1. A robot cleaner comprising:
- a main body comprising a receiving unit;
a moving unit to move the main body;
a control unit to control the moving unit;
a voice recognition unit to analyze a pattern of a voice command inputted into the receiving unit to detect whether a call command is inputted;
a direction detection unit to detect a direction in which the call command occurs; and
a detection unit to determine whether the main body is rotatable in the call command occurring direction at a position at which the main body is disposed when the voice command occurs,wherein the control unit is configured to set a linear path (PL) from an initial position (a0) of the main body to a position (s0) of a caller when a call command is inputted,the control unit is configured to determine that the main body is not rotatable in the call command occurring direction when the robot cleaner is docked to a charging platform,wherein, when the main body is not movable in the voice command occurring direction, the main body controls the moving unit so that the main body goes out of the initial position (a0) and moves along a detour route (Pd),after moving along the detour route (Pd), the main body enters into one point in the linear path (PL) to move to the position (s0) of a caller.

Abstract
Provided is a robot cleaner. The robot cleaner includes a main body defining an outer appearance of the robot cleaner, a moving unit for moving or rotating the main body, a plurality of receiving units disposed in the main body to receive a user'"'"'s voice command, and a control unit recognizing a call command occurring direction when the voice command inputted from the plurality of receiving units is a call command. The control unit controls the moving unit so that the main body is moved in the recognized call command occurring direction along the preset detour route.

7. A method for controlling a robot cleaner, the method comprising:
-
receiving a voice command of a user through a receiving unit of the robot cleaner; detecting a direction of a call position at which the voice command occurs; detecting a current position of the robot cleaner; setting a linear path (PL) from the current position of the robot cleaner to the call position; determining whether the robot cleaner is movable from the current position in the direction of the call position along a linear path (PL); moving the robot cleaner in the direction of the call position along a preset detour route when the robot cleaner is not movable along the linear path (PL); entering the robot cleaner the linear path (PL); and ending the movement of the robot cleaner in the call position direction, wherein it is determined that the robot cleaner is not rotatable and not movable in the linear path (PL) in the call position direction when the robot cleaner is docked to a charging platform. - View Dependent Claims (8, 9)
