Problems solved by technology

[0007] Although there are drive units based on shape memory alloys at present, they can only bend in one direction, the structure is too complex, the manufacturing is difficult and the cost is high, and they can only be used in specific configurations, which is difficult to meet the requirements of flexible construction and different configurations. Single robot, and it is difficult to adapt to a wider range of operating environments and application requirements

Embodiment Construction

[0034] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0035]It should be noted that if there is a directional indication (such as up, down, left, right, front, back...) in the embodiment of the present invention, the directional indication is only used to explain the position in a certain posture (as shown in the accompanying drawing). If the specific posture changes, the directional indication will also change accordingly.

[0036] In addition, if there are descriptions involving "first", "second" and s...

Abstract

The invention discloses a double-stroke shape memory alloy driven soft module which comprises end plates arranged at two ends, wherein a plurality of shape memory alloy springs are arranged between the two end plates; two ends of the shape memory alloy springs are respectively connected with the two end plates; and the shape memory alloy springs are further electrically connected with a power supply. According to the double-stroke shape memory alloy driven soft module, part of the shape memory alloy springs are powered on, but the other part of shape memory alloy springs are not powered on, so that part of the shape memory alloy springs can be heated and shrunk, and the shrunk shape memory alloy springs pull the end plates at the two ends to tilt and get close to the shrunk shape memory alloy springs, and the other non-powered-on shape memory alloy springs also can be correspondingly stretched to be bent; and therefore, the double-stroke shape memory alloy driven soft module tilts towards a certain direction. Compared with the prior art, the double-stroke shape memory alloy driven soft module has the advantages of simplicity in control, wide application, reliable work and the like.

Description

technical field [0001] The invention relates to the technical field of robot automation control, in particular to a software module driven by a two-way shape memory alloy. Background technique [0002] Robots have been widely used in industrial, agricultural, emergency rescue, military, aerospace and other technical fields, and play an increasingly important role in human production and life. [0003] Traditional robots generally use rigid materials and are connected by kinematic pairs, and their degrees of freedom are small. Although they can achieve high motion accuracy, they also lead to heavy quality, high cost, complex dynamic control, single motion forms, and adaptability to the environment. Poor ability and other shortcomings. [0004] Theoretically, soft robots have unlimited degrees of freedom, can easily realize flexible and changeable movements without complex mechanisms, have strong environmental adaptability, and have flexible contact with the operating objects...
