An Indoor Positioning System (IPS) is a network of devices used to locate people, robots or objects in an indoor environment, where GPS is lack of precision or fails entirely. Indoor positioning system can provide navigation services in multistory shopping mall, airports, basement carpark, warehouse, tunnel, and underground railway stations. Wi-Fi is frequently applied in indoor navigation and tracking solutions. The advantages of this wireless technology are that the existing Wi-Fi infrastructure can be used for position estimation without login requirement. Position of devices can be estimated based on Received Signal Strength (RSS) from Wi-Fi Access Point (AP). The signal fingerprints or the received signal strength of every location are required to be collected and stored in fingerprint database in order to implement the IPS. However, acquiring signal fingerprints is often a labor-intensive and manual process. Meanwhile, the available solutions for offline Simultaneous Localization and Mapping (SLAM) robots have a mounted data collector that suffers from having accumulative errors. The solution is to use an automatic surveyor to acquire received signal strengths and estimate location with floor tile patterns to label the signal fingerprints.
