This paper presents development and performance analysis of a sensor node including accelerometer, temperature and humidity sensors for wireless sensor network (WSN) system intended for structural health monitoring (SHM) application. The developed prototype integrates software and hardware based on ARM controller, having excellent processing capability in terms of increased on board RAM and better power management facility. Data from sensor nodes are reliably transmitted to the base station, i.e. sink placed at a distance of about 30m. The system is verified using accelerometer data received at the base station through Fast Fourier Transform and found equivalent with that of a standard vibration data logger. Accelerometer data has also been explored in time-frequency domain using wavelet transform. The study also points out the best wavelet basis in the parlance of low frequency SHM applications.

AIP Conference Proceedings 2017年第1期1883卷

作者： Mohamad Fauzi Zakaria Tan Jiah Soon Munzilah Md Rohani 1Advanced Mechatronics Research Group (ADMIRE) Department of Mechatronics and Robotics Engineering Faculty of Electrical and Electronic Engineering Universiti Tun Hussein Onn Malaysia (UTHM) 864000 Batu Pahat Johor Malaysia 2Smart Driving Research Centre (SDRC) Faculty of Civil and Environmental Engineering Universiti Tun Hussein Onn Malaysia (UTHM) 864000 Batu Pahat Johor Malaysia

Recently, several bus accidents happened because of bus driver’s behavior. In fact, there is no dedicated tool for assisting them to drive safely. This project gives solutions to this by assisting the driver, according to the speed and acceleration of the bus. These data are collected by using a motion processing unit (MPU-6050) and a global positioning system (GPS) and then indicate the driving mode status on the LEDs. All data and status are recorded in a secure digital (SD) card for the authority or the bus company to analyze the driving behavior of a bus driver. This system has been successfully developed and tested in two different areas which includes the UTHM main campus and the road from Parit Raja to Batu Pahat.

Semi-virtual Plant for the Modelling, Control and Supervision of batch-processes. An example of a greenhouse irrigation system

引用

IFAC-PapersOnLine 2015年第29期48卷 123-128页

作者： Rodríguez, F. Castilla, M. Sánchez, J.A. Pawlowski, A. Department of Computer Science Automatic Control Robotics and Mechatronics Research Group University of Almería Agrifood Campus of International Excellence CeiA3 Spain Department of Computer Science and Automatic Control ETSII UNED Madrid Spain

In this work, a hardware-software architecture for control engineering education is proposed and a case of study regarding a greenhouse irrigation virtual process has been implemented. This specific process is especially useful for subjects related to industrial automation, since it is characterized by mixed dynamics (continuous/discrete) and can be controlled by a Programmable Logic Controller (PLC). In such a case, there is no need to access to the real process that is not always available for practical exercises. Moreover, the developed scheme eliminates the maintenance costs related to real process, being a very important advantage for academic institutions. The developed architecture for the industrial process simulation uses Labview, OPC, MODBUS, SolidWorks and Schneider Modicon M340 PLC for the control of virtual processes. The developed example is applied to the greenhouse fertirrigation control that enables the agricultural engineering students to design the irrigation control system. The control strategy is implemented on the PLC which interacts with the virtual process by carrying out the necessary actions in order to control the appropriate variables of the process. © 2015, IFAC (International Federation of Automatic Control) Hosting by Elsevier Ltd.

IOP Conference Series: Materials Science and Engineering 2016年第1期147卷

作者： I Doroftei F Adascalitei D Lefeber B Vanderborght I A Doroftei Mechanical Engineering Mechatronics and Robotics Department 'Gheorghe Asachi' Technical University of Iasi Iasi Romania Robotics and MultiBody Mechanics Research Group Vrije Universiteit Brussels Brusells Belgium

The purpose of this study is to present the preliminary steps in facial expressions recognition with a new version of an expressive social robotic head. So, in a first phase, our main goal was to reach a minimum level of emotional expressiveness in order to obtain nonverbal communication between the robot and human by building six basic facial expressions. To evaluate the facial expressions, the robot was used in some preliminary user studies, among children and adults.

The concept of a mechatronic bird has been developed by researchers over the years, to mimic the flight patterns of birds in nature. The developed mechatronics bird (MechaBird) described in this paper, explains the integration of the mechanical, electronic and software engineering that allows for the future evaluation of flight characteristics of a semi-autonomous, mechatronics bird, when adjustments are made to it that might have an effect on the efficiency of the system. The mechanical design and construction is explained with the results obtained of controlled flight motion tests.

In general, human beings receive most part of information through eyesight. Therefore, light is an essential element which allows people to distinguish the shape, colour and perspective of the environment around them. Moreover, energy efficiency in buildings is a problem that is being widely analysed since energy consumption inside them represents approximately 40% of total world energy consumption. In addition, illumination supposes around 20% of total energy consumption in houses and between 40% and 70% in shops and offices. This paper presents a fuzzy logic controller which allows maintaining visual comfort inside a meeting-room through an efficient use of both natural and artificial lights. In order to probe the effectiveness of the proposed control system, suitable real results obtained in a meeting-room of the CIESOL bioclimatic building are included and commented. © 2015 IEEE.

Microanastomosis is a microsurgical gesture that involves suturing two very small blood vessels together. This gesture is used in many operations such as avulsed member auto-grafting, pediatric surgery, reconstructive surgery - including breast reconstruction by free flap. When vessels have diameters smaller than one millimeter, hand tremors make movements difficult to control. This paper introduces our preliminary steps towards robotic assistance for helping surgeons to perform microanastomosis in optimal conditions, in order to increase gesture quality and reliability even on smaller diameters. A general needs assessment and an experimental motion analysis were performed to define the requirements of the robot. Geometric parameters of the kinematic structure were then optimized to fulfill specific objectives. A prototype of the robot is currently being designed and built in order to providing a sufficient increase in accuracy without prolonging the duration of the procedure.

In this paper we present a framework and a method for sense and avoid to be used with unmanned areial systems (UAS). The framework is an essential part to develop and validate the sense and avoidance algorithms. It is implemented and used for simulation and on a real system by using a common interface. The avoidance method in this paper is based on the fact that the intruder vehicle has certain limitations in turn rate and acceleration or deceleration. This is used to define the geometry of the threat zone for every intruder. In comparison to other geometry based algorithms the presented method uses the abilities (type) of the intruding aircraft and its current state. Diverse scenarios have been simulated successfully in that framework and code for the real system was generated and implemented.
