A typical robot assembly operation involves contacts with the parts of the product to be assembled and consequently requires the knowledge of not only position and orientation trajectories but also the accompanying force-torque profiles for successful performance. To learn the execution of assembly operations even when the geometry of the product varies across task executions, the robot needs t...

This study set out to explore the impact of three levels of task planning on the accuracy of task-based oral performance with narrative task types among sixty Iranian sophomores majoring in Teaching English as a Foreign Language (TEFL) at Islamic Azad University – Tabriz Branch. It was hypothesized that simultaneous pre-task/on-line planning would lead to more accurate performance. To test the ...

This paper describes the need to view a planner as situated in an environment dealing with the whole planning problem While a planning agent deals with plan generation aspects other agents are concerned with aspects such as task elicitation plan analysis reactive execution plan repair etc Each of these systems has its own perspective on the planning problem and each of the systems must be capab...

This paper discusses an iterative, engineering approach with an improved Conceptual Design Stage for the design of better hypertext. We emphasize the importance of getting design right “up front” so that many design blunders can be avoided. Task analysis and cognitive user modelling techniques are used to make design recommendations for rapid prototyping and testing of a prototype hypertext. We...

In recent years, the problem of inferring and utilizing semantic information has gained considerable interest within the mobile robotics community. In this paper we focus on the problem of how to utilize the local semantic information of objects in a map to solve a navigation task more efficiently. In particular, we consider a wayfinding task and choose a supermarket environment as an example d...

objectives: the aim of this study was to identify the role of attentional process in postural control using choice reaction time task while changing the visual and proprioceptive cues under difficult balance task (standing on one-leg). methods: this cross-sectional study was conducted by participating 20 young people (22.75±2.29). each subject performed one-leg standing as balance task for each...
