Abstract: Disclosed herein is a method and apparatus for observing a manufacturing line, wherein the manufacturing line includes at least one robotic element for moving at least one part, the method comprising receiving, at a processor separate from the manufacturing line, sensor data about the at least one robotic element, and when the sensor data exceeds a boundary condition, triggering a feed-back collection event. The feed-back collection event includes identifying a stream of sensor data, capturing feed-back data at a data collection device associated with the at least one robotic element, tagging the feed-back data to reflect the at least one part associated with the boundary condition, identifying, within the feed-back data, when the boundary condition is exceeded by the at least one part in real time, and storing the feed-back data relating to the boundary condition in association with the sensor data and the boundary condition.
