While going through this Page on different types of navigations used in AGV's for Industrial Environments. I came across natural navigation which claims to reduce installation time and cost for the AGV by getting rid of reflectors, localization markers.
So what is Natural Navigation? How does it work? How does it handle Localization and Path Planning? what kind of sensors does it need? Are there any open source implementations of this method.
Any links to research papers/tutorials are welcome
