Robotic Control for Human–Robot Collaborative Assembly Based on Digital Human Model and Reinforcement Learning

Advanced Robotics Research, EarlyView.
This work presents a robotic control method for human–robot collaborative assembly based on a biomechanics‐constrained digital human model. Reinforcement learning is used to generate physiologically plausible human motion trajectories, which are integrated into a virtual environment for robot control learning.

Multimodal Human–Robot Interaction Using Human Pose Estimation and Local Large Language Models

Advanced Robotics Research, EarlyView.
A multimodal human–robot interaction framework integrates human pose estimation (HPE) and a large language model (LLM) for gesture‐ and voice‐based robot control. Speech‐to‐text (STT) enables voice command interpretation, while a safety‐aware arbitration mechanism prioritizes gesture input for rapid intervention.

Detonation transition process in a channel equipped with the repeated obstacles (Effect of obstacle height and spacing on the DDT process)

Nihon Kikai Gakkai ronbunshu, 2016
Experiments were performed to investigate the deflagration-to-detonation transition (DDT) process in the channel equipped with repeated obstacles. A premixed gas of hydrogen-oxygen was ignited and the DDT process was visualized by using a high-speed ...
