Failing Gracefully: Mitigating Impact of Inevitable Robot Failures
Duc M. Nguyen, Saad A. Ghani, Andrew Marshall +3
Service robots operate in household environments shared with humans, pets, and everyday objects, where they are highly susceptible to failures such as software crashes, hardware de…
Courteous Anticipation: Improving Long-Lived Task Planning in Persistent Shared Environments
Md Ridwan Hossain Talukder, Roshan Dhakal, Elizabeth Phillips +1
We consider a task planning scenario in which robots sharing a persistent environment are assigned tasks one at a time from a held-out sequence. Standard task planners, lacking for…
Scout-Assisted Planning for Heterogeneous Robot Teams under Partially Known Environments
Hoang-Dung Bui, Abhish Khanal, Raihan Islam Arnob +1
Autonomous robot teams navigating partially known environments face costly backtracking when ground robots encounter blocked roads that are only revealed upon physical traversal. W…
Why Do LLM-based Web Agents Fail? A Hierarchical Planning Perspective
Mohamed Aghzal, Gregory J. Stein, Ziyu Yao
Large language model (LLM) web agents are increasingly used for web navigation but remain far from human reliability on realistic, long-horizon tasks. Existing evaluations focus pr…
Multi-robot Graph Traversal with Support Coordination under Stochastically Moving Adversaries
Manshi Limbu, Xuan Wang, Gregory J. Stein +2
Cooperative multi-robot missions require team of robots to traverse environments where adversaries or hazards with stochastic dynamics induce time-varying traversal risk. While sup…
