Integrating Diagnostic Reasoning in Execution Monitoring

Posted on May 24th, 2015

For reliable and fault tolerant operation of cognitive factories, we introduce an algorithm to monitor plan executions. According to this algorithm, when some changes or discrepancies are detected, appropriate decisions are given based on the causes of these changes or discrepancies. To identify these causes (e.g., broken robots or robot components), we introduce a novel diagnostic reasoning method which synergistically integrates hypothetical reasoning, geometric reasoning, and learning from earlier experiences. Based on these causes, if necessary, new hybrid

Cognitive Toy Factory with Two Teams of Heterogeneous Robots

Posted on September 16th, 2013

We consider a toy factory with two teams of robots, where each team is located in a separate workspace collectively working toward completion of an assigned task. In particular, Team 1 manufactures nutcracker toy soldiers through the sequential stages of cutting, carving and assembling, while Team 2 processes them by going through stages of painting in black, painting in color, and stamping. Each workspace is depicted as a grid, contains

Cognitive Factories

Cognitive factories are a new paradigm in production engineering towards a more flexible, adaptable, and reliable production. According to this paradigm, the machines and processes in a factory are equipped with cognitive capabilities that involve reasoning about goals, perception, actions, collaborative task execution, etc. to allow them to assess and increase their scope of operation autonomously.

Planning and Execution Monitoring

Planning and Execution Monitoring

We propose the use of causality-based formal representation and automated reasoning methods from artificial intelligence to endow multiple teams of robots in a factory, with high-level cognitive capabilities, such as optimal planning and diagnostic reasoning. We present a framework that features bilateral interaction between task and motion planning, and embeds geometric reasoning in causal reasoning. We embed this planning framework inside an execution and monitoring framework and show its applicability
