Despite having achieved unconstrained stable flight, the insect-scale flapping-wing robot is still tethered for power and control. Towards the goal of operating a biologically-inspired robot autonomously outside of laboratory conditions. In this paper, we simulate outdoor disturbances in the laboratory setting and investigate the effects of wind gusts on the flight dynamics of a millimeter-scale flapping...
Inspired by the aerial prowess of flying insects, we demonstrate that their robotic counterpart, an insect-scale flapping-wing robot, can mimic an aggressive maneuver seen in natural fliers — landing on a vertical wall. Such acrobatic movement differs from simple lateral maneuvers or hover, and therefore requires additional considerations in the control strategy. Magnetic force was chosen to enable...
The methods derived from Maxwell's equations can be applied to simulate very fast surge situation with specific geometry structure and compute its current distribution. The common methods are the finite difference time domain (FDTD) method, the method of moments (MoM) and so on. This paper shows a method of thin wire representation using the Antenna Design Framework Electromagnetic Satellite (ADF-EMS)...
This paper introduces the structure and operational mechanism of Modular Multilevel Converter-High Voltage Direct Current (MMC-HVDC) and the mathematical model for the MMC-HVDC system in d-q synchronous reference frame is developed. When supplying power to passive networks, the MMC-HVDC controller at the passive network side, which contains a novel inner fast current loop and an outer voltage loop,...
An innovative solution to the lexical post processing of handwritten Pitman's shorthand, denoted as the Bayesian Network (BN) based transcription is discussed along with experimental results. Unlike the conventional phonetic based transliteration approach, the paper presents a novel primitive based transcription method along with the creation of a new machine readable Pitman's shorthand lexicon. The...
Based on the electromagnetic interaction of the peripheral field between two solenoids, a new electromagnetic mechanism is proposed with preferable merits of simple structure, easy optimisation and high controllability. A spatial interaction coefficient is specifically defined to describe the electromagnetic coupling scenario between the moving and the fixed coils constituting the mechanism, which...
