Autonomous traveling body device
First Claim
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.

Abstract
In a first mode, a control unit controls operation of driving wheels so that a main casing is made to travel straight and, upon detection of an object by an object sensor, the main casing is changed in traveling direction and made to travel straight. In a second mode, the control unit controls the operation of the driving wheels so that the main casing travels in a curved shape along an object detected by the object sensor. When a charging device is not found by a signal reception part during traveling within a region by the first mode, the control unit is changed over to the second mode. The control unit is changed over to the first 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 mode.

5. A travel control method for an autonomous traveling body for making a main casing autonomously travel based on detection of presence or absence of an object within a specified distance of the main casing by an object sensor as well as detection of a station device on a traveling surface by a station device sensor, the travel control method comprising:
- a first traveling mode in which the main casing is made to travel straight and, upon detection of an object within a specified distance of the main casing by the object sensor, the main casing is changed in traveling direction and made to travel straight; and
a second traveling mode in which the main casing is made to travel in a curved shape along an object detected by the object sensor, the travel control method comprising;changing 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 changing 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.
- a first traveling mode in which the main casing is made to travel straight and, upon detection of an object within a specified distance of the main casing by the object sensor, the main casing is changed in traveling direction and made to travel straight; and
