Optimal Control of a Flexible Robot Arm

June 1, 1988
Author(s)
Jonathan W. Lee, B Wang
The work is a computer simulation of the control of a flexible robot arm. The dynamic equations for a single-link flexible robot arm have been derived rigorously. This arm has two degrees of freedom in rotation and one in translation so that the workspace

Performance Measures of a Robotic Micropositioner

June 1, 1988
Author(s)
Jonathan W. Lee, James S. Albus, Nicholas G. Dagalakis, T M. Tsai
This work describes a computer simulation of the dynamics and control of a robotic micropositioner. The robotic micropositioner is a parallel link manipulator which has six actuators, each controlled independently by a hydraulic system. The dynamic

Domain Images of Ultrathin Fe Films on Ag(100)

May 30, 1988
Author(s)
J L. Robins, Robert Celotta, john unguris, Daniel T. Pierce, B Jonker, G Prinz
Scanning electron microscopy with electron polarization analysis has been used to image domains of ultrathin Fe films grown epitaxially on a Ag(100) substrate. Room-temperature measurements show clearly the existence of large domains of in-plane

Message Authentication Code (MAC) Validation System: Requirements and Procedures

May 1, 1988
Author(s)
Miles E. Smid, Elaine B. Barker, David Balenson, Martha E. Haykin
The National Bureau of Standards Message Authentication Code (MAC) Validation System (MVS) tests message authentication devices for conformance to two data authentication standards: Federal Information Processing Standard Publication (FIPS PUB) 113,

Exploiting Computational Parallelism with a Hierarchical Robot Control System

April 29, 1988
Author(s)
John L. Michaloski, Thomas E. Wheatley, Ronald Lumia
Sequential machines do not provide enough computational perfomance for a real-time robot control system. Hierarchical structuring will be considered not only as a software development methodology, but also as a means for implementing a robot control system
