Abstract
A transport system for moving and positioning an object comprising: a tube (24) having an axis of rotation and formed with threads (36) on at least a portion of its surface; at least one platform (126) to which the object (116) is mountable having threads that mesh with the threads of the tube; at least one linear guide (130) along which the at least one platform moves freely that prevents rotation of the at least one platform when the tube rotates about its axis of rotation; and a piezoelectric motor controllable to rotate the tube and thereby selectively translate the at least one platform in either direction along the tube's axis of rotation.
