Spatial-Semantic Uncertainty in VLM-Based Target Search: Balancing Exploration and Identification
Alkesh K. Srivastava, Jonathan Diller, Vijay Kumar +1
Robots searching for a target from a natural-language description must determine not only where to search, but also which observed candidate is the desired target. These decisions…
When Information is Worth the Risk: Behavioral Valuation for Hazardous Robotic Exploration
Alkesh K. Srivastava, Aamodh Suresh, Carlos Nieto-Granda +1
Hazardous robotic exploration requires robots to map spatial risks, such as unsafe terrain, radiation, fire, mines, or structural damage, while operating where collecting informati…
A Kinetic Theory of Encounter-Based Information Propagation in Multi-Robot Systems
Alkesh K. Srivastava, Philip Dames
Multi-robot systems cannot assume persistent network connectivity. We study this problem through target tracking, where performance depends on how quickly target information is sen…
Robotic Video World Models: A Survey of Applications, Research Challenges, Future Directions
Zhiting Mei, Tenny Yin, Ola Shorinwa +9
Video world models have emerged as promising candidates for high-fidelity world models, offering the potential to synthesize high-quality videos capturing fine-grained interactions…
