Gross-motion planning for assembly is commonly considered as a distinct, isolated step between task sequencing/scheduling and ne-motion planning. In this paper we formulate a problem of delivering parts for assembly in a manner that integrates it with both the manufacturing process and the ne motions involved in the nal assembly stages. One distinct characteristic of gross-motion planning for a...

Assembly planning plays a major role in the manufacturing industry. In order to reduce computational complexity, this paper presents a knowledge-based approach to the assembly sequence planning problem. The CSBAT (connection-semantics-based assembly tree) hierarchy proposed in this paper provides an appropriate way to consider both geometric information and non-geometric knowledge. In this rese...

A green design for assembly model is presented to integrate design evaluation and assembly and disassembly sequence planning by evaluating the three activities in one integrated model. For an assembled product, an assembly sequence planning model is required for assembling the product at the start of the product life cycle. A disassembly sequence planning model is needed for disassembling the p...

Gross-motion planning for assembly is commonly considered as a distinct, isolated step between task sequencingscheduling and fine-motion planning. In this paper we formulate a problem of delivering parts for assembly in a manner that integrates it with both the manufacturing process and the fine motions involved in the final assembly stages. One distinct characteristic of gross-motion planning ...

Space-based robotic systems for diagnosis, repair and assembly of systems will require new techniques of planning and manipulation to accomplish these complex tasks. ' results of work in assembly task representation, discrete-ohd synthesis which provide a design environment for flexible assembly systems in manufacturing applications, and which extend to planning-of manipulation operations in un...

Planning for assembly requires reasoning about various tools used by humans, robots, or other automation to manipulate, attach, and test parts and subassemblies. This paper presents a general framework to represent and reason about geometric accessibility issues for a wide variety of such assembly tools. Central to the framework is a use volume encoding a minimum space that must be free in an a...

Virtual assembly process planning (VAPP) provides a more efficient, intuitive and convenient method for assembly process planning. Previous efforts in this field are concentrated on how to assemble components together and how to analyze this assembly process in a virtual environment. However, how the interactive planning process can be modeled and organized, which is important for VAPP because ...
