Cannot use "moving around " keys #18

Hi, I'm using this package with bebop_autonomy but the moving around keys doesn't work The other keys work (t,b,q,z,ecc) I think this might be a problem of the formatting of the commands that are sent when I press the moving keys because I'm also not able to move the drone using rostopic I used different formats but none works: rostopic pub /cmd_vel geometry_msgs/Twist "linear: x: 100 y: 100 z: 100 angular: z: 10" rostopic pub /cmd_vel geometry_msgs/Twist ["100 100 100", "100"] I tried every format but none works

This doesn't really sound like an issue with teleop_twist_keyboard . If you echo the /cmd_vel topic and see then linear and angular velocity changing, then it's working, and your problem is probably somewhere else. (this would also explain why using rostopic pub does not work).

I would check that you're publishing on the same topic that bebop_autonomy is subscribed to. You can see the publishers and subscribers on a topic with rostopic info /cmd_vel .

If that shows that bebop_autonomy is subscribed and the values are being sent correctly, then the problem is likely with bebop_autonomy (or perhaps with your network, if you're running ROS over a network).

If that shows that bebop_autonomy is not subscribed, then it probably uses a different topic name (or maybe isn't running).

In either case, I don't know anything about the bebop_autonomy package, so there's nothing more I can do to help. I suggest you go ask on answers.ros.org with what you've found, and include a link to this ticket in your question.
