A robot apparatus is provided. A CPU 15 determines an output of a feeling
model based on signals supplied from a touch sensor 20. The CPU 15 also
deciphers whether or not an output value of the feeling model exceeds a
pre-set threshold value. If the CPU finds that the output value exceeds
the pre-set threshold value, it verifies whether or not there is any
vacant area in a memory card 13. If the CPU finds that there is any
vacant area in a memory card 13, it causes the picture data captured from
the CCD video camera 11 to be stored in the vacant area in the memory
card 13. At this time, the CPU 15 causes the time and date data and the
feeling parameter in the memory card 13 in association with the picture
data. The CPU 15 also re-arrays the picture data stored in the memory
card 13 in the sequence of the decreasing magnitude of the feeling model
output.
