Digital twins to embodied artificial intelligence: review and perspective
Bibliographic record
Abstract
Embodied artificial intelligence (AI) is reshaping the landscape of intelligent robotic systems, particularly by providing many realistic solutions to execute actions in complex and dynamic environments. However, Embodied AI requires a huge data generation for training and evaluation to ensure safe interaction with physical environments. Therefore, it is necessary to build a cost-effective simulated environment that can provide enough data for training and optimization from the physical characteristics, object properties, and interactions. Digital twins (DTs) are vital issues in Industry 5.0, which enable real-time monitoring, simulation, and optimization of physical processes by mirroring the state and action of their real-world counterparts. This review explores how integrating DTs with Embodied AI can bridge the sim-to-real gap by transforming virtual environments into dynamic and data-rich platforms. The integration of DTs offers real-time monitoring and virtual simulations, enabling Embodied AI agents to train and adapt in virtual environments before deployment in real-world scenarios. In this review, the main challenges and the novel perspective of the future development of integrating DTs and Embodied AI are discussed. To the best of our knowledge, this is the first work to comprehensively review the synergies between DTs and Embodied AI.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
