Mobile robots are increasingly used in automated industrial environments. There are also other applications like planet exploration, surveillance, landmine detection, etc. In all these applications, in order that the mobile robots perform their tasks, collision-free path planning is a prerequisite. This article provides an overview of the research progress in path planning of a mobile robot for...

Assembly lines are special flow-line production systems which are of great importance in the industrial production of high quantity standardized commodities. Recently, assembly lines even gained importance in low volume production of customized products (mass-customization). Due to high capital requirements when installing or redesigning a line, its configuration planning is of great relevance ...

the past, the process capability index (PCI) was the only one used in on-line quality management; there were no researches on off-line applications, such as product design or process planning. In using conventional PCI for off-line application, designers normally established the process mean close to the design target, and minimized the process variance so that the PCI value would be maximized....

Based on evolutionary computation (EC) concepts, we developed an adaptive evolutionary planner/navigator (EP/N) as a novel approach to path planning and navigation. The EP/N is characterized by generality, flexibility, and adaptability. It unifies off-line planning and on-line planning/navigation processes in the same evolutionary algorithm which 1) accommodates different optimization criteria ...

This paper summarizes recent work reported at ICAPS on applying artificial intelligence techniques to the control of production printing equipment. Like many other real-world applications, such as mobile robotics, this complex domain requires real-time autonomous decision-making and robust continual operation. To our knowledge, this work represents the first successful industrial application of...

The automated planning community has traditionally focused on the efficient synthesis of plans given a complete domain theory. In the past several years, this line of work met with significant successes, and the future course of the community seems to be set on efficient planning with even richer models. While this line of research has its applications, there are also many domains and scenarios...

Based on evolutionary computation (EC) concepts, we developed an adaptive Evolutionary Planner/Navigator (EP/N) as a novel approach to path planning and navigation. The EP/N is characterized by generality, exibility, and adaptability. It uni es o -line planning and on-line planning/navigation processes in the same general and exible evolutionary algorithm which (1) accommodates di erent optimiz...

In this paper we introduce an on-line planner implemented on MARIE, a real autonomous robot. Planning occurs at a high level, the planner controls other modules such as the path planner, which contain planners themselves. Plans are represented in a tree structure. The on-line planner has a library of partial trees to choose from when replanning is needed. We think that our research is unique in...

Abstract This study was intended to compare collaborative and individual task planning effects on Iranian EFL learners’ writing performance. Therefore, a group of 90 upper intermediate EFL learners were placed in three groups of Collaborative Task planning, Individual Task planning, and Control. In the experimental groups, participants were asked to do task planning collaboratively and individu...
