Autonomous traveler

2:

• The autonomous traveler according to claim 1, wherein
• the information acquisition part acquires an arrangement position of an obstacle as the information.

3:

• The autonomous traveler according to claim 1, wherein
• the information acquisition part acquires a shape of the obstacle as the information.

5:

• The autonomous traveler according to claim 2, comprising
• a cleaning unit for cleaning a cleaning-object surface, wherein
• the control unit sets the traveling route so as to make the main casing travel along a periphery of the obstacle when cleaning the cleaning-object surface by use of the cleaning unit.

6:

• The autonomous traveler according to claim 2, wherein
• the control unit changes a clearance to the obstacle on the traveling route in accordance with the obstacle.

7:

• The autonomous traveler according to claim 1, wherein
• the information acquisition part acquires material of the cleaning-object surface as the information, and
• the control unit sets the traveling route so as to make the main casing preferentially travel on the cleaning-object surface of the same material as the material of the cleaning-object surface at traveling start when making the main casing return to a specified position.

8:

• The autonomous traveler according to claim 5, wherein
• the cleaning unit includes an electric blower for sucking dust and dirt, and
• the control unit changes a traveling speed of the main casing on the traveling route in accordance with the information on the material of the cleaning-object surface acquired by the information acquisition part.

9:

• The autonomous traveler according to claim 1, wherein
• the information acquisition part acquires a step gap on the cleaning-object surface as the information, and
• the control unit sets the traveling route so as to make the main casing travel at least along a direction which intersects a wall surface of the step gap when the main casing passes the step gap.

10:

• The autonomous traveler according to claim 1, wherein
• the information acquisition part acquires the step gap on the cleaning-object surface as the information, and
• the control unit sets the traveling route so as not to ride over the step gap when a height of the step gap acquired by the information acquisition part is equal to or more than a specified value.

11:

• The autonomous traveler according to claim 1, wherein
• the information acquisition part acquires the step gap on the cleaning-object surface as the information, and
• the control unit sets the traveling route so as to start cleaning from a higher position where the step gap exists.

12:

• The autonomous traveler according to claim 1, wherein
• the control unit sets the traveling route so as to make the main casing travel along a boundary between different types of cleaning-object surfaces in the map created by the map generation part.

13:

• The autonomous traveler according to claim 1, wherein
• the information acquisition part acquires a temperature of the obstacle as the information, and
• the control unit sets the traveling route so as not to make the main casing approach within a specified distance when the temperature acquired by the information acquisition part is equal to or above a specified temperature.

14:

• The autonomous traveler according to claim 1, wherein
• the information acquisition part acquires an amount of dust and dirt on the cleaning-object surface as the information, and
• the control unit sets the traveling route so as to make the main casing travel repeatedly in a certain area including the cleaning-object surface when a state in which the amount of dust and dirt on the cleaning-object surface acquired by the information acquisition part is equal to or more than a specified amount remains for a specified period of time or longer.

15:

• A control method for an autonomous traveler, comprising the steps of acquiring information on an outside at autonomous traveling, reflecting the acquired information in a previously-stored map, and setting a traveling route for next autonomous traveling based on the map.
