Abstract: A computerizable robotic automated bogie is provided including a drive motor and a main drive shaft extending downwardly from the drive motor. A rotatable plate is rotatably coupled to a bottom of a platform and further rotatable with respect to the main drive shaft. A gear mechanism is operatively coupled to the drive shaft. At least one wheel has an axis coupled with the gear mechanism thereby effecting rotation of the at least one wheel about a horizontal axis upon the actuation of the drive motor. The axis about which the at least one wheel rotates is fixed with respect to the rotatable plate. Further included is a rotating mechanism operatively engaged with the rotatable plate for selectively rotating the horizontal axis about which the at least one wheel resides.

Abstract: Apparatus for translating sound into a visual display comprising means for producing audio signals. The audio signals are advanced over a plurality of paths. Over one path, the audio signals are detected for voltage amplitude. Should the voltage amplitude fall within a predetermined range, a valve is operated to control the flow of liquid from a pump to a set of nozzles. Over another path, the audio signals are detected by tone detectors for dominant notes falling within various frequency bands representative of the melody of the audio signals. A resultant voltage is a function of the band of frequencies over which the dominant notes are detected. The flow of liquid from a set of nozzles is proportional to the amplitude of the voltage resulting from the band of frequencies over which the dominant notes are detected. Lamps of various colors are selectively illuminated in accordance with the band of frequencies over which the dominant notes are detected.
