Automation of unstructured production environment by applying reinforcement learning

Abstract

Implementation of Machine Learning (ML) to improve product and production development processes poses a significant opportunity for manufacturing industries. ML has the capability to calibrate models with considerable adaptability and high accuracy. This capability is specifically promising for applications where classical production automation is too expensive, e.g., for mass customization cases where the production environment is uncertain and unstructured. To cope with the diversity in production systems and working environments, Reinforcement Learning (RL) in combination with lightweight game engines can be used from initial stages of a product and production development process. However, there are multiple challenges such as collecting observations in a virtual environment which can interact similar to a physical environment. This project focuses on setting up RL methodologies to perform path-finding and collision detection in varying environments. One case study is human assembly evaluation method in the automobile industry which is currently manual intensive to investigate digitally. For this case, a mannequin is trained to perform pick and place operations in varying environments and thus automating assembly validation process in early design phases. The next application is path-finding of mobile robots including an articulated arm to perform pick and place operations. This application is expensive to setup with classical methods and thus RL enables an automated approach for this task as well.

“…Reinforcement Learning (RL) algorithms [1] have emerged as a pivotal force reshaping the scientific landscape by offering unprecedented capabilities to learn optimal actions leading to eventual success in uncharted environments, all without the need for external supervision. This transformative paradigm has found application across a spectrum of domains, ranging from self-driving cars [2,3], industrial automation [4,5], trading and finance [6], healthcare [7], gaming [8,9], to the intricacies of optics [10][11][12].…”
