Abstract
A robot cleaner and a method of controlling the robot cleaner are disclosed. The robot cleaner may include a body, a mop, an actuator, a battery, a tank, and a controller. The controller controls a supply of liquid from the water tank to the mop, and the supply of the liquid may be controlled in consideration of a state of the battery. Water injection may be controlled according to an expected use time of the battery, such that the mop can maintain an appropriate water content, and uniform mopping and cleaning can be performed.
Claims18
A robot cleaner, comprising:
- a body;
- a mop rotatably coupled to the body to wipe a floor;
- an actuator configured to rotate the mop;
- a battery configured to supply power to the actuator;
- a tank configured to store liquid;
- and
- a controller configured to manage delivery of the liquid from the tank to the mop,
- wherein the controller manages the delivery of the liquid according to a state of the battery,
- wherein the state of the battery includes an expected use time of the battery, and
- wherein the robot cleaner has the expected use time (t1) based on the state of the battery, and the controller manages the delivery of the liquid from the tank such that the liquid is exhausted in a range of times between 0.9*t1 and t1 from a time point when an operation of the robot cleaner is started.
A robot cleaner, comprising:
- a body;
- a mop rotatably coupled to the body to wipe a floor;
- an actuator configured to rotate the mop;
- a tank configured to store liquid;
- a tube connected to the tank and including an injection nozzle to output the liquid from the tank to the mop;
- a pump provided on the tube;
- and
- a battery configured to supply power to the actuator and the pump,
- wherein an operation of the pump is controlled according to a state of the battery,
- wherein the state of the battery includes an expected use time of the battery, and
- wherein the battery has the expected use time (t1), and the pump is controlled such that the liquid in the tank is exhausted in a time duration in a range between 0 9*t1 and t1 from a time point when operation of the robot cleaner is started.
A method of controlling a robot cleaner having a mop configured to be rotated and wipe a floor, an actuator configured to rotate the mop, a tank configured to store liquid that is supplied to the mop, and a battery configured to supply power to the actuator, the method comprising:
- determining a state of the battery;
- supplying the liquid from the tank to the mop;
- and
- supplying power to the actuator to rotate the mop,
- wherein the supplying of the liquid from the tank to the mop is adjusted according to the state of the battery, and
- wherein the state of the battery includes an expected use time (t1) of the battery such that the liquid in the tank is exhausted in a time duration in a range between 0.9*t1 and t1 from a time point when operation of the robot cleaner is started.
