Claim of US Patent No. 10,986,971

1. A charging station of a mobile robotic device comprising:a main housing with an opening;
a signal receiver coupled to the main housing for receiving signals from a transmitter of the mobile robotic device;
a reel disposed within the main housing;
a motor coupled to the reel to drive rotation of the reel in two directions;
a charging cable wound around the reel with one or more magnetic charging contacts on a terminal end thereof, the one or more magnetic charging contacts of the charging cable connecting to corresponding one or more magnetic charging contacts of the mobile robotic device for charging of the mobile robotic device;
an electrical plug coupled to the main housing to connect to a power supply; and
one or more electrical elements electrically coupling the electrical plug to the charging cable and the motor,whereby the charging cable extends through the opening of the main housing by rotation of the reel in a first direction upon the signal receiver receiving signals transmitted from the transmitter of the mobile robotic device and retracts through the opening of the main housing by rotation of the reel in a second direction upon the signal receiver detecting the absence of signals transmitted from the transmitter of the mobile robotic device.
