sure, the error was quite long so I did't want to include it in my question.

you are totally right - I passed the object and it actually worked like I expected. Also thanks for your suggestion - th

Greetings,

I am currently trying to write a state machine with smach for a robot, including a safety fuction, where the activity of the robot should be preempted, once a specific message is sent to a certain topic. I tried to modify the example using monitor state and concurrent container: http://wiki.ros.org/mysmach/Tutorials... . My idea was to replace the FOO_CALC state with the state machine of my robot, that is nested in the concurrent container. My code reads as the following: https://github.com/Mrkeyiiii/ROS_Lear...

After rosrun one would get the following message: TypeError: 'StateMachine' object is not callable. I wonder whether there is any work-around for this problem?

PS: It's my first time to ask a question in this platform and I am not sure whether I am doing it correctly. Please let me know if there is anything that I could improve. Many thanks in advance!

Edited: Added error code:

[ERROR] [1552331031.713732]: Error raised during SMACH container construction:
