ABSTRACT:
A plurality of guide lines are provided on a lower traveling field. A first detector is provided with each self-propelled member to detect at least one of the guide lines optically or magnetically. A second detector is provided with each self-propelled member to output a displacement signal which indicates a displaced distance from a predetermined position. A travel controller is provided with each self-propelled member, and performs a feedback control such that the self-propelled member travels on the lower traveling field while tracing the at least one guide line. A plurality of miniature members, each associated with one self-propelled member are placed on a upper traveling field extending above the lower traveling field. The miniature members travel thereon in accordance with the traveling of the self-propelled members through magnetic force. A central controller collectively monitors the displacement signal of each self-propelled member to recognize relative position relationship among the self-propelled members, and issues at least a speed changing instruction and a path-switching instruction for each self-propelled member, based on the relative position relationship. The travel controller of each self-propelled member changes a traveling speed thereof according to the speed changing instruction, and switches a traveling path thereof from the traced guide line to another guide line, according to the path-switching instruction.
