Robot system and control method of the same

1. A method for controlling a robot system, which comprises: a driving source; a rotation arm rotating by the driving source; and a vehicle service robot installed on the rotation arm, the method comprising:

entry processing of a vehicle when the vehicle enters;

preparing charging of the vehicle;

allowing the vehicle service robot to connect a plug to a charging port of the vehicle after the rotation arm rotates by the driving source so that the vehicle service robot moves to a position adjacent to the charging port of the vehicle in a state of holding a plug of a charger; and

charging the vehicle,

wherein the entry processing of the vehicle comprises:

allowing a vision sensor to sense a license plate of the vehicle;

confirming a position of the charging port of the vehicle according to the license plate;

determining a charging service robot for servicing the vehicle of which the license plate is sensed among a plurality of charging service robots; and

guiding the vehicle to a parking area corresponding to the determined charging service robot.

2. The method according to claim 1 , wherein the preparing charging of the vehicle comprises:

allowing a customer to pay a service cost; and

allowing the vehicle to be standby for charging after a payment of the service cost.

3. The method according to claim 2 , wherein the allowing the vehicle to be standby comprises:

allowing the vision sensor to re-sense the license plate of the vehicle; and

confirming whether the license plate recognized in the entry processing of the vehicle is the same.

4. The method according to claim 2 , wherein the allowing the vehicle to be standby comprises:

allowing at least one of the vision sensor or an ultrasonic sensor to sense whether the vehicle gets out of a parking area,

allowing the vision sensor to sense start-off of the vehicle, door opening of the vehicle, and getting off of the customer;

allowing the vision sensor to sense whether a nearby object to approaches the vehicle, the vehicle service robot, or the charger; or

generating an announcement for limiting riding or getting off of the customer.

5. The method according to claim 1 , wherein the allowing the vehicle service robot to connect a plug to a charging port comprises:

allowing a vision camera to recognize a position of a port cover;

allowing the vision camera to approach surroundings of the recognized position and sense a type of port cover, and allowing the vehicle service robot to open the port cover; and

allowing the vehicle service robot to connect the plug to the charging port,

wherein, when the plug is connected to the charging port, a position, force, and rigidity of the plug are controlled.

6. The method according to claim 1 , further comprising separating the plug from the charging port of the vehicle,

wherein the separating of the plug comprises:

allowing the vehicle service robot to separate the plug from the charging port when the charger receives a charging completion signal from the robot; and

allowing the vehicle service robot to move so that the plug returns to the charger.

7. The method according to claim 6 , further comprising:

preparing exiting of the vehicle; and

processing the exiting of the vehicle,

wherein the preparing of the exiting of the vehicle comprises:

allowing a vision sensor to sense a closed state of a port cover that covers the charging port;

allowing the vision sensor to inform an opened state of the port cover when the port cover is in the opened state; and

allowing the vision sensor to sense surroundings or a vehicle state,

wherein preparing exiting of the vehicle comprises:

resetting the vehicle service robot; and

informing charging completion to a customer.
