Roomba example doesn't work

edit

Hello,

I just tried the Roomba example, which shows how Finite-state-machine using decision_making package should be implemented. I think that conditions are not checked correctly, on the other hand the Turnstile is working, but because the events are generated on event topic.

Does somebody had/have the same problem? Because I am not sure if I am doing something wrong or it implementation bug.

Thanks!
