Let's say I have three sonars and three IRs or maybe a servo and one of each. (I don't have any yet.) And I set ALL sets to Radar Collision Detection. Will these work together for obstical advoidance ,or can you use only ONE type at a Time? Important Question. I also have four tiers on the robot so it would need to have possibly four areas to scan. Can they all work together? In you Post, you talked about Either /Or Which would certainly work for small robots, but some of mine are big as you can see from the pictures that I posted.
