ARDRONE is not responding to the ros - python code

Question

I tried to run my python code on the real drone but I am getting the below error and the drone is not flying.

Unable to initiate TCP/IP socket to kathirdrone-VirtualBox:55800 (http://kathirdrone-VirtualBox:45968/):
TransportInitError: remote error reported: received a connection for a nonexistent topic [/clock] from [TCPROS connection on port 55800 to [127.0.0.1:58036 on socket 8]] [/forward]

Drone is flying in tumsimulator perfectly with roslaunch cvg_sim_gazebo ardrone_testworld.launch.

My package structure is this. catkin_ws / src / mycode / scripts / DroneFly.py

How can I fix it ?

Answer 1

Issue was with the launch file.

roslaunch ardrone_autonomy ardrone.launch

After the above command, connection is made.

And rosrun mycode

It works finally and the drone is flying
