They need to know, for example, when their flight is disturbed by an eddy in turbulent air or by an imperfectly executed wing beat… 

P2E-7 A Novel AT-Cut Gyroscope, Its Analysis and Design

A novel AT-cut quartz vibratory gyroscope with a sensitivity to angular velocity of 1.3 mV/deg/s was presented. The gyroscope employed the thickness shear mode as the driving mode and the flexure

Biologically inspired, haltere, angular-rate sensors for micro-autonomous systems

The successful fabrication of a micro-angular rate sensor represents a substantial breakthrough and is an enabling technology for a number of Army applications, including micro air vehicles (MAVs).

Haltere Mechanics and Mechanical Logic for Micro-Electro-Mechanical Systems (MEMS) Scale Bio-inspired Navigation Sensors

Abstract : Small autonomous aerial systems require the ability to detect roll, pitch, and yaw to enable stable flight. Existing inertial measurement units (IMUs) are incapable of accurately measuring

Gyroscope-like molecules consisting of PdX₂/PtX₂ rotators within three-spoke dibridgehead diphosphine stators: syntheses, substitution reactions, structures, and dynamic properties.

Threefold intramolecular ring-closing metatheses of trans-[MCl2(P{(CH2)(m)CH=CH2}3)2] are effected with Grubbs' catalyst and NMR data show that the MX2 moieties rapidly rotate within the diphosphine cage on the NMR timescale, even at -120 °C.

Stimuli-responsive anisotropic actuation of melem-formaldehyde polymer

In nature, organisms control their deformation and locomotion through multi-functional synergy in response to environmental changes. Nowadays, most synthetic biomaterial systems are capable of

Derivative kinematics in relatively rotating coordinate frames: investigation on the Razi acceleration

The Razi acceleration has been discovered as a new acceleration term that appears due to relative motion of multiple moving reference frames. When Newton's laws of motion are transformed between a

Anisotropic bilayer hydrogels with synergistic photochromism behaviors for light-controlled actuators

Smart hydrogels have attracted widespread attention and have displayed comprehensive applications in many fields. The development of a novel type of bilayer hydrogel with synergistic function of

From these considerations it is concluded that Coriolis forces play the major role in detecting body rotations.

The paper gives a detailed anatomical, dynamical and physiological analysis of the gyroscopic mechanism of the halteres of the higher Diptera. (1) A re-examination has been made of the structure of

Antennal Mechanosensors Mediate Flight Control in Moths

It is shown that mechanosensory input from the antennae serves a similar role during flight in hawk moths, which are four-winged insects, and plays a crucial role in maintaining flight stability of moths.

Strepsipteran forewings are haltere-like organs of equilibrium

It is shown for the first time conclusively that the specialized forewings in male Strepsiptera play the same role as halteres in flies, similar to vestibular organs of vertebrates, crabs, and cephalopods.

Biomechanical aspects of the evolution of semicircular duct systems

The three-duct theory gives physical evidence for the possible evolution of the semicircular duct system and it is proposed that the early vertebrates already possessed a three- duct system comparable to that of recent Tetrapoda.
