An Aerial Robot Achieving Bimodal Flight and Independent Attitude Control through Passive Morphing

open access: yesAdvanced Intelligent Systems, EarlyView.
This article presents a bimodal aerial robot capable of operating in both standard quadcopter and revolving flight modes. With four rotors, it independently controls position and roll‐pitch attitude across five degrees of freedom. The design features passive revolute joints, allowing seamless mid‐air transitions between modes using centrifugal forces ...

Black and minority ethnic student teachers' stories as empirical documents of hidden oppressions: Using the personal to turn towards the structural

open access: yesBritish Educational Research Journal, Volume 48, Issue 6, Page 1145-1160, December 2022., 2022
Abstract Racism, as a covert but pervasive presence in teacher education in England, remains a major structural issue and its effects on student teachers who are Black and Asian are real and troubling. Their personal stories reveal multiple challenges and present empirical evidence that can usefully be analysed to examine their experience of daily ...

Exploring natural variation in tendon constitutive parameters via Bayesian data selection and mixed effects models [PDF]

open access: yesarXiv
Combining microstructural mechanical models with experimental data enhances our understanding of the mechanics of soft tissue, such as tendons. In previous work, a Bayesian framework was used to infer constitutive parameters from uniaxial stress-strain experiments on horse tendons, specifically the superficial digital flexor tendon (SDFT) and common ...

Effect of tendon structural control on the appearance of horseshoes chaos on a cantilever beam due to seismic action [PDF]

open access: yesarXiv, 2017
This paper deals with the problem of improving the seismic strength of mechanical structures by using a tendon system as actuation device. It consists of a pair of tension cables transmitting a control torque to the structure at the moment arm position.

Toward Dynamic Control of Tendon-Driven Continuum Robots using Clarke Transform [PDF]

open access: yesarXiv
In this paper, we propose a dynamic model and control framework for tendon-driven continuum robots with multiple segments and an arbitrary number of tendons per segment. Our approach leverages the Clarke transform, the Euler-Lagrange formalism, and the piecewise constant curvature assumption to formulate a dynamic model on a two-dimensional manifold ...

Deep Learning Methods in Soft Robotics: Architectures and Applications

open access: yesAdvanced Intelligent Systems, EarlyView.
Soft robotics has seen intense research over the past two decades and offers a promising approach for future robotic applications. However, standard industrial methods may be challenging to apply to soft robots. Recent advances in deep learning provide powerful tools to analyze and design complex soft machines that can operate in unstructured ...
