“…The application of a gust mitigation system (GMS) in flapping wing UAVs served a purpose similar to the covert feathers, helping mitigate gusts of winds only while facing turbulence, and remained integrated with the entire wing at all other times to maintain the wing profile. A Bat's wing possesses a very articulated musculoskeletal system, which assists them with multiple degrees of freedom, in addition to a compact and lightweight mechanism [75][76]. Mimicking this behaviour, Figure22 depicts an arm wing structure that was modelled and analysed.…”

The field of bio-inspired design has tremendously transitioned into newer automated methods, yet there are methods being discovered which can elucidate underlying principles in design, materials, and manufacturing. Bio-inspired design aims to translate knowledge from the natural world to the current trends in industry. The recent growth in additive manufacturing (AM)methods has fueled the tremendous growth of bio-inspired products. It has enabled the production of intricate and complicated features notably used in the aerospace industry. Numerous methodologies were adopted to analyse the process of bio-inspired material selection, manufacturing methods, design, and applications. In the current review, different approaches are implemented to utilize bio-inspired designs that have revolutionized the aerospace industry, focusing on AM methods.

“…This concept has triggered product innovation in many ways. It allows to obtain specific mechanical properties and performances, through the emulation of material structures (Fischer et al, 2010), but also systems and mechanisms (Sihite et al, 2020). It can be thus a means to explore both new material designs (Ren et al, 2019) and various aesthetic and functional features, as in the case of furniture (Tavsan and Sonmez, 2015) and architectural design (Oxman, 2010) or innovative wearable solutions (Babaee et al, 2020).…”

Bioinspired Computational Design: A Case Study on a 3d-Printed Lamp Based on the Physalis Alkekengi

Nature has always been a source of inspiration for designers and engineers, through the imitation of biological patterns and structures. This emulating and creative process is nowadays supported by technologies and tools as additive manufacturing and computational design. This paper describes the design and prototyping of a lamp inspired by a plant called Physalis Alkekengi, known as Chinese Lantern. We present the development of an algorithm, based on a computational model from literature, to realize the 2D pattern and leaves. They were then 3D printed to create the structure of the lamp and obtain an aesthetical and symbolic shading effect.

Landing on vertical surfaces in challenging environments is a critical ability for multimodal robots—it allows the robot to hold position above the ground without expending energy to hover. Asian flat‐tailed geckos (Hemidactylus platyurus) are observed to glide and perch on vertical surfaces by relying on their tail and body morphology, potentially reducing the control effort to perch. This novel perching mechanism using a bioinspired physical model is discussed and its tail and body parameters to determine their influence on perching success and the kinematics of the gecko's dynamic landing maneuver are adjusted. Perching performance is evaluated by changing the model's torso and tail stiffness. Combining a compliant torso and stiff tail enables the model to passively perch on a vertical substrate with a success rate >90%, compared with ≈10% without a tail attached. A compliant torso is necessary to absorb the in‐flight kinetic energy and accommodate the uncertainties in approach conditions. Similar to the gecko's perching strategy, the stiff tail pushes against the substrate, preventing the model from falling backward head over heels. These findings highlight the critical role of tail and material stiffness for perching and provide a simplified mechanism to impart perching capabilities in robots.
