Abstract

Indoor navigation based on Visible Light communication (VLC) are attractive solutions for Indoor Positioning Systems, as Global Positioning Systems signals are strongly absorbed by the buildings and other wireless solutions need to be used. In this work it is proposed an indoor navigation system based on VLC technology for assisting warehouse management with autonomous vehicles. The system is designed to establish bidirectional communication between a static infrastructure and the mobile picking robot. Data transmission uses white tri-chromatic LEDs as optical emitters, a dedicated photodetector with selective spectral sensitivity and different coding schemes designed to ensure synchronization between frames, to shield the decoding process from errors and to minimize flickering effects.
