Bebop has no /cmd_vel or /takeoff topics

edit

The drone I need to use for my thesis is the Parrot Bebop, and I have a simulator built for the purpose of the thesis. I installed everything related to this drone from this github repo

https://github.com/gsilano/BebopS

However, the only control option I have is a position controller based on waypoints, from the bebop_autonomy repo. Since I need to controll the drone from scratch, I need the /cmd_vel topic, however it doesn't show up on my rostopic list. Can anyone help me figure out why? I'm using Ros Kinetic with Gazebo 7.
