Extended Seismic Source Characterisation using Linear Programming Inversion in a Dual Formulation [PDF]

, 2012
A linear programming (LP) inversion method in a dual formulation was applied to reconstruct the kinematics of finite seismic ruptures. In a general setting, this approach can yield results from several data sets: strong ground motion, teleseismic ...

Origami‐Inspired Structural Design for Aquatic‐Terrestrial Amphibious Robots

Advanced Robotics Research, EarlyView.
This work presents a lightweight amphibious origami robot actuated by a single shape memory alloy wire. A rigid foldable origami structure with displacement amplification enables efficient terrestrial crawling and aquatic swimming. The addition of fan‐shaped units allows controllable turning in both environments.

Study of Kinematic Calibration Method for Parallel Mechanism. (2nd Report). Kinematic Calibration Using Forward Kinematics.

Journal of the Japan Society for Precision Engineering, 2000
This paper describes a newly developed forward kinematic calibration method for parallel mechanisms which identifies the kinematic parameters using the pose data measured by a Double Ball Bar (DBB) system. The parameter identification procedure using forward kinematics does not require full pose data and, therefore, can make the measurement procedure ...

A Soft Robotic Fish With a Dielectric Elastomer Actuator Body and Negative Stiffness Spine

Advanced Robotics Research, EarlyView.
This work introduces a bio‐mimetic soft robotic fish driven by fiber‐reinforced dielectric elastomer actuators integrated as its body. By prestretching this active skin against a flexible spine, a negative stiffness system is created, enabling large‐amplitude bending.

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.

Kinematic and kinetic analysis during forward and backward walking

Gait & Posture, 2013
Backward walking (BW) is a recently emerging exercise. However, limited studies exist regarding the motion analysis of BW compared with that of forward walking (FW). The present study identified the mechanisms of BW through kinetic analysis and focused on BW time-reversed data.

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.
