ROBOT AND CONTROL METHOD THEREFOR

A robot and a control method therefor are disclosed. The robot may comprise: a plurality of batteries; a first switch for individually supplying, to the plurality of batteries, electric energy provided from an external charger; a second switch for connecting the plurality of batteries; and a processor for controlling the first switch such that, when the external charger is connected to the robot, some of the plurality of batteries are charged on the basis of the SOCs (states of charge) of the plurality of batteries, and then the remaining batteries are charged, and controlling the second switch such that, after the connection with the external charger is disconnected, when a difference in the SOCs of the plurality of batteries reaches a threshold according to the operation of the robot, a battery having a high SOC from among the plurality of batteries charges a battery having a low SOC.
