FSMs are a boon in our behavioural robotics projects. If you have read the
Rod Brooks papers, he uses them to implement subsumptive architectures in his
"radical" robots. I have used them a LOT in my Stamp II robots as the only way
to get a form of task interleaving in a microcontroller that is essentially one
linear process. I haven't considered them much in NQC as the RCX has a 10 task
multitasker, it didn't seem essential for most things. The behaviors that I
have implemented had only a few states anyway and the lack of switch statements
didn't get in the way.
What kind of tasks have you been implementing with FSMs in your projects?
I'm kinda interested in the path you are taking.
Cool subject,
