Your role and responsibilities

Digital Twins are increasingly used in industrial robotics for simulation, virtual commissioning, and robot learning. However, differences between simulated and physical systems can emerge due to uncertain or changing robot, task, and environment characteristics. These Real–Sim discrepancies can reduce the accuracy and reliability of Digital Twins and limit their use for Physical AI and Sim-to-Real applications.

This thesis investigates how information from a physical robotic system can be used to evaluate, adapt, and improve its Digital Twin, and how the improved twin can in turn support better prediction, validation, or learning for the physical system. The goal is to explore methods and architectures for establishing a bidirectional Real–Sim–Real interaction, where the Digital Twin can evolve based on physical experience rather than remaining a static model.

The student will investigate different approaches for identifying and reducing the Reality Gap. Possible directions include physics-based model adaptation, system identification, data-driven or learning-based methods, state estimation, hybrid physics–learning approaches, or combinations thereof. Architectures such as Shadow and Predictive Twins may also be explored, but the student is encouraged to investigate and compare alternative solutions.

The methodology should be generally applicable to industrial robotic systems. A dual-arm robotic system may be used as an experimental demonstrator.

Details

Period: January to July 2027

Number of credits: 30 ECTS/högskolepoäng (hp)

Number of students: 1

Location: on-site, Västerås

The main tasks are

Literature review: Investigate the state of the art in bidirectional and adaptive Digital Twins, Real–Sim adaptation, simulation fidelity, system identification, and learning-based approaches for robotics.

Problem formulation: Identify relevant sources of Real–Sim discrepancy and determine which robot, task, and environment characteristics are most important to observe and adapt.

Method investigation: Explore and compare suitable approaches for using physical robot experience to evaluate and improve the Digital Twin. This may include physics-based, data-driven, learning-based, or hybrid approaches.

Digital Twin framework: Design and implement a suitable bidirectional Real–Sim–Real framework based on the findings of the investigation.

Evaluation: Define appropriate metrics for Digital Twin fidelity and evaluate the selected approach under controlled variations in the robot, task, or environment.

Validation: Demonstrate and assess the developed framework on an industrial robotic manipulation scenario, potentially using a dual-arm robotic system.

The expected outcome is an investigation and experimental evaluation of methods for adaptive bidirectional Digital Twins, together with a demonstrated framework showing how physical robot experience can be used to improve Digital Twin fidelity and how the improved twin can support subsequent robot operation or Physical-AI applications.

The work can provide a foundation for future research in areas such as predictive simulation, synthetic data generation, robot learning, Sim-to-Real transfer, predictive validation, and continual learning.
