Predesign of a simulator for inverse robot kinematics

An inverse robot kinematics method is being developed that is to be applicable to any sequential rigid robot. In this report, first requirements are identified and a survey of existing methods is given. An. evaluation of these methods with respect to the requirements then shows that a method based on optimization is the best candidate. It...

ISMuS : An information system to support the development of digital simulation models for multibody systems motivation, requirements and concept

The National Aerospace Laboratory NLR In the Netherlands develops simulation systems that are used by industry to evaluate product designs by means of digital simulation studies. Such systems Involve simulation models and simulation tools. The simulation models are software representations of the product that is to be evaluated. As such, the...

Development environment for digital simulation models of multibody systems

Requirements are formulated for an environment for development, verification and validation of digital simulation models of multibody systems. A realization of such an environment at the National Aerospace Laboratory NLR is described.

Software requirements document for the non-real time HSF software for level 3 HERA on-board control

This document contains the software requirements for the non-real-time HSF software for level 3 HERA on-board control. Software requirements for the level 3 HERA on-board control itself, having been generated in a separate study, are transformed to the non-real-time simulation facility environment and the requirements for the software supporting...

A software design tool for the analysis of robot dynamics properties

Design of robots is an iterative process. Therefore software tools for analysis of different concepts without the need to build hardware models are required. The software tool ROBDYN can be used for analysis of the dynamics properties of a robot. Main constituents are a dynamics algorithm and a facility for the preand postprocessing of data. The...

Inexact reasoning in expert systems: An integrating overview

In this report several methods for modeling uncertainty in expert systems are discussed. An overview is given of methods used in various existing expert systems and an attempt is made to put these methods into their proper perspective.
