Disentangling Uncertainty for Safe Social Navigation using Deep Reinforcement Learning

IROS 2025

Autonomous mobile robots are increasingly used in pedestrian-rich environments where safe navigation and appropriate human interaction are crucial. While Deep Reinforcement Learning (DRL) enables socially integrated robot behavior, challenges persist in novel or perturbed scenarios to indicate when

Using a Collaborative Robotic Arm as Human-Machine Interface: System Setup and Application to Pose Control Tasks

ICRA 2023poster

While robotic arms have been used in a vast range of application areas, so far no extensive reports on the utilization as human-machine interface exist. Compared to HMI devices from literature, the robotic arm used in this work (KUKA LBR iiwa 14 R820) features a relatively large workspace and is abl…
