A Precise Positioning Method for a Puncture Robot Based on a PSO-Optimized BP Neural Network Algorithm

Applied Sciences, 2017
The problem of inverse kinematics is fundamental in robot control. Many traditional inverse kinematics solutions, such as geometry, iteration, and algebraic methods, are inadequate in high-speed solutions and accurate positioning.

Particle kinematics in Hořava-Lifshitz gravity [PDF]

Journal of High Energy Physics, 2010
We study the deformed kinematics of point particles in the Horava theory of gravity. This is achieved by considering particles as the optical limit of fields with a generalized Klein-Gordon action. We derive the deformed geodesic equation and study in detail the cases of flat and spherically symmetric (Schwarzschild-like) spacetimes.

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.

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.

Higher-order soft and virtual corrections in $$p p \rightarrow \gamma W$$ p p → γ W production at the LHC

European Physical Journal C: Particles and Fields
We study higher-order QCD corrections beyond NLO for the associated production of a photon with a W boson ( $$\gamma W^+$$ γ W + and $$\gamma W^-$$ γ W - production) at the Large Hadron Collider. We calculate the NNLO soft-plus-virtual QCD corrections as

Hybrid Continuum Robot Designs and Architectures for Healthcare Applications

Advanced Robotics Research, EarlyView.
Hybrid continuum robots represent an emerging class of flexible manipulators that blend materials, structures, and actuation concepts from the established fields of soft and continuum robotics. This review introduces an accessible framework to distinguish key hybridization approaches, surveys current designs aimed at complex clinical applications, and ...

Quantifying influence of particle morphology during shallow indentation of a granular ensemble [PDF]

EPJ Web of Conferences
This study investigates the effect of particle shape on mechanical response of granular materials under shallow indentation. Two model materials at the same size but with vastly varying morphologies were used here.
