Error while running Teleop

[dsriaditya999]

Hello,

Thank you for sharing such a good resource. I had followed all the steps for installation but I am getting an error when I run the following line:

rosrun mavros_off_board teleop_node_pos

It says that it could not find the executable teleop_node_pos. I noticed that there is no mention of this in the CMakeLists.txt. Can that be a reason?

It would be great if you look into this. Thank you!

Hello, Same problem here. I even did what @MikeS96 answered in Q3 in https://github.com/MikeS96/autonomous_landing_uav/issues/9#issuecomment-948625474 and in https://github.com/MikeS96/autonomous_landing_uav/issues/9#issuecomment-949650526

as @MikeS96 said in https://github.com/MikeS96/autonomous_landing_uav/issues/9#issuecomment-949650526, if I run

rosrun mavros_off_board teleop_node_pos.py

I get error below

Hi @dsriaditya999, please see https://github.com/MikeS96/autonomous_landing_uav/issues/9#issuecomment-948625474.

@Comor543 it seems like it is having problems finding the teleop_twist_keyboard package, have you tried sudo apt-get install ros-noetic-teleop-twist-keyboard?

[Comor543]

Hello @MikeS96 thank you for considering our problems. I install ros-noetic-teleop-twist-keyboard by sudo apt-get install ros-noetic-teleop-twist-keyboard as you said and works for me. However, before I was informed you answered my question I just commented roslib.load_manifest('teleop_twist_keyboard') in file teleop_node_pos.py then run catkin_make and it worked too.

import roslib; # roslib.load_manifest('teleop_twist_keyboard')

This way it works for me, but IDK why :D. Just wanted to inform you.
