Using piezoelectric ceramics as micro driving elements, based on the inertia-friction driving principle, a ball base microactuator is designed in this paper. It has centimeter scale's rotate displacements micro/nanometer scale's rotate positioning precision and three degrees of freedom. It detailed analyzes the discharge of PZT and its influence on the signal waveform generated by hard circuits. Especially, it divides the inherent discharge time of PZT into three small stages to analyze the kinematics and dynamics characteristics of the metal ball on each small stage. Kinematics and dynamics mathematical model of the metal ball on each small stage are set up. An impact force model acts on the metal ball is set up based on the momentum law. A back rotation model of the ball also set up in this paper. Experimentations prove the mathematical model of back rotation is reasonable in some degree.

The MRISS can control the appliance control module using wireless RF interface. The user can remote control appliance using cell phone through GSM module, too. The appliance module can feedback reaction result to the user through cell phone. First, we develop the communication protocol in MRISS, and design the multiple interface security robot, security module and appliance control module. Then we implement the MRISS function using the proposed method applying in security detection and appliance control. We can monitor the condition in home or building through Internet, and receive a message of the detection information to cellular phone using wireless RF interface embedded in the ISR. We can also use cell phone to instruct ISR to control appliances. ISR controls appliances via wireless RF module.

The need for nanometer resolution positioning technique draws significant attention for semi-conductor industry, biotechnology, and nanotechnology. This paper presents a design of friction-drive rotary stage driven by piezoelectric (PZT) actuator. This stage includes a multiplayer PZT actuator, Scott Russel mechanism, an actuation stage, a pre-load spring and an output shaft. The rotary positioning in this paper is accomplished by the stick-slip effect which a piezoelectric generated force is applied to produce an opposite angular momentums of the rotor to overcome the static friction and to achieve a relative motion. The optimum performance of the stage was achieved by adjusting the pre-load of a spring. Finite element analysis and Taguchi optimization method were extensively conducted to analyze the displacement, stress and vibration behavior for optimum design. Using the wire electro-discharge-machining (EDM), the rotary stage was fabricated and its performance was evaluated. The stage reaches the resolution of 0.13 rad and speed of 0.15 degrees per hour. The rotary positioner can be used in wafer fabrication and SEM for nano-manipulation.

Autonomous stereo visual guidance and control of mobile robots 移动机器人自主立体视觉导引与控制
Pub Date : 2005-07-10 DOI: 10.1109/ICMECH.2005.1529238
Wen-Chung Chang, Shuying Lee
This paper presents the design and implementation of a stereo visual guidance and control system for mobile robots. A stereo vision system is proposed which is capable of reconstructing 3D map based on observed geometrical features without a priori knowledge on the environments. Specifically, detected edge features in binocular images are processed in Hough space for matching correspondence before 3D reconstruction. The generated 3D map can be effectively updated using visual tracking techniques for matched features together with correspondence matching algorithms for newly-observed features. Moreover, based on the reconstructed 3D map, the desired trajectory can be determined. Thus a visual feedback control law can be synthesized for a robot to follow the desired trajectory. Specifically, angular velocity commands are transmitted to a 8051-based driver module to execute low level control of DC motors and video cameras. Due to the fact that visual tracking is employed to assist in maintaining correspondence information and reduce redundant computation, the proposed system can be operated in real time. The proposed system is successfully validated through experiments in indoor environments.
本文介绍了一种移动机器人立体视觉导引与控制系统的设计与实现。提出了一种立体视觉系统,该系统能够在不需要先验环境知识的情况下,根据观察到的几何特征重建三维地图。具体而言,在三维重建之前,将检测到的双目图像边缘特征在霍夫空间中进行匹配对应处理。利用匹配特征的视觉跟踪技术和新观测特征的对应匹配算法,可以有效地更新生成的三维地图。此外,基于重建的三维地图,可以确定所需的轨迹。因此,可以合成一个视觉反馈控制律,使机器人沿着期望的轨迹运动。具体来说,角速度命令被传输到基于8051的驱动模块,以执行直流电机和摄像机的低级控制。由于采用视觉跟踪来辅助通信信息的维护和减少冗余计算,该系统可以实时运行。通过室内环境实验,验证了该系统的有效性。

Chun-Hao Li, M. Tsai, Jeun-Jye Li
This paper inform us the advantage of laser burning technology by using the absorption of the laser energy on the material of brushes to produce the melting ball on the top of wire pins, the results would be better than traditional fuel burning methods. Laser has Gauss-beam mode with average energy-distribution to get stable long term operation and small HAZ (heating affect zone), so these brushes would have smooth curve of ball wire pins to make nice touch for skin or surface. For improving the traditional industrial manufacturing process, it is one suitable solution to use laser technology on burning engineering for molding wire pins.

This study proposes a new automatic bicycle-borne measurement system to quantify the pressing force on the pedals, detect the pedal cranks' rotations, compute the rear wheel's traveling distance and speed, calculate the accumulated calories burned and the equivalent fat loss incurred within the rider through cycling and, in addition, render a travel clock. The proposed system, with a built-in microprocessor, processes the measured data and displays the computed output, including the time, the traveling distance and speed, the accumulated calories burned and the equivalent weight (fat) loss during the cycling, via an LCD panel. The computation methods are detailed. The proposed system would convert a regular bicycle into a unique double-purpose equipment for both traveling and fitness exercise, usable both indoors and outdoors on both sunny and rainy days. The test results of this study's prototype are also listed and compared with standard or reference data in this paper.

The advantages of an all-electric injection molding machine are energy saving, quieter, cleaner and more accurate. In recent years, the development of all-electric injection molding machines progress rapidly. The core technology of the all-electric injection molding machine is using servomotors to drive all the processes such as injection, clamping, plasticating et al.. The injection unit plays a very important role in the injection molding machine. The injection unit controls many parameters such as injection speed, injection pressure, packing pressure et al.. All the parameters will influence the quality of products. The tiebarless structure is used for the clamping unit in our machine. It can provide larger space for large molds in a smaller machine combined with quicker mold changes. Those advantages can save much time. This paper demonstrates our effort in designing and fabricating an all-electric tiebarless injection molding machine, which has six tons of clamping force.

The physiological signals such as electrocardiogram, respiration, blood pressure, etc. can reveal the spontaneous status of human physiology, but this benefit is usually degraded by wire connection between the recording sites and the processing unit. Several multi-user communication protocols such as Bluetooth, IEEE 802.11 etc. have been widely used in personal wireless communication. However, the power consumption reduces the time duration of long-term monitoring and the complex protocol requires a complicated microprocessor to handle the communication packets. In this paper, we developed a slotted-ALOHA communication protocol to allow several physiological signals to be transmitted simultaneously in a single communication channel. The protocol is so simple that it can be implemented in a small-size and low-power microcontroller. Furthermore, a 2.4-GHz RF transceiver (nRF2401, NORDIC) was incorporated into a 16-bit microcontroller (MSP430, Texas Instruments). The slotted-ALOHA communication protocol was implemented in the developed system. The result demonstrated the feasibility of the proposed communication protocol.
诸如心电图、呼吸、血压等生理信号可以揭示人体生理的自发状态,但由于记录点与处理单元之间的电线连接,通常会降低这种好处。蓝牙、IEEE 802.11等多用户通信协议已广泛应用于个人无线通信中。然而,功耗降低了长期监控的持续时间,并且复杂的协议需要一个复杂的微处理器来处理通信数据包。在本文中,我们开发了一种开槽aloha通信协议,允许多个生理信号在单个通信通道中同时传输。该协议非常简单,可以在小尺寸、低功耗的微控制器中实现。此外,将2.4 ghz射频收发器(nRF2401, NORDIC)集成到16位微控制器(MSP430, Texas Instruments)中。在开发的系统中实现了开槽aloha通信协议。结果证明了所提出的通信协议的可行性。
