Measurement of standing balance ability by a wire driven parallel mechanism
Falls are a major reason for elderly people to require nursing care. Prevention of falls requires evaluation of standing balance ability of human. Thus various measurements were performed and the relation between the results and occurrence of falls was ...

Probing the local dynamics of periodic orbits by the generalized alignment index (GALI) method
As originally formulated, the Generalized Alignment Index (GALI) method of chaos detection has so far been applied to distinguish quasiperiodic from chaotic motion in conservative nonlinear dynamical systems.

Impedance Controller Tuned by Particle Swarm Optimization for Robotic Arms
This paper presents an efficient and fast method for fine tuning the controller parameters of robot manipulators in constrained motion. The stability of the robotic system is proved using a Lyapunov‐based impedance approach whereas the optimal ...

RoboBat: Dynamics and Control of a Robotic Bat Flapping Flying Testbed [PDF]
This paper investigates the control of the phase difference in between three different motions of bat flight: pitching, mapping, and lead-lag. For active control, a robotic bat test bed capable of simulating different wing motions is used to test the ...

A Large-Stroke 3DOF Stage With Integrated Feedback in MEMS
In this paper, we design, fabricate, and validate a large-stroke 3-degree-of-freedom (DOF) positioning stage with integrated displacement sensors for feedback control in a single-mask microelectromechanical systems (MEMS) fabrication process. Three equal shuttles exactly define the position of the stage in x, y, and Rz.

Abstract Deep learning models for structural response estimation exhibit degraded performance when the training and input data characteristics differ, particularly because of noise. This study proposes an anti‐frequency long short‐term memory (AF‐LSTM) model designed to ensure a stable estimation regardless of noise conditions. The term “anti‐frequency”
