Reasoning About the Spatial Relationships Derived From a RAPT Program for Describing Assembly by a Robot
نویسندگان
چکیده
The network reduction systen of RAPT, an o f f l ine object level language for programming robot assembly tasks is described in this paper. The task description is converted into a relat ional network with the positions of bodies as nodes, and rela tionships between positions as l inks. Rewrite rules based on the intersection and conposition of relations are used to simplify the network.

مدلسازی روابط توپولوژیک سه بعدی فازی در محیط GIS
Nowadays, geospatial information systems (GIS) are widely used to solve different spatial problems based on various types of fundamental data: spatial, temporal, attribute and topological relations. Topological relations are the most important part of GIS which distinguish it from the other kinds of information technologies. One of the important mechanisms for representing topological relations...

متن کاملExtending the Qualitative Trajectory Calculus Based on the Concept of Accessibility of Moving Objects in the Paths
Qualitative spatial representation and reasoning are among the important capabilities in intelligent geospatial information system development. Although a large contribution to the study of moving objects has been attributed to the quantitative use and analysis of data, such calculations are ineffective when there is little inaccurate data on position and geometry or when explicitly explaining ...
متن کاملA Q-learning Based Continuous Tuning of Fuzzy Wall Tracking
A simple easy to implement algorithm is proposed to address wall tracking task of an autonomous robot. The robot should navigate in unknown environments, find the nearest wall, and track it solely based on locally sensed data. The proposed method benefits from coupling fuzzy logic and Q-learning to meet requirements of autonomous navigations. Fuzzy if-then rules provide a reliable decision maki...
متن کاملSpatial Reasoning About Robot Compliant Movements and Optimal Paths in Qualitatively Modeled Environments
This paper describes a framework for qualitatively representing and reasoning about spatial conngurations. The framework contains interval/region based formalisms for describing distances, angles, and locations. These representations lead to the formulation of inference rules, as well as search-heuristics which enable the derivation of spatial relationships and paths among objects. The qualitat...
