“…As proof of the concept, a 0.4 g NR/KC band with an initial length of 6 cm is stretched to 40 cm by hanging a 100 g weight (Figure c and Movie S1). The weight can be easily lifted under the hot air blowing, demonstrating the thermal-responsive retraction behavior of NR/KC with a power density of 637J/kg, which is 50 times higher than that of mammalian muscle and also performs well in other studies of artificial muscles in Figure d. − Similarly, in Figures S5 and S6, the muscle-mimicking retraction function of NR/KC after adding nigrosin can also be triggered by electricity or infrared laser based on the joule heating effect or photothermal effect, respectively (Movies S2 and S3). These demonstrations show the scalability and great potential of NR/KC in thermal-responsive applications.…”

Natural rubber (NR) material is indispensable in various fields of our daily life, while its preparation usually involves toxic cross-linking agents and energy-consuming vulcanization processes. The permanent cross-linking network of NR products also makes its degradation and recycling difficult. Herein, a fully biosourced, vulcanization-free NR material is developed by simply introducing carrageenan (KC) in the rubber matrix via a facile aqueous mixing method. The nonrubber components (NRCs) on the rubber latex particles are of crucial importance for this art as they can interact with KC by forming hydrogen bonding between the functional groups of proteins in NRCs and the abundant hydroxyl and sulfonate groups on KC molecules. As a result, KC is selectively dispersed between the latex particles and forms a segregated filler network. The special KC network and the good interfacial interaction between KC and rubber promote strain-induced crystallization and endow rubber composites with great mechanical properties. Moreover, the obtained NR/KC composites exhibit an interesting thermalresponsive attraction behavior, which has good potential in smart applications, such as artificial muscle. This work paves a simple and effective path to vulcanization-free NR by leveraging the inherent NRC on latex rubber particles, opening a new horizon for the sustainable development of NR/polysaccharide composite elastomers.

“…Some fabric artificial muscles have humidity‐adaptive breathability, which can provide a good reference for further development of BFAM. [ 37 ] The analytical model we established can predict the force and motion of actuator in general, yet the model is only for the quasistatic state. A dynamic model for achieving precise real‐time control should be developed in future work.…”

In wearable robotics, soft actuation principles have been increasingly explored and tested due to their safety and comfort in human–robot interactions. Herein, a braided flat‐tube artificial muscle (BFAM) is presented. BFAMs are fabricated by braiding cotton threads together with an inexpensive lay‐flat tube (LFT) in a specific conform‐to‐LFT weaving method. They generate uniaxial contractions when powered by compressed fluids. The basic structure and working mechanism of the proposed BFAM are explained, and a quasistatic model is also developed. A comparison with other fluidic driven soft actuators is made and tabulated. Based on experimental studies, the proposed BFAM can contract close to 30% and yield force outputs more than 150 times their weight at an air pressure of 0.12 MPa. BFAM can be braided with multiple layers of flat tube without large increase of size. Experimental studies have shown that more layers of flat tube give a larger strain and output force up to four layers, beyond which layer increase does not yield visible improvement in strain and output force. Finally, potential applications of BFAM to arm joint actuations are illustrated to show its easy fitting to wearable robotics.

“…Artificial muscles have been accomplished by using various smart materials and compliant structures, showing promise in unstructured and dynamic environments due to their adaptability, flexibility, and resilience. − Artificial muscles are frequently employed as actuators in soft robotic systems, enabling grasping and twisting. Soft robotic grasping has been accomplished by using various types of artificial muscles, including pneumatic soft actuators, − smart materials, − and adaptive mechanisms. − In parallel, soft robotic twisting has also been realized based on different approaches. However, twisting motions in these studies can only achieve a very limited rotation angle and are not independent as they are often coupled with other motions, such as bending and linear motions. − Moreover, robotic gripping and twisting motions are rarely achieved simultaneously in the same design.…”

Grasping and twisting motions are vital when manipulating objects due to their fundamental role in enabling precision, adaptability, and effective interaction. However, few studies in soft robotics exploiting artificial muscles have achieved object manipulation in situ through the coordination of twisting and grasping motions akin to our forearm and hand's capabilities. Especially, when using the same artificial muscle module to achieve these two motions will greatly simplify the manufacturing and control complexity. Here, we introduce identical origami artificial muscle modules (OAMMs) subjected to distinct end constraints into the design of the robotic manipulator, allowing it to achieve independent grasping and twisting motions to achieve effective, precise object manipulation. Applying different end constraints to the identical OAMMs yields distinct motions at their ends, where utilizing a fixed end and a sliding end realizes pure translation, while opting for a fixed end and a rotating end enables pure rotation. The differentially constrained OAMMs then serve as soft actuators for the manipulator's torsional mechanism and grasping mechanism to accomplish independent, controllable twisting and grasping motions. The coordination of twisting and grasping motions finally enables the manipulator to complete various tasks, including installing a light bubble, pouring the water from a lidded bottle into a cup, and sorting and stacking puzzle blocks. Our study pioneers the utilization of OAMMs for precise and versatile object manipulation through the coordination of independent twisting and grasping motions.
