Has anyone implemented an “alarm” system for their robot in ROS2?
I have done a search. but to no success.
There seems to be an existing ROS1 implementation by the University Of Florida Machine Intelligence Lab here
(which I myself have never used).
Alarms could be activated by all nodes and be similar to the logging (split into
CRITICAL), but can be cleared by an operator, or can cause downstream effects.
Potential Examples could include:
[INFO] Docking Station Identified
[WARNING] Robot has not moved in n seconds
[CRITICAL] Laser_scan topic has not published in n seconds
Are there any packages out there that can do the same thing? Is there merit and need for this idea, or is it very similar to logging already?
