Introduction

Physics-Informed Machine Learning (Physics-Informed ML) for Robotics combines traditional physics-based modeling with machine learning techniques to help robots understand, predict, and operate in complex real-world environments. Instead of relying only on large amounts of training data, these systems incorporate physical laws, constraints, simulations, and engineering knowledge into AI models.

This approach is becoming increasingly important as robotics moves beyond controlled environments into dynamic spaces such as factories, warehouses, healthcare facilities, autonomous vehicles, aerospace systems, and research laboratories. Modern robotics requires better reliability, faster learning, improved safety, and reduced dependence on expensive real-world data collection.
