Abstract
A robot includes first and second microphones and movable portions. The first microphone gathers a first sound reception signal by gathering mainly a target signal. The second microphone gathers a second reception sound signal by gathering mainly noise other than the target signal. The movable portions operate on the basis of the first sound reception signal output from the first microphone and the second sound reception signal output from the second microphone.
