ABSTRACT:
The invention is directed to an auditory robot for a human or animal like robot, e.g., a human like robot (10) having a noise generating source such as a driving system in its interior. The apparatus includes a sound insulating cover (14) with which at least a head part (13) of the robot is covered; a pair of outer microphones (16; 16aand16b) installed outside of the cover and located at a pair of positions where a pair of ears may be provided spaced apart for the robot, respectively, for collecting an external sound primarily; at least one inner microphone (17; 17aand17b) installed inside of the cover for primarily collecting a noise from the noise generating source in the robot interior; and a processing module (18) on the basis of signals from the outer and inner microphones for removing from sound signals from the outer microphones (16aand16b), a noise signal from the internal noise generating source. Thus, the robot auditory apparatus of the invention is made capable of effecting active perception by permitting an external sound from a target to be collected unaffected by a noise in the inside of the robot such as from the driving system.
