1. An autonomous mobile robot system comprising:

  • a mobile robot; and

    a computing system;

    wherein the mobile robot includes;

    a sensing section for measuring surrounding conditions of the mobile robot;

    a position-posture estimating section for estimating position-posture data from sensing data obtained by the sensing section and an environmental map; and

    a robot moving section for controlling movements of the mobile robot according to movement control data determined from the position-posture data thus estimated and movement route data; and

    wherein the computing system includes;

    an environmental map generating section for generating the environmental map indicating environmental geometric conditions including objects present in an environment where the mobile robot is to move around;

    a movement route data creating section for creating the movement route data for movements of the mobile robot in a coordinate scheme of the environmental map; and

    a predictive collision probability parameter calculating section for determining a value of a collision probability parameter indicating a level of predictive probability of collision of the mobile robot with an object in mobile robot movements with inclusion of control errors through calculation by using robot composition information regarding the mobile robot, the environmental map thus prepared, and the movement route data thus created.
