    Abstract: A charging apparatus includes a main body including a charging electrode for charging a robot cleaner, a sensing unit for sensing that the robot cleaner is docked to the main body, and the robot cleaner is electrically connected to the charging electrode, a power supply unit for supplying charging current to the charging electrode, a measuring unit for measuring the magnitude of the charging current provided to the robot cleaner, and a MICOM for recognizing whether the robot cleaner is docked based on information on the magnitude of the charging current measured in the measuring unit. When the measured magnitude of the charging current is less than the magnitude of a set current, the MICOM transmits a first setting signal to the robot cleaner, and based on whether a second setting signal corresponding to the first setting signal is received, the MICOM checks whether the robot cleaner has been docked.
