_px4.html
• QGroundControl : https://dev.qgroundcontrol.com/master/en/getting_started/
• MAVROS : https://docs.px4.io/master/en/ros/mavros_installation.html

If you want to test the PX4 simulator, run it as follows.

python3 4dfuzzer.py

If you want to test using serial communication, run it as follows.

python3 4dfuzzer.py -s [port]

If you want to set it up for each msgid, run it as follows.

python3 4dfuzzer.py -I [iteration]
