Abstract
Disclosed are a robot cleaner and a self testing method thereof. The robot cleaner performs a self test when being initially operated or when required by a user. This may prevent malfunctions or breakdowns of the robot cleaner. Furthermore, the robot cleaner senses states of components and sensors mounted therein, and performs a self test based on characteristics, output values, etc. of the components and the sensors. This may prevent accidents or errors which may occur as the robot cleaner operates.
Claims18
A robot cleaner comprising:
- a body which forms an appearance;
- a driving unit having a wheel motor to rotate right and left main wheels provided at two sides of a lower part of the body, and to move the body by driving the wheel motor;
- a storage unit to store a test algorithm;
- a state sensing unit to sense a state of units provided within the body and to output a first sensing information;
- an object sensing unit to sense periphery objects from the robot cleaner and to output a second sensing information;
- an operation sensing unit to sense changeable operations according to a movement of the robot cleaner and to output a third sensing information;
- an input unit to receive an execution command of a self test mode;
- a controller to execute the self test mode according to the test algorithm when the execution command is received, and to test the robot cleaner by receiving at least one of the first, second and third information;
- and
- an output unit configured to output an execution result of the self test mode, wherein each the sensing information is outputted while the robot cleaner moves in a predetermined pattern within a preset distance from a charging base according to the test algorithm, wherein the preset distance is shorter than a maximum distance at which the object sensing unit is allowed to sense the charging base so as to determine that the object sensing unit is in an abnormal state according to whether the object sensing unit senses the charging base or not.
