Abstract

The authors report the motion of a miniature three-legged robot consisting of three piezoelectric elements operated by rectangular voltage. The small leg displacement is measured precisely by three optical sensors. We detail the relationship between leg motion legs and control signals applied to piezoelectric elements. The robot rotates in the CW and CCW directions, yielding interesting results. Step displacement is synchronized with control waveforms.
