摘要： A charging pad according to the exemplary embodiment of the present invention may include an input terminal connected to a high-priority charging pad; an output terminal connected to a low-priority charging pad; a charging unit configured to charge a robot positioned on the charging pad in accordance with a preset operating state; and a control unit configured to switch an operating state of the charging unit from an operation stop state to an operation standby state when a status signal for the high-priority charging pad is received from the input terminal. The control unit is configured to output the status signal for the charging pad through the output terminal when occupation of the charging unit by the robot is detected in the operation standby state.

摘要： Disclosed are a method and a system for training an autonomous driving agent on the basis of deep reinforcement learning (DRL). The agent training method according to one embodiment may comprise a step of training an agent through an actor-critic algorithm in a simulation for DRL. The step of training may include inputting first information to an actor network to determine an action of the agent, and inputting second information to a critic to evaluate how helpful the action is to maximizing a reward in the actor-critic algorithm, the second information comprising the first information and additional information.
