To allow a robot device to identify an interactive object and take desirable action depending on thereto.

The robot device comprises an action learning means for making the robot device learn input information concerning the interactive object and then learn highly evaluated action with a RNN 100 and an action control means for identifying the interactive object from the input information concerning the interactive object in accordance with the learning result and presenting the action having a high evaluation value learned by the action learning means depending on the identified interactive object with an inverse RNN (RNN-1).
