Emotoinal System with Consciousness and Behavior using Dopamine

Recently, the development of robots other than industrial robots, including home robots, personal robots, medical robots, and amusement robots, has been brisk. These robots, however, have required improvements in their intellectual capabilities and manual skills, as well as further increases in user compatibility (Y. Takahashi, M. Asada (2003)). User compatibility in future robots is important for ease of use, non-fatiguing control, robot friendliness (i.e., sympathetic use), and human-like capricious behavior. However, so far the development of the robots has met with problems with regard to their interactions with humans , especially in relation to motion strategies, communication, etc.. The author has developed a superior automatic piano with which a user can reproduce a desired performance as shown in Figure 1 (E.Hayashi, M.Yamane, T.Ishikawa, K.Yamamoto and H.Mori (1993), E.Hayashi, M.Yamane and H.Mori (1994)). The piano’s hardware and software has been created, and the piano’s action mechanism has been analyzed (E. Hayashi, M. Yamane and H. Mori (2000), Eiji Hayashi. (2006)). The automatic piano employs feedback control to follow up an input waveform for a touch actuator which uses the position sensor of an eddy current to strike a key. This fundamental input waveform is used to accurately and automatically reproduce a key touch based on performance information for a piece of classical music. This automatic piano was exhibited in EXPO 2005 AICHI JAPAN, and a demonstration of its abilities was given.
