Abstract

Automatic guided vehicles (AGVs) are widely used in various manufacturing factory such as automobile fabrication factory. The popular guiding method is magnetic induction method, but it needs a lot of effort and time when the travel route is changed. In this study, we proposed a new method to detect the coordinate of an AGV for its auto guiding. The indoor ceiling light emitting diode (LED) lights are utilized as lighting marker, which are modulated with different frequencies. A photodiode is set on the AGV and receive the LED light to determine the coordinates of the AGV. Experimental results showed this new method can achieve enough accuracy under 50cm for AGV coordinate detection.
