An apparatus for creating a radio map includes a radio signal acquiring unit that acquires information on radio signals between one or more cooperative intelligent robots, a radio environment modeling unit that estimates radio strength for each cell configuring the radio map from the information on radio signals acquired by the radio signal acquiring unit, and a radio map creating unit that classifies a communication region of each cell and models the radio map according to the radio strength for each cell estimated by the radio environment modeling unit.

Apparatus and method for creating probability-based radio map for cooperative intelligent robots

A system achieves seamless localization for a plurality of robots when first some robots moves to a shadow area where GPS signals are not received while remaining second robots receives the GPS signals, by performing an absolute localization for the second robots using the GPS signals; and performing an absolute localization for the second robots using the GPS signals; performing a relative localization for the first robots based on the second robots, thereby determining an absolute location of the first robots. Further, when the second robots move to the shadow area where the first robots have been moved, the system performs the seamless localization by determining a relative location of the second robots based on the first robots on which the relative localization has been performed, thereby determining an absolute location of the second robots based on the relative location of the second robots.
