I read that there are extra "beacons" available for Rovio. Why would you need them? Is Rovio limited to only one room without those extra beacons?

Does Rovio have obstacle recognition - go around sofas, etc., by itself?

Does Rovio have an autonomous mode, or must all its moves be programmed?

Thanks

The beacons are only required for Rovio's autonomous navigation (driving itself and self docking). The beacons are used by Rovio to tell where it is in a room and what room it is in. If you are driving Rovio manually, then the only thing you need is a good WiFi signal to send commands and receive audio and video. When driving manually the range and strength of the WiFi signal coming from the charging dock, shown with the WiFi strength indicator on Rovio' web interface, will determine how far you can go throughout your home. If you have good WiFi strength throughout your home, then you can drive Rovio wherever you want inside it (except up stairs).

But if you want Rovio to be able to drive itself throughout your home without your intervention, using a patrol route you created with the browser interface, you will need coverage for every room on the patrol route's path and that coverage will have to be contiguous. By contiguous I mean that there can be no gaps in the patrol route path where there is a room that does not have a beacon. Let's say you have a bedroom that is connected to a hallway which then connects to your dining room. You would have to have a beacon in the bedroom, the hallway, and the dining room if you wanted to create a patrol route for Rovio that navigated that path. If the hallway did not have a beacon, thereby creating an area between the bedroom and the dining room that did not have a beacon, Rovio could not self-navigate a path that involved those three rooms. You could still drive it manually through those 3 rooms, but not create a patrol route through them.

Does that help? Also, welcome to the forum. Smile

Thanks for the reply.

Yes, now I understand why the beacons are needed.

Can the Rovio maneuver around obstacles by itself. Suppose I program a route and then later someone puts an object in the middle of that route. What would Rovio do? Would Rovio get stuck? Do I have to re-program the route?

Also, is there a real autonomus mode, like Roboquad for instance, where Rovio explores a room, then at a set time in its program, returns to its dock?

It is my understanding the Rovio will go around obstacles, since it has IR detectors for that purpose. I'll want to test it myself first before I state that with confidence, but that is my understanding.

There are two ways to look at your question:

1) Scheduled patrol routes
2) Autonomous exploration without any patrol route (like Roboquad does)

The answer is simple here because Rovio does neither. Smile

However in case #1, I would expect that soon you would be able to schedule a patrol route to be executed at a certain somewhere in the near future since it's a pretty simple feature for WowWee or someone else to add. Rovio would then execute the patrol route at the appointed time and send you pictures from all the key waypoints on the patrol route.

Case #2 is much more difficult because the consequences of Rovio getting stuck and running out of power are a big problem for a remote monitoring vehicle. If you're away from home, you're dead until you return if Rovio loses power completely. Also, it would require much more sophisticated navigation and room analysis algorithms. The essence of creating a good patrol route is to create a path for Rovio that goes through areas of your home that are nearly guaranteed to be obstacle free. That greatly simplifies the algorithm Rovio needs when it comes to understanding its environment, compared to something like the NASA Mars rover which has free roaming capability.

Thanks for the detailed replies. I'm looking forward to more reviews when the extra beacons are used.
