Piezoelectric Actuator for Micro Robot Used in Nanosatellite

Nanosatellites give ideal and cheap ability for space missions focusing on atmosphere research, GPS, scientific activities and other. Seeking to reach the aims of missions there is used special equipment in nanosatellite. One of such devices is piezoelectric robot that is usually responsible for manipulation of functional objects, such as cameras, laser sources, mirrors and other. Piezoelectric bending actuators are widely used for many different applications. One of such applications is precision positioning systems. Precision positioning of the manipulated object is important task for robots used in nanosatellites as well. In this paper authors present new design robot with the piezoelectric actuators for nanosatellites. Investigations are presented and they prove ability to improve the accuracy of the movement for the robotic hand in nanosatellite by using novel piezoelectric actuators that consists of two bending bimorphs.
