PX4 Low Level Offboard Control using ROS 2

This package is an example of how to control a PX4 Multi-rotor Vehicle in offboard mode with Low-level commands through ROS 2.

By Low-level commands, we mean that the commands that are sent to PX4 are either:

1. Attitude Setpoints (Collective Thrust + Attitude),

2. Thrust + Torque setpoints

3. Direct Actuator commands (throttles of the motors).

You can switch between the different control modes using ROS 2 parameter.

This videos below shows a simulated quadrotor controlled with this package with Direct Actuator commands.
