<P>PROBLEM TO BE SOLVED: To provide a movable machine system capable of setting a receiving range of an antenna having a stable size, and determining whether or not which of transmission sources exists in the receiving range having the stable size even if a plurality of transmission sources exist. <P>SOLUTION: A robot system is equipped with a teaching operation device 10 for wirelessly transmitting a signal including ID information and TP data, and equipped with two antennas 61, 62 disposed so as to have an overlapped area where a part of the receiving ranges is overlapped with each other, and a signal intensity measuring part 43 for detecting receiving signal intensity when each of the antennas 61, 62 receives a data packet including the ID information and the TP data. The determination part 22 determines whether or not the receiving signal intensity of the two data packets having the same inherent IDs out of the receiving signal intensity of the data packets is not smaller than a determination threshold for determining whether or not the transmission source is positioned in the overlapped area. <P>COPYRIGHT: (C)2011,JPO&INPIT |
