Abstract

A method for robotic adaptive production includes modifying program instructions online while performing production activities in response to detecting a change in the production environment. A robotic adaptive production method includes modifying program instructions online while performing production activities to minimize a production task cycle time or improve a production task quality. A robotic adaptive production method includes estimating a relationship between a control parameter and a sensor input; and modifying the control parameter online to achieve an updated parameter based on the estimating. A robotic adaptive production method includes receiving sensor input relating to robotic performance during the performance of production tasks and online optimizing a process parameter based on robotic performance during the performance of the production tasks. A robotic adaptive production method includes determining the position and/or orientation of a feature based on a learned position and/or orientation of another feature and on a geometric relationship.
