NorthStar® Navigation System
NorthStar works like an indoor GPS that helps Braava keep track of where it has been and where it needs to go. The NorthStar Navigation Cube projects a signal that Braava uses to determine its location. As Braava cleans, it builds a map of the area, including walls, obstacles and drop-offs as it encounters them. Braava starts by cleaning open areas, moving methodically back and forth across the floor in parallel lines and following up with a perimeter sweep for a complete clean.
