Title:
SYSTEMS AND METHODS FOR ADVANCE ANOMALY DETECTION IN A DISCRETE MANUFACTURING PROCESS WITH A TASK PERFORMED BY A HUMAN-ROBOT TEAM
Document Type and Number:
WIPO Patent Application WO/2021/112255
Kind Code:
A3
Abstract:
A system for detection of an anomaly in a discrete manufacturing process (DMP) with human-robot teams executing a task. Receive signals including robot, worker and DMP signals. Predict a sequence of events (SOEs) from DMP signals. Determine whether the predicted SOEs in the DMP signals is inconsistent with a behavior of operation of the DMP described in a DMP model, and if the predicted SOEs from DMP signals is inconsistent with the behavior, then an alarm is to be signaled. Input worker data into a Human Performance (HP) model, to obtain a state of the worker based on previously learned boundaries of human state. The state of the HW is then input into the HRI model and the DMP model to determine a classification of anomaly or no anomaly. Update a Human-Robot Interaction (HRI) model to obtain a control action of a robot or a type of an anomaly alarm.
