Most modern AGVs employ inductive energy coupling. Consequently, any product used on the AGV must offer ample EMC resistance in order to reliably work in the environment of large electromagnetic fields. AGVs travel along pre-programmed paths that can be changed to address different manufacturing demands. The absolute position of the AGV is determined by reading floor-mounted RFID tags.
Using this information along with data concerning the goods carried by the AGV allows the control system to create a simple lookup table so that the position of all products – on and off the AGV – is always known. This method is also suitable to determine the position of forklifts, cranes, skids, and similar material handling systems.
