A gyroscope based on Coriolis effect and fabricated by Carbon Nanotube (CNT) was presented. The gyroscope was designed A CNT is vibration at x direction, when there a rotation around z direction, acceleration happens to the y direction. The natural frequency of MWCNT is depending on the inner diameter, outer diameter and length. The CNT was driven by the electrostatic force to its nature frequency. A CNT with a length of 1 μm was used for emitter and an anode with a bias angle is etched by Focused Ion Beam (FIB) which is set to the opposite to the CNT. An electrode is set near the CNT tip, which is employed to pulling the CNT for mechanical resonances by an AC voltage. The CNT with a resonate frequency of 1 MHz and mechanical quality factor Q of ∼400 was tested at rotation speed of 20 rad.s. © 2013 IEEE.

This paper presents construction of haptic scissors that can be used for surgical training, using the MATLAB-Simulink Real-Time Workshop environment and SolidWorks software. In this instrument we have force feedback in every position and angle of the scissors. The data which was already gathered in [1,2] for different tissues were used here. However, the previous simulations lack flexibility because only the exact information obtained during data acquisition are used. In this paper the data has been made smoother by using Neuro Fuzzy Controller. Design of a neuro fuzzy controller is considered in this work because of its insensitivity to disturbances and uncertainties of model parameters. The design and optimization process of neuro fuzzy controller is based on an extended learning technique derived from adaptive neuro fuzzy inference system (ANFIS), and implementation of this haptic scissors control system had been realized under MATLAB/SIMULINK environment. The experimental results demonstrates the efficiency of this design procedure. © 2012 IEEE.

Saw Blades can be applied to cut various types of plates, blocks and rods. Locking type precision saw blades consist of a disk-type tool (circular saw plate) holder on which insertable saw inserts are positioned radially outwardly. The inspection of saw blades is important in order to ensure their manufacturing quality and sawing performance. In practice, a plurality of cutting tool inserts must be assembled to a circular saw plate to form a functional locking type saw blades. However, the circular saw plate may contain defects such as thickness, geometric shapes and axial run-out of a circular saw plate. This study has successfully developed an inspection system to examine the critical geometry of locking type precision saw blades. In order to examine the axial run-out of a circular saw plate, a digital indicator is equipped to measure the heights of the blade continuously as the holder rotates around its axis. A non-contact optical inspection module is used to measure the geometric shapes of circular saw plate. The hardware of the inspection system includes spindle module, driving module, machine vision module and the digital indicator. Experiments meant to inspect locking type saw blade samples were also conducted in order to test the feasibility of the developed automatic inspection system. Based on the measuring data obtained from individual inspectors, the inspection system developed by this work shows a good repeatability and reproducibility.

Power consumption for each component in electric vehicle (EV) is very crucial since batteries capacity have limitation. Hence, it is essential to rectify the total using up power by each component because it has significant impact on batteries selection. Electric power steering (EPS) has been a popular preference over conventional steering system due to it simplicity, efficiency and requires least maintenance. This paper describes an assessment of power consumption of EPS using Fuzzy-PID controller. The performance of Fuzzy-PID controller is compared with conventional PID controller as well as uncontrolled EPS system. The EPS system was modeled using Matlab/Simulink and two steering behavior were simulated. The results have shown a power reduction of EPS system by using Fuzzy-PID over conventional PID controller. © 2012 IEEE.

Of late, many have shown great interests in the area of energy harvesting or energy scavenging. Researchers have been venturing into methods that can generate acceptable level of voltage since decades ago. In line with the spirit of green technology, energy harvesting will be a major contributor towards saving our environment in near future. Vibration energy harvesting, specifically, is getting more and more attention nowadays. With the abundant sources, this type of energy harvesting can generate desired voltage to power any low power devices and wireless sensor; and subsequently high power devices in the future. In this research, unimorph piezoelectric energy harvester is chosen to harvest wideband mechanical energy. The derivation of the mathematical modelling is based on the Euler-Bernoulli beam theory. MATLAB and COMSOL Multiphysics software are used to study the influence of the structure in generating output voltage due to base excitations. Finally, the results of the frequency response are displayed in the form of voltage within frequency range of 0 to 3500 Hz, at which the comb-shaped piezoelectric beam structure shows better performance as there exist more natural frequencies in the specified range of frequency.

IOP Conference Series: Materials Science and engineering 2013年第1期53卷

作者： Mohd Zoolfadli Md Salleh Nahrul Khair Alang Md Rashid Yasir Mohd Mustafah Mohd Zoolfadli is a member of Intelligent Mechatronic System Research Unit (IMS-RU) while Nahrul Khair Alang Md Rashid and Yasir Mohd Mustafah are with Autonomous Agent Research Group (AARG) of IIUM Department of Mechatronics Engineering International Islamic University Malaysia Gombak Selangor 50728 Malaysia

In this paper, we present an ongoing work on the autonomous navigation of a mobile service robot for Heat, Ventilation and Air Condition (HVAC) ducting. CCD camera mounted on the front-end of our robot is used to analyze the ducts openings (blob analysis) in order to differentiate them from other landmarks (blower fan, air outlets and etc). Distance between the robot and duct openings is measured using ultrasonic sensor. Controller chosen is ANFIS where its architecture accepts three inputs; recognition of duct openings, robot positions and distance while the outputs is maneuver direction (left or right).45 membership functions are created from which produces 46 training epochs. In order to demonstrate the functionality of the system, a working prototype is developed and tested inside HVAC ducting in ROBOCON Lab, IIUM.

Vehicles are the people's main means of transportation and thermal comfort in the vehicle cabin plays an important role. The heating, ventilating, and air-conditioning (HVAC) operation system in the vehicle cabin decides the degree of comfort, traffic safety as well as health of the occupants. The challenge of designing the HVAC control is to automatically achieve the thermal comfort, regardless of time varying weather conditions. Since most HVAC systems are complex with nonlinearity, distributed parameters, and multivariable therefore many classical controls do not necessarily yield a satisfactory control performance. This paper presents the development of temperature and humidity control strategy for HVAC based on Fuzzy Logic Control (FLC). The goal of the FLC-based temperature control is to satisfy the convergence and equilibrium property. The simulation test results have been shown a satisfactory to control the temperature and humidity.

This paper introduces a novel approach for measuring low pressures based on MEMS technology. In this technique the mechanism of squeeze film damping is used. A voltage is applied to a fixed-fixed MEMS beam and its step response is obtained;for each pressure there is a different response. Then the settling time is measured and we can relate each settling time with a defined pressure. Here, first we use some equations to relate pressure with the squeeze film damping effect;after that we use a micro beam model and relate its parameters with pressure. Then we use numerical analysis and simulation to show the procedure of pressure measuring. All simulation results are shown and discussed. © 2011 IEEE.
