Title
An Enhanced Artificial Muscle Module Based On The Decussate Weaving Shape Memory Alloy Wires For Soft Robots
Abstract
Artificial muscle has been more and more widely used in the field of bionic robots because of its better flexibility, lightness, etc. Shape memory alloy ( SMA) wires are widely used as driving materials for artificial muscles rather than other smart materials due to their similar mechanical behaviors to skeletal muscles and capabilities of high power to weight ratio. However, their further applications in artificial muscles are limited because their low contractive strain compared with human or animal muscles. This paper presented a new enhanced artificial muscle module based on decussate weaving SMA wires for soft robots. The thermo-mechanical model and simulation were carried on the artificial muscle modules. Then, several kinds of artificial muscle modules with different weaving angles were fabricated based on casting technology. Besides, tension tests were carried on them and the results showed that the maximum strain is 5.82% with the weaving angle of 40 degrees, which increased by 34.81% comparing to the one without weaving. This proves the feasibility of the decussate weaving in the design of SMA wires-based artificial muscle modules and could improve the effective strain of the SMA wires artificial muscle modules significantly.
