建议的研究解决了电容的发展 可以检测感兴趣的几何特征的接近传感器阵列 例如表面的边缘、孔的位置、 工件相对于端部执行器的距离，以及端部执行器之间的距离。 效应器和工件，同时避免了大量的计算 通常与机器视觉相关的要求和其他问题 系统. 该项目还将充分探讨这种技术的使用， 自动表面质量传感器系统， 表面轮廓的定量测定和表征， 技术表面上的缺陷，与光学和磁性无关 表面的性质。 传感器将能够 定量确定局部和平均表面粗糙度， 表面缺陷的深度和大小。 该传感器由一个薄的短引线嵌入在硬陶瓷 衬底，因此是坚固的，并且由于其小尺寸， 配置为几乎任何所需的形状，以检查难以达到 表面。

The proposed research addresses the development of capacitive proximity sensor arrays that can detect geometric features of interest such as edges of surfaces, locations of holes, spatial angles of workpieces relative to an end-effector, and distance between end- effectors and workpiece, while avoiding the extensive computing requirements and other problems typically associated with machine vision systems. The project will also explore the use of this technique in a fully automated surface-quality transducer system which will allow the quantitative determination and characterization of surface profiles and defects on technical surfaces, independent of the optical and magnetic properties of the surface. The transducer will be capable of quantitatively determining local and average surface roughness as well as depth and size of surface flaws. The sensor consists of a thin short lead embedded in a hard ceramic substrate, and is therefore rugged and can, due to its small size, be configured to almost any desired shape in order to examine hard-to-reach surfaces.
