I am planning to use MAVROS setpoint_raw/attitude command to control the body rates of a quadcopter. Can anyone let me know whether this functionality has been implemented in PX4 stack?
In general, I think this has been used before and is working.
For MAVROS in specific I don't know, however, I know that rate control using the SDK which uses the same MAVLink messages internally works (see https://github.com/Dronecode/DronecodeSDK/pull/627).
@BossHater mavros supports bodyrate commands with setpoint_raw/attitude. I am even using the mavros bodyrate commands in my personal project.
