Abstract: A light receiver 212u provided on the upper side and a light receiver 212d provided on the lower side with respect to the optical axis of a light emitter 211 generate light reception signals corresponding to the light reception intensity of emitted light from the light emitter 211. A liquid level state determiner 30 determines a liquid level state on the basis of a signal level difference between the light reception signal generated by the light receiver 212u and the light reception signal generated by the light receiver 212d. It is not required to perform processing of captured image data, and even in a case where a liquid temperature is substantially equal to the outside air temperature, the state of a liquid level can be easily grasped.

Abstract: To generate motion data of a motion in synchronization with a melody of music. As an embodiment of the present invention, when motion pattern data corresponding to a predetermined motion pattern is stored, music data is analyzed to detect a beat of music based on the music data, and the music data is divided into a plurality of bar intervals based on the detected beat, the motion pattern data is allocated to the bar intervals of the music data being divided to generate motion data. In this manner, when the motion data is reproduced together with the music data, the motion pattern can be switched in synchronization with switching of first bar intervals and second bar intervals corresponding to a bar when the music based on music data is expressed in a musical score.

Abstract: A legged robot is provided with a plurality of basic motion programs. The legged robot can produce a teaching motion program for performing a series of expressive motions by recognizing and language-processing instructions from a user in the form of voice-input, and extracting and combining at least one basic motion in a time series. More sophisticated and complex teaching programs can be edited by controlling the produced teaching motion programs stored in a database and combining the teaching motion programs with the basic motion programs.

Abstract: A legged mobile robot realizes a motion language by a time-series change in an actuator angle or a motion pattern using the four limbs and the trunk. A motion language which includes, for example, a motion pattern which is an approximation of the contour/shape of a character is used, so that even a robot or a human being which does not possess the same motion language database can determine the meaning and character which is indicated by each motion pattern as a result of visually recognizing and interpreting the contour/form which is indicated by each motion pattern. For example, a robot which has stepped into a dangerous working area can give a message concerning, for example, the condition of the working area to an observer at a remote location without using any data communications device. The legged mobile robot communicates by moving the limbs and/or the trunk.
