The Challenge: Modern robotic systems must operate safely and robustly in dynamic environments where conventional assumptions about scene stability are constantly violated.
This workshop AIR4D explores the cutting-edge intersection of 4D robotics—where spatial perception meets temporal context—addressing the fundamental challenges of dynamic localization, real-time reconstruction, high-fidelity rendering, and generative modeling in ever-changing environments.
Through engaging keynotes, paper presentations, and interactive discussions, participants will discover state-of-the-art approaches that enable robots to not just perceive their environment, but truly understand its temporal dynamics. We aim to establish standardized benchmarks, discuss novel evaluation protocols, and foster cross-disciplinary collaborations that will shape the next generation of intelligent robotics.
Key Focus Areas:
- Dynamic Localization: Real-time positioning in changing environments
- Temporal Reconstruction: Building 4D world models from sensor data
- Differentiable Rendering: High-fidelity view synthesis for robotic perception
- Scene Generation: Creating realistic dynamic environments for training and simulation

Topics
We welcome submissions addressing intelligent robotics in 4D scenes. Relevant topics include, but are not limited to:
Establishing metrics, datasets, and benchmarks to evaluate performance in camera tracking, mapping, rendering, and scene understanding for dynamic environments.
Building 4D spatiotemporal models from multimodal sensor data, capturing geometry, motion, and dynamic interactions over time.
Integrating high-fidelity differentiable rendering pipelines to enable photorealistic view synthesis and perception-aware planning.
Creating interactive and realistic dynamic environments—both simulated and real—that reflect human-centric structures, behaviors, and semantics for training and evaluation.
Applying 4D scene understanding in robotics applications such as autonomous navigation, social robotics, and digital twins to enhance decision-making and human-robot interaction.
