As a typical representative of amphibians, sea turtles can not only crawl on land but also have excellent underwater movement ability, which is an important source of inspiration for amphibious bionic robots. However, due to a lack of high-performance soft actuators, suitable bionic structure designs, and effective control methods, most of the current bionic turtle robots actuated by smart materials can only demonstrate movement in a single medium (e.g., swimming in water or crawling on land). Here, an amphibious turtle robot actuated by bionic muscles that can achieve effective movements in two media was designed. To enhance the amphibious ability of the turtle robot, a cylindrical dielectric elastomer actuator that can adapt to a variety of environments is designed with a maximum bidirectional deformation (±65°) and a high output force (∼80 mN). By optimizing the motion trajectory of the fins and programming the phase control of multiple bionic muscles, the robot's maximum swimming speed reaches 0.4 BL/s. In addition, the robot can realize different motion modes, such as forward, backward, lateral movement, turning, and crawling. Finally, the high mobility and environmental adaptability of the turtle robot are demonstrated in an L-shaped swimming passage and in two mediums (transition from land to water). This work not only improves the motion ability of bionic amphibious robots but is also useful for the motion control of other bionic robots with multiple actuators.","PeriodicalId":48685,"journal":{"name":"Soft Robotics","volume":"7 1","pages":""},"PeriodicalIF":7.9,"publicationDate":"2025-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145194841","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

One way to increase the number of digits in the end effector is through arrays of independent flexible structures, quantizing the gripper and increasing compliance. This work investigates what happens when we \"slice\" a Fin Ray soft gripper into an array of discrete fingers, called Fin-A-Rays. Fin-A-Rays are modular gripper systems that can be readily integrated into an off-the-shelf two-fingered parallel gripper. Here, between one and 24 Fin Ray fingers of width 2.5 mm to 60 mm are arranged side-by-side as a gripper. An analysis of the effects of finger width on gripper stiffness and object contact is presented via finite element analysis. The design space of Fin-A-Rays was studied via experiments and simulation, and a set of performance metrics for Fin-A-Rays was defined to understand the effects of \"slicing\" on grasping a set of objects. A design algorithm is also introduced to prearrange a Fin-A-Ray configuration based on an image of the object. The discretized compliance across an array of fingers in a Fin-A-Ray enables several novel behaviors during grasping, including finger splay and twisting. Results show that a balance between finger widths is required when slicing Fin-A-Rays, where algorithmically designed Fin-A-Rays showed higher average performance metrics than uniform configurations. Fin-A-Rays showed new capabilities, including multiobject grasping and in-hand manipulation. The passive morphological adaptability of Fin-A-Rays simplifies grasp planning, enabling delicate grasps for picking and packing complex shapes.","PeriodicalId":48685,"journal":{"name":"Soft Robotics","volume":"12 1","pages":""},"PeriodicalIF":7.9,"publicationDate":"2025-09-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145133926","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Although existing active woven structures have been successfully applied to actuators and sensors, the fabrication of intricate variable stiffness soft robots directly through weaving methods has consistently posed challenges. To address this issue, we draw inspiration from the Chinese knot technique and employ thin McKibben muscles to weave a variety of variable stiffness textiles, including a flexible spine, flexible skin, and a bistable structure, as well as innovative soft robots such as a soft crawling robot, a soft enclosed gripper, and a continuum module. Experimental results demonstrate that the variable stiffness range of the developed variable stiffness textiles exceeds 5.4 times that of the initial stiffness. Furthermore, we also experimentally demonstrate that the woven soft crawling robot (weighing 171 g) can achieve omnidirectional movement on an ferromagnetic surface at a maximum speed of 666.7 mm/min; the woven continuum module (weighing 49 g) can reduce the impact of external forces on the motion angle by over 65% by activating the high stiffness mode; the soft enclosed gripper (weighing 175 g) can lift objects weighing up to 14.7 kg, and the variable stiffness function can enhance its multi-directional bearing capacity by ∼3.3 times.

Elephants, as rare land animals, can manipulate all three states of matter using their lung-generated vacuum. In soft robotics, however, current vacuum generation relies on rigid components, and no single soft device effectively handles all states of matter. Traditional soft pumps and grippers are limited in scope: soft pumps provide continuous liquid flow but cannot directly manipulate solids, while grippers manage solids but are ineffective with liquids and gases. Inspired by lung functionality, we present a soft pressure-to-vacuum converter that provides precise control over the suction, holding, and release of solids, liquids, and gases through a single entry and exit point based on negative pressure. Through the selection of appropriate material properties and design variations, our soft device achieves vacuum levels up to -18 kPa, enabling intermittent control and sequential handling of various media without the need for additional components. We demonstrate diverse applications of our soft device, including artificial lungs, liquid blending, vacuum gripping, coffee preparation, and liquid-gas vaporization. This bioinspired device not only provides a safe and adaptable solution for vacuum generation but also addresses a critical gap in soft robotics, offering a multifunctional system capable of manipulating all states of matter.","PeriodicalId":48685,"journal":{"name":"Soft Robotics","volume":"19 1","pages":""},"PeriodicalIF":7.9,"publicationDate":"2025-09-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145031966","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Space environments are harsher and more varied than those on Earth; extreme temperature, pressure, and radiation may impact the performance and robustness of soft robots. Cryogenic temperatures on celestial bodies such as the Moon or Europa pose significant challenges to the flexibility and actuation performance of conventional soft systems. We present a soft robotic design methodology using novel metallic-based soft robotic structures specifically tailored to extreme space environments. Structures are presented as tunable, reconfigurable modules for soft systems. Module behavior under compression is characterized while submerged in liquid nitrogen, and structural changes are investigated using scanning electron microscopy (SEM). The structures retained flexibility at -196 °C, with a limited 5% increase in peak stiffness over 100 cycles while maintaining a full range of motion. A soft robotic limb was constructed from these modules and demonstrated successful 2D manipulation and grasping of objects at -196 °C. SEM analysis showed no physical signs of microfracture or deformation after cryogenic cycling, indicating changes to the underlying grain structure consistent with properties observed in cold-working stainless steels at cryogenic temperatures in the literature. Our findings demonstrate that metallic soft robotic structures maintain flexibility and exhibit promising performance in cryogenic, analogue space environments. This metal-based cable structure design approach provides a foundation for the development of functional, robust, and reconfigurable soft robots capable of operating in extreme space environments.","PeriodicalId":48685,"journal":{"name":"Soft Robotics","volume":"31 1","pages":""},"PeriodicalIF":7.9,"publicationDate":"2025-09-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145031965","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The combined driving pressures also enable shape adaptation to expand or contract as required. The manufacturing process for the balloon-type anchoring unit is detailed, which realizes high diameter/length ratio. The mechanics model is established, describing the deformation of the anchoring unit. Anchoring experiments were conducted in phantoms, mimicking both straight and tapered lumens, and ex vivo tissues.

However, when operating in soft tubular environments, they face significant challenges. The inherent instability of these structures can impede a robot's locomotion, and their soft tissues might be damaged by the interaction with robots. This study proposes a real-time stiffness perception system in soft tubular environments (e.g., colonic lumen) based on the earthworm-like movement to realize locomotion and detection simultaneously. The proposed soft robot features a central actuator (CA) for axial elongation and contraction, along with two auxiliary anchoring actuators positioned at the front and rear ends (FAA and RAA) to prevent backward slippage during locomotion. Notably, FAA is equipped with a perception mechanism capable of detecting the stiffness of the tubular environment through its interaction during inflation. The analytical modeling for CA's axial elongation, as well as the interaction between FAA and the surrounding tubular environment, has been developed and validated through experimental studies. Furthermore, the overall evaluation is conducted in two distinct tubes with: (1) uniform wall thickness but varied elastic moduli and (2) uniform elastic modulus but varied wall thicknesses. The successful locomotion and accurate perception confirm the capability and efficiency of the robot. In conclusion, the proposed robot system exhibits promising applications for locomotion and simultaneous stiffness detection in medical diagnostics and other fields where simultaneous locomotion and stiffness detection are crucial.","PeriodicalId":48685,"journal":{"name":"Soft Robotics","volume":"24 1","pages":""},"PeriodicalIF":7.9,"publicationDate":"2025-07-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144664187","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

One method of actuation, thermally driven liquid-to-vapor phase change heat engines, is particularly compelling due to its high forces, large strokes, and relative simplicity. However, this form of actuation suffers from a very low efficiency, making its impact for practical applications limited. Here we apply thermodynamic analysis to these phase-change actuators to identify major inefficiencies and offer three key insights that soft roboticists can leverage to improve efficiency: (1) maximize the ratio of input power to heat loss, (2) operate at an intermediate temperature, and (3) maximize volumetric expansion. We confirm the validity of these insights via benchtop experiments and show efficiencies nearly two orders of magnitude higher than previously reported. We demonstrate the usefulness of these insights by applying them to the design and construction of a compliant roller powered directly by sunlight and capable of rolling every 16 s. Our results guide the design of more efficient phase-change actuators for soft robots and more generally, demonstrate the potential of applying thermodynamic analysis to improve the efficiency of soft actuators.","PeriodicalId":48685,"journal":{"name":"Soft Robotics","volume":"48 1","pages":""},"PeriodicalIF":7.9,"publicationDate":"2025-07-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144547750","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, we present a 10-bar soft spherical tensegrity robot based on dodecahedron tensegrity (TR-10) with multiple movement gaits. It can generate a rolling motion by actively changing the length of the internal drive module, and the MATLAB dynamic model is established for simulation. The multi-objective optimization method is used to obtain the driving strategies for various basic gaits of the TR-10. The generated movement paths, formed by combining gaits, can fully cover the map. At the same time, the method for determining the rolling axis is proposed, which can enable the robot to roll to the target point along the optimal path. Finally, we fabricated the TR-10 prototype capable of a wireless-controlled rolling motion. By comparing the simulation and experimental results of the basic gaits and movement paths, the effectiveness of the proposed method is verified. In addition, we also compare it with the classical 6-bar 24-cable tensegrity robot, and the results show that our proposed TR-10 can complete different paths with shorter distances and smaller offsets.","PeriodicalId":48685,"journal":{"name":"Soft Robotics","volume":"57 1","pages":""},"PeriodicalIF":7.9,"publicationDate":"2025-05-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144146192","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
