Abstract:

    A walking device driven by piezoelectric patches was developed which moves forward by the slight partial elliptical movement of its feet soles. The walking mechanism of the device was analyzed and 3 experimental devices with different vibration angles were made. The effects of the voltage and the frequency of the driving power supply as well as the vibration angle on the movement behavior of the walking device were investigated experimentally. It was found that the device can walk in sliding, jumping and inversing.

Key words: mechanical design, piezoelectricity, vibration, walking device, walking mechanism
