A Deep Inverse-Mapping Model for a Flapping Robotic Wing
Hadar Sharvit, Raz Karl, Tsevi Beatus
In systems control, the dynamics of a system are governed by modulating its inputs to achieve a desired outcome. For example, to control the thrust of a quad-copter propeller the c…
Solving the thoracic inverse problem in the fruit fly
Arion Pons, Illy Perl, Omri Ben-Dov +2
In many insect species, the thoracic structure plays a crucial role in enabling flight. In the dipteran indirect flight mechanism, the thorax acts as a transmission link between th…
Work-loop techniques for optimising nonlinear forced oscillators
Arion Pons, Tsevi Beatus
Linear and nonlinear resonant states can be restrictive: they exist at particular discrete states in frequency and/or elasticity, under particular (e.g., simple-harmonic) waveforms…
Band-type resonance: non-discrete energetically-optimal resonant states
Arion Pons, Tsevi Beatus
Structural resonance involves the absorption of inertial loads by a tuned structural elasticity: a process playing a key role in a wide range of biological and technological system…
Distinct forms of resonant optimality within insect indirect flight motors
Arion Pons, Tsevi Beatus
Insect flight motors are extraordinary natural structures that operate efficiently at high frequencies. Structural resonance is thought to play a role in ensuring efficient motor o…
Conditions for energetically-optimal elasticity and their implications for biomimetic propulsion systems
Arion Pons, Tsevi Beatus
Minimising the energy consumption associated with periodic motion is a priority common to a wide range of technologies and organisms - among them, many species of flying insect, fo…
Pitch Perfect: How Fruit Flies Control their Body Pitch Angle
Samuel C. Whitehead, Tsevi Beatus, Luca Canale +1
Flapping insect flight is a complex and beautiful phenomenon that relies on fast, active control mechanisms to counter aerodynamic instability. To directly investigate how freely-f…
Roll Control in Fruit Flies
Tsevi Beatus, John M. Guckenheimer, Itai Cohen
Due to aerodynamic instabilities, stabilizing flapping flight requires ever-present fast corrective actions. Here we investigate how flies control body roll angle, their most susce…
Anomalous Microfluidic Phonons Induced by the Interplay of Hydrodynamic Screening and Incompressibility
Tsevi Beatus, Roy Bar-Ziv, Tsvi Tlusty
We investigate the acoustic normal modes ("phonons") of a 1D microfluidic droplet crystal at the crossover between 2D flow and confined 1D plug flow. The unusual phonon spectra of…
Phonons in a one-dimensional microfluidic crystal
Tsevi Beatus, Tsvi Tlusty, Roy Bar-Ziv
The development of a general theoretical framework for describing the behaviour of a crystal driven far from equilibrium has proved difficult1. Microfluidic crystals, formed by the…
