The proposed control strategy is aimed at reducing the typical speed ripples of ultrasonic motors as well as compensating the load and temperature changes. Repetitive controllers are capable of improving the response of dynamical systems under periodic disturbances by learning from the stored error valves of preceding periods. Since it is desirable for the stabilizing compensator of repetitive controllers to be zero phase and perfect error tracker, the ZPET controller is a natural choice when the servo's closed-loop transfer function has non-minimum zeros. The performance of the proposed controller is compared against that of a PI-repetitive controller and its effectiveness experimentally demonstrated.","PeriodicalId":286422,"journal":{"name":"Proceedings 2000 ICRA.

Developing a web-enabled equipment driver for semiconductor equipment communications 开发用于半导体设备通信的网络设备驱动程序

{"title":"Developing a web-enabled equipment driver for semiconductor equipment communications","authors":"F. Cheng, Meng-Tsang Lin, R. Lee","doi":"10.1109/ROBOT.2000.846355","DOIUrl":"https://doi.org/10.1109/ROBOT.2000.846355","url":null,"abstract":"Equipment communications is essential for semiconductor manufacturing automation. Equipment managers generally function to communicate between the manufacturing execution system (MES) and equipment. To achieve generality and reusability, our previous work developed a generic equipment manager (GEMG). The rules governing the GEMG were divided into three independent portions: system/framework rules, business rules, and equipment rules. These rules were implemented in the MES interface, controller application (CA), and equipment driver (ED) modules, separately. Among them, equipment rules in the ED modules are equipment-dependent. Connecting a different machine to the GEMG requires modifying the associated ED accordingly, which is a difficult task. To solve this problem, this study proposes a web-enabled equipment driver (WED) that uses mobile object technology. Initially, a mobile object model with a Java applet, namely WED, is developed. WED is constructed on the equipment (server) side. Then, the equipment manager (client) downloads WED via a web browser. This process does not need to modify the ED. Subsequently, the equipment manager can communicate with the equipment by either the Java socket technology using the HSMS standard or the object web technology through the CORBA or DCOM protocols using the OBEM standard. This proposed scheme has been successfully implemented. Illustrative examples reveal that the proposed mobile object model and WED establish a novel, efficient, and versatile scheme for semiconductor equipment communications.","PeriodicalId":286422,"journal":{"name":"Proceedings 2000 ICRA.

Models of CPGs as systems of coupled nonlinear oscillators have been proposed and have been used for the control of robots. In this paper we describe the implementation of an adaptive CPG model in a compact, custom analog VLSI circuit. We demonstrate the function of the chip by controlling an underactuated, running robotic leg. This circuit has adaptive properties that allow it to tune its behavior based on sensory feedback. To our knowledge this is the first instance of an adaptive CPG chip. This approach supports the construction of extremely inexpensive, low power and compact controllers for walking, flying and swimming machines.","PeriodicalId":286422,"journal":{"name":"Proceedings 2000 ICRA.

First, the relationship between the stick area and the internal strain distribution of the finger is calculated using FE (finite element) analysis. Based on this relationship, a method is proposed for controlling the grasping force by decreasing the increasing ratio of the tangential force when the stick area is decreasing. Finally, the grasping force is controlled using an actual elastic finger, which is made of silicone rubber and in which strain gages are incorporated. It is confirmed that objects can be grasped using adequate grasping force without complete slippage, even when the weight and the friction coefficient of the objects are unknown.","PeriodicalId":286422,"journal":{"name":"Proceedings 2000 ICRA.

We developed an anthropomorphic head-eye robot \"WE-3R III\" (Waseda Eye No.3 Refined III) having auditory sensation, cutaneous sensation and a facial expression mechanism with eyes, eyelids, eyebrows, lips, a jaw and a neck. It is said that the human cutaneous sensations include contact, pressure, cold, warmth and pain, so a tactile sensor and a temperature sensor were mounted on the robot. For the tactile sensor, we adopted a force sensing resistor. We think that the difference in touching methods such as 'push', 'stroke' and 'hit' have an effect on emotion, therefore we developed the method for recognizing those differences, and installed it in the robot. By improving and rebuilding the artificial psychological model of WE-3RII using a new concept-equations of emotion-in a 3D mental space, we realized expression of the mental state affected by various stimuli with WE-3R III.","PeriodicalId":286422,"journal":{"name":"Proceedings 2000 ICRA.

This paper presents the companion results for haptic systems with environments having admittance causality, resulting in a slightly more complicated analysis. Although the main focus is on delay, the approach is valid for analysing any environment that exhibits non-passive behavior.","PeriodicalId":286422,"journal":{"name":"Proceedings 2000 ICRA.

A stability analysis of walking robots based on leg-end supporting moments 基于腿端支撑力矩的步行机器人稳定性分析

Zielińska","doi":"10.1109/ROBOT.2000.846457","DOIUrl":"https://doi.org/10.1109/ROBOT.2000.846457","url":null,"abstract":"An essential consideration in the development of any motion planning method for a multilegged vehicle is to maintain stability during walking. We propose a leg-end supporting moment (LSM) method, to measure the stability margin of walking robots. The LSM is defined as the product of the force acting on a supporting leg and the distance between the supporting leg and the opposite edge of the support polygon. These forces and distances can be obtained online from the internal robot sensors. The stability margin evaluated by the LSM method, expressed as LSM/sub m/, is defined as the quotient of the leg-end supporting moment over the weight of the robot. If the LSM/sub m/ is greater than zero, the robot is in stable state. Otherwise the robot will be in marginally stable state or will lose its stability. The simulation results show that the LSM method is suitable for the stability analysis in cases with and without external forces acting on the body. The method is not only effective for flat terrain, but also for uneven terrain. These characteristics enable the LSM method to measure the stability margin of a walking robot in the case of drilling, dragging and manipulating, also in the case when the robot is used in forestry.","PeriodicalId":286422,"journal":{"name":"Proceedings 2000 ICRA.

Multi-robot cooperation has rapidly emerged in many possible applications such as the plant maintenance, construction, and surgery, because it would have a significant advantage over a single robot in such cases. Thus, time-delayed control of a multi-robot system is expected to play an important role in remote operations, too. However, the effect of time-delay would pose a more difficult problem to the MOMR teleoperation systems and seriously affect their performance. In this work, first, we have built an experimental system to investigate the remote cooperation in MOMR teleoperation. Then, different coordinated control methods are proposed to cope with the collision, arising from the time delay over the network. To verify the validity of the proposed schemes, we have carried out various experiments on a planar block arrangement by two slave arms employing graphic simulators and a LAN subject to a significant communication delay.","PeriodicalId":286422,"journal":{"name":"Proceedings 2000 ICRA.
