Mobile robot and controller for same
First Claim
1. A mobile robot which communicates by radio with a managing computer via one or more radio base stations coupled to the managing computer and autonomously moves in a movement area through use of map data of the movement area, comprising:
- a radio communication unit for communicating by radio with each of the radio base stations;
a radio environment detecting unit for detecting plural types of radio environment data including radio intensity of a signal received by the radio communication unit in radio communication with the radio base station, which data indicate degrees of goodness of a radio environment of the radio communication;
a comprehensive radio environment data calculating unit for weighting the plural types of radio environment data with predetermined weights and calculating comprehensive radio environment data from results of weighting;
a self-position detecting unit for detecting a position of the robot in the movement area;
a storing unit for storing a map data of the movement area; and
a comprehensive radio environment map creating unit for creating a comprehensive radio environment map for each of the radio base stations by writing the calculated comprehensive radio environment data in association with the position detected by the self-position detecting unit when the radio environment data was detected into the map data stored in the storing unit.

Abstract
A mobile robot includes a radio communication unit; a radio environment detector detecting plural types of radio environment data indicating the degree of goodness of radio environment, a comprehensive radio environment data being calculated from results of weighting the plural types of radio environment data with predetermined weights; a self-position detecting unit; a storage for map data of a movement area; the calculated comprehensive radio environment data being written in association with its own position detected. The robot moves at a movement speed not higher than the maximum movement speed determined so that communication with the radio base station is not cut off during movement and, if radio communication is cut off, searches the radio environment map for a communication restoration position where the radio communication is feasible to establish and moves to the communication restoration position and has the radio intensity reporting control section reporting the determined level of radio intensity.
