“…This difference makes that, when heated, the first type tends to compress and the second one tends to expand. Most of the works [20,18,14] focus on the use of homochiral muscles. On the other hand, heterochiral fibers are as best defined in the first paper published, [8], this expansive effect may be of interest for other specific applications.…”

The use of aerial systems in a variety of real applications is increasing nowadays. These offer solutions to existing problems in ways that have never seen before thanks to their capability to perform perching, grasping or manipulating in inaccessible or dangerous places. Many of these applications require small-sized robots that can maneuver in narrow environments. However, these are required to have also strength enough to perform the desired tasks. This balance is sometimes unreachable due to the fact that traditional servomotors are too heavyweight for being carried by such small unmanned aerial systems (UAS). This paper, offers a innovative solution based on twisted and coiled polymers (TCP) muscles. These tensors have a high weight/strength ratio (up to 200 times) compared with traditional servos. In this work, the practical and modeling work done by the authors is presented. Then, a preliminary design of a bio-inspired claw for an unmanned aerial system (UAS) is shown. This claw has been developed using additive manufacturing techniques with different materials. Actuated with TCP, it is intrinsically compliant and offers a great force/weight ratio.

“…To overcome this issue, authors in [14] started using copper wires twisted over the nylon threads, so that the threads could be electrically heated. Authors in [20], on the other hand, used silver covered nylon thread, thought for clothes manufacturing, to obtain better performances in terms of heating transmission.…”

“…Through single-helix approximation method, it is proved that torsional stroke depends on twist number inserted into the fiber and is independent of fiber diameter [26]. While other studies report that the performance of TCP muscles can also be affected by other factors such as annealing stress, arrangement of fibers, turns per a length, weight per a fiber, and temperature of heat treatment [27][28][29][30]. The influence of twisting speed and plies number on the performance of TCP was discussed thoroughly [31].…”

Twisted and coiled polymer (TCP) can generate large stroke and output high power density, making it a promising artificial muscle. Thermally induced muscles fabricated from nylon or other polymer fibers can be used in robotic, biomedical devices, and energy-harvesting equipment. While fibers with different shapes and materials have different optimal process parameters. Understanding mechanisms of TCP forming and the impact of process parameters is critical to explore stronger, more powerful artificial muscles. In this paper, an elastic-rod-theory-based model was established for capturing the quantitative relationship between tensile actuation and fabrication load. Further experimental results agree with model calculation and TCP muscles used in our research reaches maximum stroke of 52.6%, strain up to 9.8 MPa, and power density of 211.89 J/kg.

Studies with coiled polymer fibers have shown their ability to generate work by contracting when heated. The present work introduces a device for automatically manufacturing these coiled polymer actuators (CPAs). Furthermore, a mathematical model for the CPAs is proposed and identified using the least squares algorithm and a solver-based nonlinear optimization method. Finally, a model for a rotational joint driven by antagonistic CPAs is presented and simulated.
