6 Claims

1. A method of monitoring behavior of a plurality of moving bodies, wherein each of the moving bodies includes:

means for transmitting, as advance information, a movement state including an operation instruction received by the each moving body, together with identification information of the each moving body, and

means for monitoring behavior of the moving bodies,

the method comprising:

designating one of the plurality of moving bodies as a target moving body and causing the target moving body to carry out a reveal operation that enables behavior of the target moving body to be differentiated from behavior of others of the plurality of moving bodies;

each of the plurality of moving bodies generating the operation instruction for controlling an operation of the each moving body;

each of the plurality of moving bodies transmitting the advance information and identification information of the each moving body;

transmitting the reveal operation;

detecting the reveal operation by the means for monitoring the behavior of the moving bodies;

each of the plurality of moving bodies transmitting information concerning a position of the each moving body relative to the target moving body;

receiving the information concerning the positions of each of the moving bodies relative to the target moving body; and

identifying relative positions of the target moving body relative to each of the other moving bodies by monitoring the position information.
