Abstract: An automated guided vehicle system may include a plurality of automated guided vehicles arranged in a predetermined relationship with respect to each other for supporting a payload. Each of the automated guided vehicles has a plurality of rollers extending from the automated guided vehicle and engaging a ground surface. Furthermore, at least one locator extends from the automated guided vehicle and engages the payload. Each of the automated guided vehicles also has an on-board controller arranged within a housing thereof, with one on-board controller acting as a master controller and the remaining of the on-board controllers acting as slave controllers. The master controller communicates with the slave controllers to maintain position and speed control of each automated guided vehicle in both a lateral and a longitudinal direction. Furthermore, the slave controllers send feedback information to the master controller.
