Soft robots provide compliant object-machine interactions, but they exhibit insufficient material stability, which restricts them from working in harsh environments. Herein, we developed a class of soft robotic skins based on two-dimensional materials (2DMs) and gelatin hydrogels, featuring skin-like multifunctionality (stretchability, thermoregulation, threat protection, strain sensing). The 2DM-integrated hydrogel (2DM/H) enabled to execute designated missions the presence high levels heat...
In this work, the aerodynamic performance of beetle wing in free-forward flight was explored by a three-dimensional computational fluid dynamics (CFDs) simulation with measured kinematics. It is shown from CFD results that twist and camber variation, which represent flexibility, are most important when determining performance. Twisting significantly increased mean lift variation enhanced thrust while required power lower than case neither considered. Thus, comparison economy among rigid,...
The aim of this work is to provide an insight into the aerodynamic performance beetle during takeoff, which has been estimated in previous investigations. We employed a scaled-up electromechanical model flapping wing measure forces and three-dimensional flow structures on wing. ground effect unsteady were also characterized. dynamically scaled could replicate general stroke pattern beetle's hind kinematics takeoff flight. Two kinematic models have studied examine influences forces. In first...
Abstract Material properties and composite structures play key roles in tailoring the performance of soft robots. Unfortunately, current design fabrication approaches limit achievable complexity functionality these two categories hinder robot performance. Here, an approach that allows direct novel is presented. The process uses computational topology optimization to determine required 3D structure hyper‐elastic bodies. using all‐in‐one workflow with resilient silicone polymers enables...
Over the last decades, there has been great interest in understanding aerodynamics of flapping flight and development wing Micro Air Vehicles (FWMAVs). The camber deformation twisting demonstrated quantitatively a number insects, but making artificial wings that mimic those features is challenge. This paper reports characterization can reproduce deformations. By replacing elastic material at root vein, vein would bend upward inward generating an angle attack, camber, deformations while was...
Neuronal stimulation is an intricate part of understanding insect flight behavior and control itself. In this study, we investigated the effects electrical pulses applied to brain basalar muscle rhinoceros beetle (Trypoxylus dichotomus). To understand specific neuronal mechanisms, responses beetle, four electrodes were implanted into two optic lobes, brain's central complex ventral nerve cord in posterior pronotum. We demonstrated initiation, turning cessation by stimulating brain. The...
In this paper, we measure unsteady forces and visualize 3D vortices around a beetle-like flapping wing model in hovering flight by experiment numerical simulation. The measurement of flow patterns the were conducted using dynamically scaled mineral-oil tank. kinematics directly derived from real beetle. structures captured air bubble visualization while measured sensor attached at base. comparison, size topology spiral leading edge vortex, trailing vortex tip are well matched experimental...
Batoids use their large pectoral fins to achieve unique maneuverability and propulsive performance. In this work, the design, fabrication characterization a soft batoid-like robot is presented. The designed mimic un-dulatory rajiform locomotion. design under-actuated, simple robust well suited for performance experiments thanks its full autonomy, long battery life, wireless recharging capabilities. has 180mm body length, maximum flapping amplitude of 60deg, reaches peak speed 0.93 length per...
The development of flapping wing micro air vehicles (MAVs) have yielded remarkable progress over the last decades. Achieving high component stiffness is often in conflict with low weight requirement, which highly desirable for longer flight time and higher payload. Moreover, vibration originated predominantly from wings, gears frame excitations, compromises MAV's stability fatigue life. In order to improve vehicle's efficiency performance, optimization these various parameters necessary....
Although, a tremendous effort has been put forth to mimic flapping flights, MAV-inspired wing are unable perform take off flight and it seems be challenging topic for researchers. Taking into consideration of the currently driving system such as actuator, battery complexity link mechanism; it is quite difficult fabricate MAV adopting both principles jumping mechanism in flight. Understanding non-jumping take-off flying animal therefore necessary development model which can off. In this...
During recent decades, the understanding of aerodynamic flapping flight has been paid much attention by studying two modes, namely hovering and forward flight. However, there not on investigation characteristics during take-off an insect. In previous study, we found that Rhinoceros beetle, Trypoxylusdichotomus , takes off without jumping, which is uncommon for other this built a scale-up electromechanical model wing investigated fludi flow around beetle's model. It noted effect ground...
