No POSE FEEDBACK

[m-kzein]

There is no pose messages published to the topic "/pose", which makes the drone goes to open loop when a goal way point is provided.

Hello Mohammad,

practically the pose topic of DENMPC and the TUM simulator have to be matched.
You can check which pose topic is published by the TUM simulator with

rostopic list -v

You can adjust which pose topic is subscribed from DENMPC by changing the topic name via the method
setStateSubscriberRosTopicName(...);
You can see a commented example in line 47 of
user_scenarios/scenario.cpp
/src/user_generated/Ardrone_20170227.cpp)
Another possibility is to use the topic remapping capabilities of ROS.

If you want to first get familiar with a working example, there is a turtlebot tutorial available:

Does this help you?
