Abstract
A robot cleaner includes a body to travel on a floor, an obstacle sensing unit to sense an obstacle approaching the body, an auxiliary cleaning unit mounted to a bottom of the body, to be extendable and retractable, and a control unit to control extension or retraction of the auxiliary cleaning unit when the obstacle is sensed, through adjustment of an extension or retraction degree of the auxiliary cleaning unit.
Claims34
A robot cleaner comprising:
- a body to travel on a floor;
- an obstacle sensing unit to sense an obstacle approaching the body;
- an auxiliary cleaning unit mounted to a bottom of the body, to be extendable and retractable;
- and
- a control unit to control extension or retraction of the auxiliary cleaning unit by adjusting an extension or retraction degree of the auxiliary cleaning unit when the obstacle is sensed.
A robot cleaner comprising:
- a body to travel on a floor;
- an obstacle sensing unit to sense an obstacle approaching the body;
- at least one auxiliary cleaning unit mounted to a bottom of the body, to be extendable and retractable;
- and
- a control unit to control extension or retraction of the auxiliary cleaning unit in accordance with a shape of the sensed obstacle when the obstacle is sensed.
A robot cleaner comprising:
- a body to travel on a floor;
- an obstacle sensing unit to sense an obstacle approaching the body;
- at least one auxiliary cleaning unit mounted to a bottom of the body, to be extendable and retractable;
- and
- a control unit to control extension or retraction of the auxiliary cleaning unit in accordance with a travel direction of the body when the obstacle is sensed.
A robot cleaner comprising:
- a body to travel on a floor;
- an obstacle sensing unit to sense an obstacle approaching the body;
- an auxiliary cleaning unit mounted to a bottom of the body, to be extendable and retractable;
- and
- a control unit to control extension or retraction of the auxiliary cleaning unit in accordance with a cleaning mode of the body when the obstacle is sensed.
A control method for a robot cleaner comprising:
- driving a body of the robot cleaner such that the body travels on a floor;
- sensing an obstacle approaching the body;
- and
- controlling extension or retraction of an auxiliary cleaning unit mounted to a bottom of the body, to be extendable and retractable, by adjusting an extension or retraction degree of the auxiliary cleaning unit.
A robot cleaner comprising:
- a body to travel along a floor;
- a main brush unit;
- a power supply,
- first and second drive wheels;
- a caster;
- at least one auxiliary cleaning unit, the auxiliary cleaning unit being extendable and retractable in a radial direction of the body, and comprising;
- a side arm coupled to a front portion of a bottom of the body at one side of the body, the side arm being pivotable about a first coupling groove formed at one end of the side arm;
- a second coupling groove formed at an other end of the side arm;
- an auxiliary cleaning tool rotatably coupled to the second coupling groove;
- and
- a periphery cover attached to the other end of the side arm, the periphery cover forming an outer surface of the body when the auxiliary cleaning unit is in a fully retracted position,
- an obstacle sensing unit to sense an obstacle approaching the body;
- a control unit to control extension or retraction of the auxiliary cleaning unit,
- wherein the control unit adjusts the extension or retraction of the auxiliary cleaning unit based on a pivot angle of the side arm with respect to a travel direction of the body.
