Hi,

based on the page link text

I have launched after adaptation for the gazebo garden a X3 drone example:

console #1: gz sim quadcopter.sdf

console #2: gz topic -t /X3/gazebo/command/motor_speed --msgtype gz.msgs.Actuators -p 'velocity:[700, 700, 700, 700]'

And it works, I can control the motors independently (what I need). I am now trying to incorporate ROS2 into the task. How to build a bridge for this topic?

The start is probably there, but what next?

ros2 run ros_gz_bridge parameter_bridge /model/X3/????????????

The mapping for that message type is currently not implemented in ROS 2 (https://github.com/gazebosim/ros_gz/t... look for Actuators and see TODO). It is implemented for ROS Melodic since the corresponding ROS message mav_msgs/Actuatorsis available in Melodic (see https://github.com/gazebosim/ros_gz/t...), but not in later versions.

My recommendation would be to use the MulticopterVelocityControl system as shown in this example.
