Outline of Final Research Achievements

An inchworm-type precision positioning device was optimized. It was revealed that the displacement decreased as the load increases. In order to eliminate the influence of friction, a moving mechanism that generated a non-contact state by levitation was developed. In order to improve the positioning performance, a feedback position control system was implemented. The inchworm-type positioning device which was capable of the positioning with 3 DOF (degrees of freedom) position and 3 DOF orientation was realized by adding the function of inchworm to the mechanism of the parallel mechanism using the piezoelectric element.
