Fast When, Careful Who: Dual-Process Multiparty Turn-Taking with Diffusion Augmentation
Rutherford A. Patamia, Ming Liu, Wei Luo +2
Reliable turn-taking is essential for spoken dialogue systems. However, most existing methods are designed for two-speaker interaction and struggle with realistic multiparty audio…
Geometrically Plausible Object Pose Refinement using Differentiable Simulation
Anil Zeybek, Rhys Newbury, Snehal Dikhale +3
State-of-the-art object pose estimation methods are prone to generating geometrically infeasible pose hypotheses. This problem is prevalent in dexterous manipulation, where estimat…
Optimizing Robotic Placement via Grasp-Dependent Feasibility Prediction
Tianyuan Liu, Richard Dazeley, Benjamin Champion +1
In this paper, we study whether inexpensive, physics-free supervision can reliably prioritize grasp-place candidates for budget-aware pick-and-place. From an object's initial pose,…
A Service Robot's Guide to Interacting with Busy Customers
Suraj Nukala, Meera Sushma, Leimin Tian +2
The growing use of service robots in hospitality highlights the need to understand how to effectively communicate with pre-occupied customers. This study investigates the efficacy…
Collaborative Object Handover in a Robot Crafting Assistant
Leimin Tian, Shiyu Xu, Kerry He +3
Robots are increasingly working alongside people, delivering food to patrons in restaurants or helping workers on assembly lines. These scenarios often involve object handovers bet…
Virtual Traffic Lights for Multi-Robot Navigation: Decentralized Planning with Centralized Conflict Resolution
Sagar Gupta, Thanh Vinh Nguyen, Thieu Long Phan +8
We present a hybrid multi-robot coordination framework that combines decentralized path planning with centralized conflict resolution. In our approach, each robot autonomously plan…
