Auto guided vehicle system and operating method thereof

An auto guided vehicle system, adapted to transport an object, wherein the auto guided vehicle system comprises:

• a plurality of auto guided vehicles and each having a vehicle body and an omnidirectional wheel set, and each of the auto guided vehicles further comprising:
• a driving device, configured to drive the omnidirectional wheel set;
• a wireless communication module, configured to communicate with a control module of an electronic device;
• and
• a processing device, coupled to the driving device and the wireless communication module, and configured to transmit a position information to the control module by the wireless communication module,
• wherein the control module determines an arrangement pattern of the auto guided vehicles on a movement plane according an object information of the object and the respective position information of the auto guided vehicles, such that the auto guided vehicles carry and transport the object in the arrangement pattern,
• wherein each of the auto guided vehicles further comprises:
• at least one coding feature element, disposed on a lateral side of the vehicle body, and configured to at least provide a coding information, a direction information and a facing information of the vehicle body;
• and
• at least one image sensor, disposed on the lateral side of the vehicle body, and coupled to the processing device, such that each of the auto guided vehicles senses the at least one coding feature elements of other auto guided vehicle among the auto guided vehicles by the at least one image sensor,
• wherein the coding feature element includes a coding pattern having N×N dot array, wherein N is a positive integer larger than or equal to 3,
• wherein the N×N dot array includes a first pair of dots distributed along a first direction to provide a base line and a second pair of dots distributed along a second direction perpendicular to the first direction to provide the direction information and the facing information with respect to the base line.
