1. An autonomous traveling body device comprising;

  • a station device installed on a traveling surface; and

    an autonomous traveling body including;

    a main casing;

    a driving wheel for enabling the main casing to travel on the traveling surface;

    an object sensor provided in the main casing and serving for detecting presence or absence of an object within a specified distance;

    a station device sensor for detecting the station device; and

    a control unit for controlling operation of the driving wheel based on detection by the object sensor and the station device sensor to thereby make the main casing autonomously travel, whereinthe control unit has a first traveling mode for controlling the operation of the driving wheel so that the main casing is made to travel straight and, upon detection of an object by the object sensor, the main casing is changed in traveling direction and made to travel straight, and a second traveling mode for controlling the operation of the driving wheel so that the main casing travels in a curved shape along an object detected by the object sensor, and wherein the control unit is changed over to the second traveling mode when the station device is not found by the station device sensor during traveling within a region by the first traveling mode, and the control unit is changed over to the first traveling mode when it is decided a specified number of times or more that the main casing has moved to a different region by the second traveling mode.
