The shape morphing is enabled by an innovative structure driven by an electrical actuation system that uses linear ultrasonic motors (LUSM) with compliant runners, enabling a full control of multiple degrees of freedom. The compliant runners also serve as structural components that carry the aerodynamic load and maintain a smooth skin curvature. The morphing structure with compliant truss is shown to exhibit a satisfactory flexibility and loading capacity in both numerical simulations and static loading tests. 😎 This design is capable of providing a pitching moment control independent of lift and higher L/D ratios within a wider range of angle of attack. Such multiple morphing configurations could expand the flight envelope of future unmanned aerial 2 vehicles. A small prototype was built to illustrate the concept but as no off-the-shelf LUSMs can be integrated into this bench top model, two servos are employed as actuators providing two controlled degrees of freedom. 🏆 Adam Harms Jenny Dempsey Katie Antal #composites #composite #compósitos #compositematerials #materialsengineering #fibers #lightweight #reinforcedplastics

Representing grandaliro often brings amusing moments, especially when explaining why I'm organizing the VýťahConf. - Space Industry conference. I try to convey that space exploration could be as transformative as the advent of mass internet, but I can see that not everyone is convinced. To demonstrate the potential, here is a presentation by Raphael Roettgen, CFA, an investor in Prometheus Life Technologies, a company working on 3D printing human tissue in low gravity (yes, in space!). This is a prime example of how today's seemingly insurmountable problems might become laughable in the future. Enjoy. https://lnkd.in/ebMDsq3i

Intuitive Machines lands on the Moon with the help of a crucial engine component made using Sciaky, Inc.'s EBAM technology. The part itself is the upper section of the main engine nozzle, which provides the main source of thrust for descent. Sciaky produced two additional upper nozzle sections, which were provided to Intuitive Machines for testing. Let's watch this space! #3dprinting #additivemanufacturing #aerospace #moonlanding #technology

💡 #Highcitedpaper #Beihang University #NorthwesternPolytechnicalUniversity 🌊 Title: Design and Experimental Research on a Bionic Robot Fish with Tri-Dimensional Soft Pectoral Fins Inspired by Cownose Ray 🔑 Keywords: #roboticfish; #kinematicmodel; high-fidelity #geometricmodel; #bionicpropellingmechanism; #3D soft pectoral fin 🔗 paper link: https://lnkd.in/gsSHPcdd 📜 Abstract： Bionic propulsion has advantages over traditional blade propellers, such as efficiency and noise control. Existing research on ray-inspired robot fish has mainly focused on a single type of pectoral fin as bionic propeller, which only performed well in terms of pure speed or maneuverability. Rarely has the performance of different fin types been compared on the same platform to find an optimal solution. In this paper, a modularized robot fish with high-fidelity biomimetic pectoral fins and novel multi-DOF propelling mechanism is presented. A kinematic model of the pectoral fin based on motion analysis of a cownose ray is introduced as guidance for the propelling mechanism design. A high-fidelity parametric geo-model is established and evaluated based on statistical data. The design and fabrication process of the 3D soft bionic fins, as well as the robot platform, is also elaborated. Through experiments comparing the performance of different fin types constructed with different materials and approaches, it was found that the new soft fins made of silicon rubber have better performance than traditional fins constructed with a flexible inner skeleton and a permeable outer skin as a result of better 3D profile preservation and hydrodynamic force interaction. The robot ray prototype also acquires a better combination of high speed and maneuverability compared to results of previous research.

I'm thrilled to present the results of my thesis titled "Enhancing Rover Versatility on Mixed Terrain" under the supervision of Salah Sukkarieh. My research focused on developing novel mobility solutions for rovers in space exploration, addressing key challenges faced on varied extraterrestrial terrains. Key Highlights: 1. Shape-Shifting Wheel: Perhaps the most groundbreaking aspect of my thesis, I've designed a wheel that can transform from a conventional circular wheel to a triangular tracked configuration. This design addresses critical issues of traction and sinkage in loose terrains like regolith, while optimizing power consumption – a pivotal factor in space missions. 2. 3D Printed Honeycomb Wheel: Innovatively designed using biomechanical principles, this wheel features a honeycomb structure for exceptional impact dampening – crucial for mitigating forces during Sky Crane landings on planetary surfaces. Its adaptability across diverse terrains, from rocky outcrops to steep inclines, marks a significant advancement in rover wheel technology. The development process involved rigorous iterative refinements, ensuring each design iteration improved upon the last in terms of structural integrity, energy efficiency, and integration with rover systems. The shape-shifting mechanism, in particular, underwent extensive prototyping to perfect the balance between mobility and power usage. The practical applications of these innovations extend beyond space exploration, potentially revolutionizing vehicle design in challenging terrestrial environments. I extend my heartfelt gratitude to Salah Sukkarieh, the Australian Centre for Robotics team, the University of Sydney, and everyone involved in this project. #SpaceExploration #RoverMobility #EngineeringInnovation #3DPrinting #Robotics #ThesisJourney #UniversityofSydney #ACFR #USyd

Our pre-print titled "DisMech: A Discrete Differential Geometry-based Physical Simulator for Soft Robots and Structures" is available on arXiv. Link to the pre-print: https://lnkd.in/gmEXHe5n This work was done in collaboration with Prof. Andrew Sabelhaus' group at Boston University. The paper introduces DisMech, a simulation environment designed to model the dynamic motions of rod-like soft continuum robots and structures with high accuracy and speed, overcoming limitations in existing robotics simulation frameworks. DisMech employs a fully implicit discrete differential geometry-based physics solver with efficient contact handling, and its gradient descent approach facilitates the mapping of hardware robot prototypes' motions to control inputs, demonstrating significant speed improvements and high physical accuracy in soft robot simulations.
