Abstract

A method for verifying completion of a task is provided. In various embodiments, the method includes obtaining location coordinates of at least one location sensor within a work cell. The at least one sensor is affixed to a tool used to operate on a feature of a structure to be assembled, fabricated or inspected. The method additionally includes, generating a virtual object locus based on the location coordinates of the at least one location sensor. The virtual object locus corresponds to a computerized schematic of the structure to be assembled and represents of all possible locations of an object end of the tool within the work cell. The method further includes, identifying one of a plurality of candidate features as the most likely to be the feature operated on by the tool. The identification is based on a probability calculation for each of the candidate features that each respective candidate feature is the feature operated on by the tool.
