Embodied Intelligence as a Systems Engineering Problem

Abstract & Introduction

AIA Orbis Engineering Group

Abstract: Embodied artificial intelligence introduces constraints that differ fundamentally from those of purely digital systems. Physical interaction requires real-time perception, safety guarantees, and reliable transfer of learned behavior from simulation to reality. This document analyzes embodied intelligence as a systems engineering problem, focusing on sim-to-real transfer pipelines developed within the AIA Orbis research context.

1. Introduction: Embodiment transforms intelligence from a representational problem into an interaction problem. Errors in physical systems manifest as safety risks rather than degraded outputs. As a result, embodied intelligence must be engineered with conservative assumptions and verifiable behavior.

Simulation and the Gap

2. Simulation as Architectural Necessity: Simulation provides a controlled environment for training and evaluation without physical risk. High-fidelity simulation enables systematic exploration of failure cases that would be impractical to reproduce in physical settings.

3. The Sim-to-Real Gap: Differences between simulated and real environments introduce performance degradation when policies are transferred without adaptation. This gap represents a structural risk rather than an implementation detail.

Training and Perception

4. Training Strategy: Policies are trained under domain-randomized conditions to encourage robustness. Curriculum-based progression exposes systems to increasing complexity while maintaining evaluability.

5. Transfer and Deployment: Deployment follows a staged process including calibration, shadow execution, and supervised activation. Each stage introduces additional safeguards and validation checkpoints.

6. Perception as Interaction Infrastructure: Depth-based perception provides spatial context necessary for safe interaction. Perception systems are designed to prioritize determinism and failure detection over semantic richness.

Control and Evaluation

7. Control and Supervision: Control architectures separate high-frequency actuation from lower-frequency perception and planning loops. Supervisory layers enforce safety constraints independent of learned policy behavior.

8. Evaluation and Validation: Evaluation scenarios vary environmental complexity, sensor noise, and human proximity. Metrics include task success, intervention frequency, and near-collision events.

9. Discussion: Embodied intelligence systems cannot be validated solely through performance metrics. They require structural guarantees that constrain behavior under uncertainty.

10. Conclusion: Sim-to-real transfer remains a central challenge in embodied intelligence. Addressing this challenge requires systems engineering approaches that integrate simulation, perception, control, and accountability.
