Lumped Drag Model Identification and Real-Time External Force Detection for Rotary-Wing Micro Aerial Vehicles
Alcherio Martinoli, Lucas Cédric Wälti
This work focuses on understanding and identifying the drag forces applied to a rotary-wing Micro Aerial Vehicle (MAV). We propose a lumped drag model that concisely describes the aerodynamical forces the MAV is subject to, with a minimal set of parameters ...
2024Intelligent plantar pressure offloading for the prevention of diabetic foot ulcers and amputations
Yves Perriard, Yoan René Cyrille Civet, Christian Köchli, Sofia Lydia Ntella, Kenny Jeanmonod, Bhawnath Tiwari
The high prevalence of lower extremity ulceration and amputation in people with diabetes is strongly linked to difficulties in achieving and maintaining a reduction of high plantar pressures (PPs) which remains an important risk factor. The effectiveness o ...
2023Predicting unsteady flow separation in response to a flow disturbance
Karen Ann J Mulleners, Julien Dominique Claude Deparday, Sabrina Henne, Guosheng He
We present here a summary of the activities and results of dynamically stalling airfoils from the UNFoLD lab at EPFL that have been presented at the meetings of the NATO AVT-282 discussion group on Unsteady aerodynamic response of rigid wings in gust encou ...
American Institute of Aeronautics and Astronautics, Inc2020Biomechanical Properties and Resistance to Uprooting of Laboratory‐Scale Wood Logs
Wood dynamics affects riparian ecosystem functioning and river morphology. The spatial and temporal dynamics of wood pieces in river corridors, in particular of deposited rejuvenated wood logs, depend on their biomechanical properties and resistance to upr ...
AGU2020Delicate yet strong: characterizing the electro-adhesion lifting force with a soft gripper
Herbert Shea, Jun Shintake, Vito Cacucciolo
Compliant grippers are one of the most promising soft robotic devices for industrial tasks. Soft grippers dramatically simplify grasping control because the gripper automatically conforms to the object's shape. A common limitation of soft structures is tha ...
IEEE2019Hydrodynamic loading of perforated disks in creeping flows
François Gallaire, Pedro Miguel Nunes Pereira de Almeida Reis, Lorenzo Siconolfi, Matteo Pezzulla
We present results from an experimental investigation of a viscous fluid driven through and around porous disks at low and moderate Reynolds number conditions: Re = O(10(-4)-10(-3)) and Re = O(1-10). Specifically, we quantify the hydrodynamic drag that the ...
AMER PHYSICAL SOC2019Performance enhancement of downwind sails due to leading edge flapping: A wind tunnel investigation
Julien Dominique Claude Deparday
This work presents a wind tunnel experimental study on the effect of the leading edge flapping on the aerodynamic performance of a spinnaker. Four J80-class spinnaker models, combining two different assembling structures (panel layout) and two different sa ...
PERGAMON-ELSEVIER SCIENCE LTD2018Tack and deformation based sensorised gripping using conductive hot melt adhesive
The development of a universal method for grasping objects of varying morphology, material and size in unstructured environments remains an unsolved challenge. There is no one 'universal' solution which can function with low positional precision, can grasp ...
Institute of Electrical and Electronics Engineers Inc.2018Change in snow distribution patterns over an Antarctic ice floe following a snow storm event
Michael Lehning, Katherine Colby Leonard, Ernesto Trujillo Gomez
Sea ice, snow and atmosphere interactions are major drivers of the spatial distribution of snow over sea ice in polar regions. Here, we quantify changes caused by a snow storm in the spatial distribution of snow over an Antarctic ice floe at resolutions of ...
