9522963 Nnaju Research conducted under this award is to develop a product assembly modeler (PAM), which provides detailed information for successful mechanical or manual assemblies of a product. This modeler includes requirements for the assembly environment, feasible approach directions, precedence constraints, symmetries, and spatial relationships. The spatial relationships of the design give product specifications, functional requirements, and define the mating positions and degrees of freedom of motion of components. PAM is equipped with its own on-board graphics capabilities for visual assistance. This research applies the mathematical theory of symmetry to spatial reasoning in an effort to simplify the computation and geometric complexities of product assembly. If successful, the result will be a stand-alone product assembly moderler, designed to assist in the assembly of product that accurately demonstrates the designer's intentions.

Nnaju研究公司将根据该合同开发产品装配建模器（PAM），为成功的机械或手工装配产品提供详细信息。该建模器包括对装配环境、可行方法方向、优先约束、对称性和空间关系的需求。设计的空间关系给出了产品规格、功能要求，并定义了部件的配合位置和运动自由度。PAM配备了自己的机载图形功能，用于视觉辅助。本研究将对称的数学理论应用于空间推理，以简化产品装配的计算和几何复杂性。如果成功，结果将是一个独立的产品组装现代化器，旨在协助产品组装，准确地展示了设计师的意图。
