A Reinforcement Learning Framework for Safety-Aware Haptic Shared Control in Surgical Robotics
Zihao Zhang, Karl Handwerker, Balint Varga
Haptic shared control in surgical robotics combines human-side and robot-side forces at a shared end effector while preserving operator involvement. However, the effects of geometr…
Approximate Feedback Nash Equilibria in Constrained Differential Games via Model Predictive Control with Upper Bound Guarantees
Balint Varga, Karl Handwerker, Imre Rudas +1
Physical human--machine interaction and other multi-agent control settings require decision-making policies that adapt online. Differential games provide a principled framework whe…
Policy Iteration for Linear-Quadratic Stochastic Differential Games with State- and Control-Dependent Noise
Karl Handwerker, Felix Thömmes, Lucas Günther +2
This paper presents a novel sequential policy iteration (PI) method for stochastic differential games with state- and control-dependent noise. The updates preserve mean-square stab…
Infinite-Horizon Inverse Linear-Quadratic Differential Games with State- and Control-Dependent Noise
Lucas Günther, Karl Handwerker, Felix Thömmes +2
This paper presents a method to solve the inverse problem for N-player infinite-horizon linear-quadratic (LQ) differential games with state- and control-dependent noise. For this s…
Locomotion Variability and User Experience in Smart Wheelchair Human-Robot Interaction
Sean Kille, Adina M. Panchea, Balint Varga +1
Human movement is inherently variable, with variability structured according to task relevance: movements are typically more consistent at task-critical points and more flexible el…
The Role of Variability in Human-Machine Interaction Experience
Sean Kille, Jan Lars Hagemann, Anne Voormann +3
Human-machine interaction (HMI) requires control strategies that account for the nature of human motor behavior. Conventional shared-control and haptic-assistance methods typically…
