Hi guys,
Thanks for your feedback.
I'll give it a try on Monday and post my findings! I'll definitely also use
the bumpers, the Roomba does love to bump on things. And if you think about
it using the IR array to avoid obstacles means that it is not a matter if
the Roomba will hit something or not, it's just a matter of when!
