Abstract

A micropositioner has been constructed with a piezoelectric tube and walking pads locked by magnets. These magnets were arranged in a special geometry to prevent slipping and trapping. The magnetic force created was large enough to operate the walker in any orientation. Tolerance of surface roughness was much higher than other similar types of micropositioners.
