However, due to the limitations of underwater communication technologies, underwater robot swarms have lagged behind aerial and ground swarms in their development. This paper primarily explores the applications and advancements of swarm intelligence (SI) in multiple underwater robot swarms. Inspired by the behavior of animal swarms, researchers have translated this concept into the design and control strategies of underwater robot swarms. This approach draws on the self-organization, robustness, and adaptability inherent in collective behaviors, significantly enhancing the performance of underwater robot swarms. This paper provides a comprehensive review of the current research status of bio-inspired swarming of multiple underwater robots, including the design and classification of swarm underwater robots, SI algorithms and their applications in multiple underwater robots, and communication mechanisms for underwater robots.

However, accurately evaluating the adhesion performance of these materials remains a critical challenge. To bridge this gap, we experimentally investigate the detachment behavior of two representative BFA types: mushroom-shaped fibrillar adhesives and flat-shaped fibrillar adhesives. The experimental results reveal that the critical detachment force (i.e. pull-off force) is significantly influenced by preload, detachment velocity, and detachment angle. Unlike the monotonic effects observed for preload and velocity, the detachment angle exhibits a non-monotonic relationship with the pull-off force. Specifically, as the detachment angle increases from 0° to 90°, the pull-off force first decreases and then increases. Further experimental validation and numerical simulations indicate that the equivalent bending moment induced by the pull-off force modulates the critical detachment angle-a phenomenon not reported in the existing literature. In addition, the fracture mode transitions from bilateral to unilateral crack propagation as the detachment angle decreases. Simulation results further demonstrate that the detachment angle alters the stress distribution at the adhesive interface, thereby affecting the crack propagation mode. Based on these findings, an approximate pull-off force model for BFA specimens is developed using linear elastic fracture mechanics, which incorporates the effects of preload, detachment velocity, and detachment angle. Following parameter identification, the proposed model accurately predicts the pull-off force for various loading conditions.","PeriodicalId":55377,"journal":{"name":"Bioinspiration & Biomimetics","volume":" ","pages":""},"PeriodicalIF":3.1,"publicationDate":"2025-06-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144250895","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This review provides a comprehensive synthesis of the key biomechanisms associated with silent flight, including both historical perspectives and the latest experimental and computational findings. We also systematically classify and analyse current biomimetic applications in various engineering contexts-including aircraft noise reduction, wind turbine blade optimisation, and other industrial implementations-thereby establishing a clear mechanistic link between fundamental aeroacoustic principles and real-world engineering solutions. Finally, we discuss the key challenges and future directions in owl-inspired aeroacoustics, emphasising the integration of morphological adaptations, wing flexibility, and flight kinematics.

Through three-dimensional numerical simulations using an immersed boundary method at Reynolds number of 3000, we analyze the impact of varying Strouhal number (St = 0.2-0.35) and propulsive wavelength (λ∗= 1.0-1.2) on swimming performance. Our findings reveal two distinct wake patterns: a single-row structure at lower Strouhal numbers (St⩽0.25) and a double-row configuration at higher St (St⩾0.3). Increasing wavelength generally enhances thrust production by reducing both pressure and friction of drag components. Additionally, we identify critical vortex interactions between the front and hind flippers, with destructive interference occurring at lower St and constructive patterns emerging at higher St. Circulation analysis confirms stronger vortex formation at higher St andλ∗, particularly during the left stroke phase. These results provide novel insights into the hydrodynamic mechanisms underlying seal locomotion and contribute to our understanding of efficient aquatic propulsion systems.","PeriodicalId":55377,"journal":{"name":"Bioinspiration & Biomimetics","volume":" ","pages":""},"PeriodicalIF":3.1,"publicationDate":"2025-06-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144175897","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the noise emitted by UAVs remains a significant impediment to their widespread use even though in areas such as product delivery, they can be more environmentally friendly than traditional delivery methods. Nature has often been a source of inspiration for devices that are efficient and eco-friendly. In the current study, we leverage the previous work by Seoet al(2021Bioinsp. Biomim.16046019) on the aeroacoustics of flapping wing flight in mosquitoes and fruit flies to propose and examine a simple strategy for reducing the aeroacoustic noise from drone rotors. In particular, inspired by these insects, we explore how an increase in the planform area of the rotor could be used to reduce the rotation rate and the associated aeroacoustic noise from small-scale rotors. The study employs a sharp-interface immersed boundary solver for the flow simulations and the aeroacoustic sound is predicted by the Ffowcs Williams-Hawkings equation. Simulations indicate that the simple strategy of employing rotors with larger planform areas could lead not just to reduced aeroacoustic noise but improved power economy as well.","PeriodicalId":55377,"journal":{"name":"Bioinspiration & Biomimetics","volume":" ","pages":""},"PeriodicalIF":3.1,"publicationDate":"2025-06-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144183160","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

They offer benefits such as adjustable stiffness, back-drivability, and muscle failure tolerance but are difficult to model and control due to redundancies across task, joint, and muscle activation spaces, compounded by complex muscle dynamics and motion-dependent moment arms. Analytical methods require detailed system knowledge and lack scalability, while model-free approaches often rely on manual tuning and rarely exploit motor redundancy. This work introduces a model-free, biologically inspired kinematic controller based on reflex circuits that self-organise via Hebbian learning driven by Spontaneous Motor Activity (SMA). These circuits are then integrated to create a computationally inexpensive task-space controller, requiring minimal training and no analytical modelling. Simulations with six- and twelve-muscle models show that the interaction between reflex circuits, morphology, and gain modulation produces coordinated muscle synergies for human-like target reaching. Unlike previous control methods, it is easily scalable, can automatically handle unknown disturbances, and compensates for inaccessible muscles without re-training or manual intervention while maintaining high control accuracy.","PeriodicalId":55377,"journal":{"name":"Bioinspiration & Biomimetics","volume":" ","pages":""},"PeriodicalIF":3.1,"publicationDate":"2025-06-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144175839","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"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 reinforcement learning (RL) has been employed to generate insect-like gaits, the design of an appropriate reward function presents a challenge due to the probabilistic and continuous nature of gait transitions. This study utilized maximum entropy inverse RL to infer the reward function that governs stick insect gait selection, incorporating walking dynamic parameters-namely, velocity, direction, and acceleration-alongside antenna joint movements as state variables. By analyzing the inferred reward structures, we clarified the underlying principles that drive gait transitions and emphasized the role of sensory feedback in gait modulation. The efficacy of the inferred policies was validated through an assessment of their ability to reproduce expert trajectories, demonstrating that stick insect gaits can be learned from observable states during locomotion. Furthermore, interspecies variations and noncanonical gait patterns were examined, providing insights into the flexibility and adaptability of insect locomotion. This data-driven approach offers a biologically interpretable framework for gait modeling and contributes to bioinspired robotic design by facilitating adaptive control strategies for hexapod robots.","PeriodicalId":55377,"journal":{"name":"Bioinspiration & Biomimetics","volume":" ","pages":""},"PeriodicalIF":3.1,"publicationDate":"2025-06-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144129651","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
