issue in launching the controller node #2
Description
after creating the controller node i realized that i need to add it to the launcher file as well.but after doing so i was unable to launch the file as the launcher was somehow not able to locate it.
These are my additions in the launch file:
dynamics = Node(
package = 'single_inverted',
executable = 'dynamics_sim'
)
control = Node(
package = 'single_inverted',
executable = 'controller'
)
return LaunchDescription([
visualizer,
dynamics,
control
])
These are my changes in setup.py
entry_points={
'console_scripts': [
'dynamics_sim = single_inverted.dynamics_sim:main',
'controller = single_inverted.controller:main'
],
this is the error i am facing:
[INFO] [launch]: Default logging verbosity is set to INFO
Task exception was never retrieved
