The invention relates to an
artificial muscle aggregation group, which is formed by a plurality of
muscle units connected in series, wherein each
muscle unit comprises a plurality of springs as artificial muscles, a front connecting plate and a rear connecting plate which are respectively and fixedly connected with two ends of the springs; the springs are respectively and uniformly distributed along the surfaces of the connecting plates; each spring is internally provided with a guiding-
locking mechanism in a penetrating manner; the two ends of the guiding-
locking mechanism are respectively and fixedly connected with the front connecting plate and the rear connecting plate; the guiding-
locking mechanism consists of a sleeve and a
piston which is sheathed in the sleeve in a slidable manner; one end hidden in the sleeve, of the
piston is provided with a circular convex ring; one end allowing the
exposure of the
piston, of the sleeve is provided with a step for preventing the convex ring from separating from the sleeve; the
muscle unit at the foremost end and the muscle unit at the rearmost end are respectively connected with a high-strength
fiber; and the
artificial muscle aggregation group is also internally provided with a
chaotic characteristic testing module which can judge whether the
chaotic action exists currently and whether the output of displacement or tension of the
artificial muscle aggregation group is qualified. The artificial muscle aggregation group has the advantages that the output of the tension or the displacement amount is large, and the output quality is guaranteed.
