Proposed inchworm actuator used as active truss member, length of which varied slowly to change configuration of truss rapidly or to counteract vibrations. Incorporates three piezoelectric actuators. Upper and lower piezoelectric actuators unlock normally locked clutches. Middle piezoelectric actuator enforces small variations of distance between clutches. Inchworm actuator holds its position when electrical energy was not supplied.
