Research on frequency characteristic test method of servo mechanism based on schroeder phased harmonic signal [PDF]

open access: yesE3S Web of Conferences, 2019
The traditional frequency response test mainly adopts the sweep frequency sinusoid signal testing method, which has high accuracy, but takes a long time. This paper introduces the basic theory of the Schroeder Phased Harmonic Signal (SPHS) testing method.

A Thickness-Invariant Origami Robot With Integrated Actuation and Multimodal Locomotion. [PDF]

open access: yesAdv Sci (Weinh)
A thickness‐invariant variation on the Yoshimura origami pattern is used as the basis of a robot, allowing power, actuation, and control systems to be embedded within the thickened panels of the pattern. The robot uses multiple kinematic branches to achieve distinct modes of locomotion, such as walking, running, galloping, and turning. ABSTRACT Origami

Development of converted nearfield acoustic holography method (The verification by experiments using mechanical elements)

open access: yesNihon Kikai Gakkai ronbunshu, 2015
There are several types of sound localization methods. However, the almost methods are used for sound localization of middle frequency noise around 1kHz. In high frequency, the measurement of sound field needs huge load. Therefore the measurement of high

Visual servoing utilizing zoom mechanism [PDF]

open access: yesProceedings of 1995 IEEE International Conference on Robotics and Automation, 1998
A camera, which is used as an artificial vision in visual servoing control, often has a zoom mechanism. A zoom mechanism cannot realize fast motion while an arm mechanism can, and it has only one degree of freedom. On the other hand the arm mechanism cannot cover wide range of change of images while the zoom mechanism can.

Mechanism Analysis of Time-Dependent Characteristic of Dynamic Errors of Machine Tools

open access: yesMachines, 2022
The Dynamic Errors (DEs) of individual axes present Time-dependent Characteristics (TDCs) because the setpoints, as the input of the servo feed system, change in velocity, acceleration and jerk during the feed motion.
