Continuum Robots in Surgery: From Engineering Design to Clinical Practice

Advanced Robotics Research, EarlyView.
The hyper‐redundant nature of continuum robot structures enables near‐infinite degrees of freedom leading to immense potential for medical applications. This review provides a historical background of continuum robots and novel ideas shaping their progress to current structural design, sensing technology, modeling techniques, and control methods.

Ultrasound elastography for imaging tendons and muscles

Journal of Ultrasonography, 2012
Ultrasound elastography is a recently developed ultrasound-based method which allows the qualitative or quantitative evaluation of the mechanical properties of tissue. Strain (compression) ultrasound elastography is the commonest technique performed by

Stiffness‐Programmable Origami Robots With Tendon‐Driven Actuation via Multimaterial 3D Printing

Advanced Robotics Research, EarlyView.
Motion diversity is achieved in a tendon‐driven origami robot through programmable stiffness rather than modified actuation. Multimaterial 3D printing embeds soft creases, modular inserts redirect identical tendon inputs into distinct behaviors, and variable‐stiffness inserts enable real‐time switching.

Vascularity of tendons.

, 2013
There was reduced vascularity in the MSC-treated tendons, similar to normal tendon, compared to saline-injected controls. * p = 0.026; ** p = 0.004.

Toward Mechanical Intelligence in Robotics

Advanced Robotics Research, EarlyView.
Robots can use their physical bodies to perform functions usually assigned to electronic sensors and controllers. This perspective defines mechanical intelligence through three core operations: filtering inputs, routing mechanical signals, and switching between states.

A Transnasal Endoscope for Robotically Assisted Gastroscopy

Advanced Robotics Research, EarlyView.
This work introduces a 4.25 mm diameter magnetically navigated transnasal endoscope for upper gastrointestinal (GI) screening and intervention. The system enables precise remote steering throughout the upper GI tract and is demonstrated through in vitro and in vivo experiments, including the robotic execution of preprogrammed retroflexions, trans ...

Origami‐Inspired Morphing Fuselage for Agile Fixed‐Wing Flight

Advanced Robotics Research, EarlyView.
Conventional aircraft steer with rigid control surfaces. SoAR instead replaces the fuselage itself with a cable‐driven origami continuum body that bends in 3D and compresses on demand. Whole‐fuselage morphing steers fixed‐wing flight: achieving sharp, near‐zero‐radius turns and rapid braking without ailerons, rudder, or elevator, while the same ...

Shear‐Isolating Actuation System for Exosuit Using Movable Pulley With Webbing‐Driven Mechanism

Advanced Robotics Research, EarlyView.
Tendon‐driven exosuits can chafe the skin because the moving tendon slides against the wearer. A shear‐isolating actuation system combining a movable pulley with flat‐profile webbing keeps the body‐contacting tendon layer stationary, relocating relative motion away from the skin. The compact 145‐g actuator delivers 150 N of assistance, and benchtop and

Sonography of pathological changes in the hand

Journal of Ultrasonography, 2014
Everyday medical practice shows that most common problems within the hand result from overload, injuries and degeneration. Dorsal side pathologies such as de Quervain’s and Wartenberg’s disease, intersection syndrome or degenerative lesions of ...
