To me, the error: ERROR: cannot launch node of type [drone_control/new_tello_driver_node.py]: Cannot locate node of type [new_tello_driver_node.py] in package [drone_control]. Make sure file exists in package path and permission is set to executable (chmod +x) Seems to be an error of the ROS executor not able to find the binaries for the node new_tello_driver_node.py in the current workspace overlay. Try:
Then try to launch the launch file again. |

Hi Raza
I tried to test if roslaunch works well before connecting the tello drone, but I got this error.
It's the first time I've connected a drone and a HoloLens, so I don't know if it works normally if I connect the drone before roslaunch, or if I'm following your setup well.
Any help would be appreciated.
Thanks
