There are a few corrections for <xref ref-type="bibr" rid="ref1">[1]</xref> that are presented here. Some readers noticed the coordinate of the source in <xref ref-type="bibr" rid="ref1">[1, Fig. 1]</xref> should be described using the superscript, therefore, we would like correct <xref rid="fig1" ref-type="fig">Fig...
In the compact micro-grasping system, the combination of precisely orthogonal movement transformation, displacement amplification and simple structure is important. The typical solution of the combination issue requires bidirectional symmetric input forces/displacements. However, under a certain driving condition, numerous actuators used in micro-manipulation only supply unidirectional input froce/displacement...
Flexure-based mechanisms like compliant actuation system embed complex dynamics which will reduces the control bandwidth and limit their dynamic positioning precision. This paper presents a theoretical model of a leaf flexure hinge with damping layers using strain energy method and Kelvin damping model. The free vibration signals of the hinge in three different damping configurations are measured...
In this paper, we investigate the near field Orbital Angular Momentum (OAM) using the rigorous numerical methods. To model the communication channel of the OAM system, we derived a rigorous channel matrix for the near field transmitter/receiver system. This channel matrix is composed of the admittance matrices of the system. To obtain these admittance matrices, the integral equation method is employed...
A novel biped robot that can climb poles, trusses and trees for high-rise missions has been recently developed. Consisting of an arm as the main body and two grippers mounted at the two ends as the end-effectors, the robot has both climbing function and manipulating function. One key issue with the robot is that its gripper must grasp the object firmly to support the whole robot when it performs climbing...
Biomimetic flapping-wing robot is a new type of miniature air vehicle mimicking birds or insects to fly, with many unique advantages that traditional fixed-wing and rotary-wing aircrafts do not possess. Unsteady aerodynamics at low Reynolds number is the main theory applied to the flight analysis of such air vehicles with flapping-wings, and it is still a big challenge. Various models have recently...
In this paper, a method is presented for the dynamic modeling of parallel robots with flexible links and rigid platform. For a 3-RRR planar parallel manipulator, it is divided as three flexible sub-structures and a rigid moving platform. Because flexible sub-structures are connected by the rigid platform, the geometrical constraint relationship between them represent the influences each other. It...
