SDR-4X is the latest prototype model which is a small humanoid type robot. We reported the outline of this robot last year. In this paper we discuss more about mechanical system which is important and original for a small biped entertainment robot which will be used in home environment. One technology is the design of actuators alignment in the body which enables dynamic motion performance. Ano...

There is an increasing demand for vehicles suitable for both on and off road driving characterized by superior comfort and handling performance. This is problematic formost suspension systems because there is a trade off balance between vibration reduction, suspension travel, actuator effort, road holding capability, as well as noise and fatigue requirements. Only in the UK every 11 min a car i...

1.1 Robot manipulators Robot manipulators are well-known as nonlinear systems including strong coupling between their dynamics (Craig, 1996). These characteristics, in company with: 1) structured uncertainties caused by model imprecision of link parameters, payload variation, etc., and 2) unstructured uncertainties produced by un-modeled dynamics –such as nonlinear friction and external disturb...

This paper develops an Intelligent Chair Tool (ICT) — a new chair-type human and machine interaction seating system powered by 36 intelligent pneumatic actuators. This tool can be used to facilitate investigation of chair shapes from spring and damping effects of seating and backrest surfaces. Each actuator used consists of five extensive elements of encoder, laser strip rod, pressure sensor, v...

The objective of current paper is 3D simulation of turbulent, developing flow and unsteady within a circular duct in presence of the body force vector persuaded by Dielectric barrier discharge (DBD) plasma actuator inside the surface of geometry for the first time. This article aims at investigating of applying plasma actuator to control separation with special arrangement of electrodes. For th...

In this paper, the problem of fault-tolerant control is investigated for turbofan engines with actuator faults. The controller involvement has repressed effects faults on controlled outputs engines, making difficult. To solve problem, internal gas-path data introduced to provide conducive fault information. Besides, useful property convolution neural network (CNN) explored and utilized in contr...
