High-level autonomy requires discrete and continuous reasoning to decide both what actions take how execute them. Integrated Task Motion Planning (TMP) algorithms solve these hybrid problems jointly consider constraints between the symbolic (i.e., task plan) their geometric realization motion plans). This joint approach solves more difficult than approaches that address subproblems independentl...

We present a new probabilistic tree-of-roadmaps (PTR) planner that integrates discrete task planning and continuous motion planning using a probabilistic forward search. PTR is explicitly designed with two characteristics in mind: 1) it allows tasks to take continuously variable parameters as input, such as the location of contact points for a robot manipulator executing an object pickup task; ...

Today, Infrastructure-as-a-Service (IaaS) cloud providers have incorporated parallel data processing framework in their clouds for performing Many-task computing (MTC) applications. Parallel data processing framework reduces time and cost in processing the substantial amount of users’ data. Nephele is a dynamic resource allocating parallel data processing framework, which is designed for dynami...

In this paper we propose a generic task ontology, which formalizes the space of planning problems. Although planning is one of the oldest researched areas in Artificial Intelligence and attempts have been made in the past at developing task ontologies for planning, these formalizations suffer from serious limitations: they do not exhibit the required level of formalization and precision and the...

This paper presents a mission planning method for planetary rover. As a decision support system, mission planning is important for rover navigation and control. Generating travel path and task sequence synchronously is the key point. In this paper, the environment model of planetary surface is summed up as two parts which are obstacle map and timeline. According to this, the mission planner uti...

This paper reports on the development of the process-planning module for EDAPS, an integrated system for designing and planning the manufacture of microwave modules. Microwave modules are complex devices having both electrical and mechanical properties, and EDAPS integrates electrical design, mechanical design, and process planning for both the mechanical and electrical domains. EDAPS's process...

I. INTRODUCTION " Planning " , or selecting a sequence of actions to achieve a goal, has been a core focus of interest within the field of Artificial Intelligence (AI) since the field was founded in the 1950's. Initially, the focus of attention was on task planning which is concerned with sequencing actions within a symbolic representation of the state space [2]. When action costs are further i...

Planning of everyday tasks was examined in 48 inpatients with schizophrenia and 26 healthy controls. Participants were administered the Naturalistic Action Test, which requires completion of three everyday tasks (e.g., make toast and coffee). Planning variables, including planning behaviours (e.g., gathering items before engaging in a subtask) and planning time (e.g., period between task instru...
