Abstract
A mobile robot, which enables sure detection of external environments including obstacles around the mobile robot, without being affected by a posture change of the mobile robot, and includes: an obstacle detection sensor, placed on a stage that can sway, which detects an obstacle around the mobile robot; and an actuator which controls a posture of the obstacle detection sensor in a pitching direction by oscillating the stage.

13. A mobile robot comprising:
-
a mobile robot body;
drive wheels which are set on both sides of said mobile robot body;
a rotation control unit operable to control rotations of said drive wheels;
a support, placed on said mobile robot body, which supports a stage;
said stage supported by said support so as to be movable, independently from said mobile robot body, in a pitching direction;
an external environment detection unit placed on said stage; and
an actuator coupled to said support, wherein said actuator controls a posture of said external environment detection unit by driving said stage so that said external environment detection unit is driven in the pitching direction.

14. A method for controlling a mobile robot, said method comprising:
-
detecting an angle between a mobile robot body and a surface on which the mobile robot body moves;
calculating, based on the detected angle, a value indicating an amount necessary for changing a present posture of an external environment detection unit; and
controlling drive of an actuator based on the calculated value so as to control the posture of the external environment detection unit. - View Dependent Claims (15)
