An Innovative 3D Ultrasonic Actuator with Multidegree of Freedom for Machine Vision and Robot Guidance Industrial Applications Using A Single Vibration Ring Transducer

Abstract

This paper presents an innovative 3D piezoelectric ultrasonic actuator using a single flexural vibration ring
\ntransducer, for machine vision and robot guidance industrial applications. The proposed actuator is principally
\naiming to overcome the visual spotlight focus angle of digital visual data capture transducer, digital cameras and
\nenhance the machine vision system ability to perceive and move in 3D. The actuator Design, structures, working
\nprinciples and finite element analysis are discussed in this paper. A prototype of the actuator was fabricated.
\nExperimental tests and measurements showed the ability of the developed prototype to provide 3D motions of
\nMultidegree of freedom, with typical speed of movement equal to 35 revolutions per minute, a resolution of less
\nthan 5μm and maximum load of 3.5 Newton. These initial characteristics illustrate, the potential of the developed
\n3D micro actuator to gear the spotlight focus angle issue of digital visual data capture transducers and possible
\nimprovement that such technology could bring to the machine vision and robot guidance industrial applications.
