HEPA FILTER MATERIAL LOAD DETECTION USING A MICROWAVE CAVITY SENSOR

A. Mason/ S. Wylie/ A. Thomas/ H. Keele/ A. Shaw/ A.I.Al- Shamma’a/ A. Mason/ S. Wylie/ A. Thomas/ H. Keele/ A. Shaw/ A.I.Al- Shamma’a

This paper presents a novel microwave cavity sensor application for the detection of HEPA filter particulate loading. The sensor resonates at 3.435GHz and 8.570GHz when empty, where the TM010 and TM020 modes dominate respectively. Experimental results show that the resonant frequency of the sensor shifts significantly when filters of different particulate loadings are presented to it. This is a significant finding, and means that the sensor could present an effective solution for determining the(..)

Kazuyuki Morioka/ Szilveszter Kovacs/ Joo-Ho Lee/ Peter Korondi

The intelligent environments, built upon many distributed sensors, are promising technology for ubiquitous interaction between robots and human beings. Especially, it is important to track target objects and get the positional information of them in such environments. This paper focuses on adapting camera selection for target tracking in multi-camera system. In this paper, a fuzzy automaton based camera selection method is introduced. In the proposed method, the camera selection decision is driv(..)

ANALYSIS OF TACTILE SLIPPAGE CONTROL ALGORITHM FOR ROBOTIC HAND PERFORMING GRASP-MOVE-TWIST
MOTIONS

Hanafiah Yussof/ Jiro Wada/ Masahiro Ohka

This paper presents an analysis result of grasp-move-and-twist motions of robotic hands equipped with optical three-axis tactile sensor to evaluate performance of a new control algorithm based on tactile slippage sensation. The optical three-axis tactile sensor is capable of defining normal and shear forces simultaneously. The proposed algorithm consists of robot arm and hand controls based on parameters of normal and shear force, and slippage detection. To improve performance during grasp, move(..)

A Spherical Haptic Interface with Unlimited Workspace

Yuichi Tsumaki/ Takeshi Ohgi/ Arata Niiyama

Over the last two decades, various haptic interfaces have been developed. However, their workspace has been mechanically restricted. This limited workspace reduces operationality, because operation should be suspended at the boundary. In this paper, to tackle this problem, a spherical haptic interface is developed, which utilizes a ball as an interface with the human. The ball is driven by three DC motors through omni wheels. Consequently, unlimited workspace is achieved for orientation. Further(..)

DUAL MODALITY TOMOGRAPHY SYSTEM USING OPTICAL AND ELECTRODYNAMIC SENSORS FOR TOMOGRAPHIC IMAGING SOLID FLOW

M. F. Rahmat/ S. Ibrahim/ M. M. Elmajri/ N. F. Mohammed/ M.D Isa

Process tomography is a technique to realize flow imaging in a process vessel or pipeline by using the sensor system. This technique involves the use of tomographic imaging methods to manipulate data from sensors in order to collect sufficient information about the flow in the pipeline. The overall aim of this paper is to investigate the benefits of dual modality (optical and electrodynamic) tomography system for the measurement of tomographic images of solids flow. This research will investigat(..)

USING LEGO MINDSTORMS NXT™ ROBOTICS KITS AS A SPECTROPHOTOMETRIC INSTRUMENT

Martin Kocanda/ Bryn M. Wilke/ David S. Ballantine

High-end spectrophotometric analytical instruments are typically employed in academic institutions and industrial research laboratories and are rarely available for experimenters or younger students. An affordable high-tech robotic product manufactured by Lego may be employed as a single-beam monochromatic light source, detector and display to demonstrate and investigate the Beer-Lambert law using solutions containing chromophores that absorb light in the 600 nm - 660 nm range. Using the materia(..)

W. Jatmiko/ W. Pambuko/ A. Febrian/ P. Mursanto/ A. Muis/ B. Kusumoputro/ K. Sekiyama/ T. Fukuda

A new algorithm based on Modified Particle Swarm Optimization (MPSO) that follows is a local gradient of a chemical concentration within a plume and follows the direction of the wind velocity is investigated. Moreover, the niche or parallel search characteristic is adopted on MPSO to solve the multi-peak and multi-source problem. When using parallel MPSO, subgroup of robot is introduced then each subgroup can locate the odor source. Unfortunately, there is a possibility that more that one subgro(..)

SELF-ORGANIZING URBAN TRAFFIC CONTROL ARCHITECTURE WITH SWARM-SELF ORGANIZING MAP IN JAKARTA: SIGNAL CONTROL SYSTEM AND SIMULATOR

W. Jatmiko/ A. Azurat/ Herry / A. Wibowo/ H. Marihot/ M. Wicaksana/ I. Takagawa/ K. Sekiyama/ T. Fukuda

Urban traffic control is the main factor that contributes to traffic jam. Approach in distributed Urban traffic control has been developed in several research, but the coordinating controller factor is basically a quite complicated task to tackle, because between intersection have dependency, so required a method of distributed control system capable for synchronizing between intersections. In this paper we present architecture of decentralized self-organizing traffic control with swarm-self org(..)

TWO METHODOLOGIES TOWARD ARTIFICIAL TACTILE AFFORDANCE SYSTEM IN ROBOTICS

M. Ohka/ N. Hoshikawa/ J. Wada/ H. B. Yussof

If the theory of affordance is applied to a robot, performing the whole process of recognition and planning is not always required in its computer. Since the tactile sensing of a robot is important to perform any task, we focus on tactile sensing and introduce a new concept called the artificial tactile affordance system (ATAS). Its basic idea is the implementation of a recurrent mechanism in which information obtained from the object and the behavior performed by the robot’s inducing the next b(..)

INVESTIGATION ON VELVET HAND ILLUSION USING PSYCHOPHYSICS AND FEM ANALYSIS

M. Ohka/ Y. Kawabe/ A. Chami/ R. Nader/ H. B. Yussof/ T. Miyaoka

In the velvet hand illusion (VHI), a person rubs his/her hands together on either side of wires strung through a frame, producing the sensation of rubbing a very smooth and soft surface like velvet. We investigate the VHI mechanism to obtain an effective hint for a new tactile display because such tactile illusions play a good role in deceiving the brain so that operators believe that a virtual sensation is real. To elucidate the VHI mechanism, we propose two approaches: one uses psychophysics (..)

RELIABLE DATA BROADCAST FOR ZIGBEE WIRELESS SENSOR NETWORKS

Tien-Wen Sung/ Ting-Ting Wu/ Chu-Sing Yang/ Yueh-Min Huang

As we know, the data transmission in the wireless networks is more unreliable than it is in the wired network environment. Although the virtual carrier sensing scheme can be used in the wireless unicast transmission, the multicast and broadcast still not utilize the acknowledgement mechanism for reliable transmission. This is due to the acknowledgement packets of broadcast transmission will cause much higher communication traffic and overhead. Since reliable data broadcast is critical and requir(..)

REAL-TIME PATH PLANNING TRACING OF DEFORMABLE OBJECT BY ROBOT

Khairul Salleh Mohamed Sahari/ Hiroaki Seki/ Yoshitsugu Kamiya/ Masatoshi Hikizu

Edge tracing is considered important for deformable object manipulation in order to spread and reveal the original shape of an object before it can be sorted. This paper proposes a unique real-time path-planning tracing method for clothes manipulation by robots. Tracing in this paper context involves tracing the clothes edge, with the robot arm movement based on the calculated path and feedback from sensors. Using tracing method to find a second corner has been proven to be efficient in finding (..)

Wei Li/ Tzong-Shi Liu/ Heng-I Lin/ Yi-Jeng Tsai

For the use of green energy and ubiquitous computing, this study investigates miniature electric generators that are constructed with piezoelectric benders. Electric power is generated by vibratory deformation of piezoelectric benders. Three different designs of piezoelectric generators are created and compared in this study by using mechanics analysis. The result shows that the cantilever design yields more power than symmetric and airfoil designs. Experimental results show that generated volta(..)
