Action-Inclusive Multi-future Prediction Using a Generative Model in Human-Related Scenes for Mobile Robots

Mobility in daily unstructured environments, particularly in human-centered scenarios, remains a fundamental challenge for mobile robots. While traditional prediction-based approaches primarily estimate partial features for robot decision making, such as position and velocity, recent world models enable direct prediction of future sensory data. However, their potentials in human-inclusive environments remain underexplored. To assess the feasibility of world models in facilitating human-robot interactions, we propose a robot framework using a deep generative model that jointly predicts multiple future observations and actions. Our approach leverages first-person-view (FPV) raw sensor data, integrating both observations and actions to enhance predictive capabilities in dynamic human-populated settings. Experimental results demonstrate that our method is capable of generating a range of candidate futures for one condition and planning actions based on observation guidance. These findings highlight the potential of our approach for facilitating autonomous robots’ coexistence with human.
