This research introduces Expected Free Energy as a unified framework for autonomous robotic path planning, effectively balancing information gathering with resource constraints in environments like Mars exploration. By minimizing expected free energy under strict travel budgets, the proposed method outperforms classical baselines while simultaneously generating accurate environmental maps and locating high-value targets. The approach represents a significant advancement in machine learning applications for robotics, offering principled strategies that are both efficient and easy to tune for future autonomous deployments.
Expected Free Energy-based Informative Path Planning for Robotic Mars Exploration
arXiv:2608.14466v1 Announce Type: new Abstract: An autonomous robot efficiently exploring an unknown environment, such as looking for water sources on Mars, faces two simultaneous demands: building an accurate information map while quickly finding the regions of greatest value, and paying for every meter of travel and the cost of every measurement it takes. Classical information-seeking and reward-seeking criteria address only one of these objectives at a time. Here, we propose Expected Free Energy (EFE), the principled action-selection objective from active inference, as a unifying criterion for budgeted robotic informative path planning. Maintaining a Gaussian-process belief over the information field, our agent plans continuous trajectories that minimize expected free energy under hard path-length constraints. The results from multiple realizations show that EFE-based planning yields accurate posterior maps and locates the highest-value regions simultaneously, outperforming information-theoretic baselines under the same settings. In robotic exploration, these unified, easy-to-tune principled information-gathering strategies facilitate autonomous deployment while enforcing efficiency and resource constraints.
