Artificial muscle aggregation group

Abstract

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.

Description

technical field [0001] The invention relates to an artificial muscle assembly group. technical background [0002] Artificial muscles have the excellent characteristics of biological skeletal muscles, such as high power density, high efficiency, direct drive, good compliance, and no noise, and have broad application prospects in the field of compliant drives. Due to the limited output force and displacement of a single artificial muscle, and the single form of motion, it is difficult to meet applications such as high output power and multi-degree-of-freedom motion. Therefore, innovative configurations and control driven by a group of artificial muscles have attracted increasing attention. [0003] For example, the Marine Biology Laboratory of Northeastern University has developed a lobster robot. [1] , used for remote autonomous exploration of rivers and coastal bottoms, the lobster robot has 8 legs, each leg has 3 joints, and each joint has 1 degree of freedom, respectivel...

AI Technical Summary

Problems solved by technology

However, under the joint action of a group of artificial muscles, the structural design of the artificial muscle assembly group and the method of tailoring the driving force output are still rarely reported.
