Hi, folks in Duckietown!
My question is regarding a finite state machine (FSM). As far as I understand, the FSM can be built by the associated yaml file which is essentially made up of states and their events. In the yaml file, an event is implemented in the form of
at_stop_line:
topic: “stop_line_filter_node/at_stop_line”
msg_type: “BoolStamped”
trigger: True
This event sets trigger True but some other events set it False. What does that mean and how is that functioning?
Thanks for your help!
P.S. I’d like to attach the yaml file but in this webpage, there seems no way to do.
