Apparatus and method for creating probability-based radio map for cooperative intelligent robots
First Claim
1. An apparatus for creating a radio map in a communication system for cooperative intelligent robots including one or more routing robots for performing signal routing and a mission robot for performing a task, the apparatus being included in a leader robot of the one or more routing robots and comprising:
- a radio signal acquiring unit that acquires information on radio signals between the cooperative intelligent robots;
a radio environment modeling unit that estimates radio strength for each cell of 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,wherein the one or more routing robots are cooperatively operated to securely establish an uninterrupted network between the cooperative intelligent robots by using the radio map to move to a communication region where communication between the cooperative intelligent robots is not disconnected, andwherein the mission robot is configured to use the radio ma to search for a shortest path to a target in the communication region and move to the target.
