A new principle for controlled motion of microrobots is briefly described. A controlled vibrating floor allows further miniaturization of each robot by providing additional vertical force to compensate for a reduction of the force available on the three piezo-ceramic legs of each robot due to space constraints. Displacement is only achieved when a miniature robot activates its piezo-legs providing...
A piezo-actuation system based on a three-legged pyramidal configuration with the apex pointing upward and designed to be embedded onto miniature instrumented robots conceived for operations at the nanometer-scale is briefly introduced. The piezo-actuation system is designed to provide small increments required to position an embedded scanning probe microscope (SPM) tip within the range of the instrument...
