How can I fly crazyflie with ROS without a joystick?

[chenxlin222]

I have read the tutorial in http://act.usc.edu/publications/Hoenig_Springer_ROS2017.pdf , but I realize that it need a joystick to teleoperate Crazyflie with ROS. How can I fly crazyflie with ROS without a joystick? Because I don't have a Microsoft XBox360 or other controller. Thanks very much!!!

The Crazyswarm does not use (or need) a Joystick. You can find an example without a joystick at https://crazyswarm.readthedocs.io/en/latest/tutorials/tutorials.html.
