近些年来,随着计算机的计算能力和存储能力的飞速发展,科学计算的规模越来越大,在气象、生物技术、 油藏模拟、核技术等领域,用于计算的网格已达到百万、千万乃至数十亿,计算的数据结果也已达到 GB 乃至 TB 大小。而和计算、存储技术的飞速发展相比,由于受材料、电子等工艺的限制,计算机的显示尺寸的发展相对滞 后。如何能够快速、准确的表现海量数据已经成为一个亟需解决的问题。它不仅包括如何以更大的屏幕来显示数 据,还包括如何以更快的速度来处理数据。 使用并行计算技术的大屏幕显示是解决上述问题一个很好的途径。采用多个显示设备取代原来的单个显示设 备使得显示屏幕增大为相应的倍数;各个显示设备由单独的计算机进行驱动,计算任务的分担使得显示速度也大 大提高。 除了在科学计算方面的应用外,大屏幕显示作为一种“半沉浸式”的虚拟环境,在虚拟战场、视频会议、公 共场合演示等方面也有着广泛的应用。 大屏幕显示技...

This paper focuses on developing a control method for a single-master multi-slave (SMMS) system to cooperatively control a team of mobile agents for multi-robot multi-task multitarget (MRMTMT) pairing. Major components of the developed control method are (1) modified potential field based leader-follower formation, (2) adaptive master-slave impedances, (3) compensation for human induced errors ...

In this paper, we propose automatic generation of bus-based communication architectures from an abstract model reflecting only the communication topology. Tasks include protocol selection for each bus, master/slave assignment for each component, interrupt handling and addressing for synchronization between components, and arbitration to resolve multiple accesses on a bus. We present a set of ex...

Resource selection is fundamental to the performance of master/slave applications. In this paper, we address the problem of promoting performance for distributed master/slave applications targeted to distributed, heterogeneous ”Grid” resources. We present a work-rate-based model of master/slave application performance which utilizes both system and application characteristics to select potentia...

A servo manipulator system has been developed for remotely handling radioactive materials in a hot cell [1]. Unlike a robot manipulator, a servo manipulator is monitored and controlled by an operator all the time. A robot manipulator performs a taught or programmed task without an operator. Generally, a servo manipulator consists of a master arm and a slave arm. The slave arm is a device for wo...

This paper analyzes the position control of a master-slave synchronization robotic arm driven by D.C. motor using PID (Proportional, Integral, and Derivative) controller with software hardware design. works to achieve exact desired simultaneously for master slave robot minimal defects. The transfer function arms used in this research is calculated black box modelling. MATLAB Simulink block test...

An interface based on inertial sensors with applications for master slave robotic teleoperation is developed. The interface is composed of two portable inertial sensor units which are placed on the upper and lower arm in order to obtain acceleration and turning rates. The data is internally processed by a DSP in the sensors and yields orientation measurements of the bodies they are attached. Th...

This paper presents a new teleoperation approach using a virtual spring, and local contact force control on the slave robot. The operational space framework provides the control structure needed to achieve decoupled task dynamics. A virtual spring connects the master and slave systems and a closed-loop force controller compensates for the dynamics of the slave system, rendering transparent the ...

In this paper, the analysis and design of master-slave teleoperation systems are discussed. The goal of this paper is to build a superior master-slave system that can provide good maneuverability. We first analyze a one degree-of-freedom system including operator and object dynamics. Second, some ideal responses of master-slave systems are defined and a quantitative index of maneuverability ...

We present a stable regime of asymmetric bound states for spiral pairs in a generic numerical model of a homogeneous excitable medium. In this regime, one spiral tip (slave) rotates around the other (master). Master-slave dynamics occur for both same-chirality and opposite-chirality spiral pairs in a range of parameters and initial conditions. We study the dependency of master-slave characteris...
