Beyond Fixed Goal Delivery: Online POMDP Planning for Target Interception in Crowds
Himanshu Gupta, Kelvin Aladum, Nisar Ahmed +2
Target interception in crowded environments requires reaching a moving objective while navigating among multiple uncertain human agents. Since human navigation intent is not direct…
Environment Design for Reliable Shared Autonomy with Probabilistic Guarantees
Yi-Shiuan Tung, Himanshu Gupta, Gyanig Kumar +3
Shared autonomy enables humans and robots to collaboratively perform tasks by combining human input with autonomous assistance. Most prior work focuses on improving intent inferenc…
Risk-Aware Preference Learning for Stochastic Outcomes
Yi-Shiuan Tung, Yuni Wu, Wei Jiang +2
Learning reward functions from human preferences is a widely used approach for aligning robot behavior with user expectations in human-robot interaction. Most existing approaches a…
CRED: Counterfactual Reasoning and Environment Design for Active Preference Learning
Yi-Shiuan Tung, Gyanig Kumar, Wei Jiang +2
As a robot's operational environment and tasks to perform within it grow in complexity, the explicit specification and balancing of optimization objectives to achieve a preferred b…
Employing Laban Shape for Generating Emotionally and Functionally Expressive Trajectories in Robotic Manipulators
Srikrishna Bangalore Raghu, Clare Lohrmann, Akshay Bakshi +4
Successful human-robot collaboration depends on cohesive communication and a precise understanding of the robot's abilities, goals, and constraints. While robotic manipulators offe…
