The main difference between an AGV (Automated Guided Vehicle) and an AMR (Autonomous Mobile Robot) is that the AMR uses free navigation, while the AGV localizes itself through physical elements such as QR codes, magnets or rails.
The iw.hub, as an AMR, determines its position based on sensor data and environmental information. The iw.hub uses only the information from its built-in sensors. The implementation does not require any infrastructural changes, so that the iw.hub can perform its first mission within the first day.
