Space Geodetic Imaging of Rapid Ground Subsidence in Mexico City

open access: yes, 2008
Since the late 1950s, several areas of Mexico City have undergone accelerated ground subsidence and have developed associated fracturing and faulting. New interferometric synthetic aperture radar (InSAR) and global positioning system (GPS) data indicate ...

Compliant Pneumatic Feet with Real‐Time Stiffness Adaptation for Humanoid Locomotion

open access: yesAdvanced Robotics Research, EarlyView.
A compliant pneumatic foot with real‐time variable stiffness enables humanoid robots to adapt to changing terrains. Using onboard vision and pressure control, the foot modulates stiffness within each gait cycle, reducing impact forces and improving balance. The design, cast in soft silicone with embedded air chambers and Kevlar wrapping, offers durable,

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

open access: yesAdvanced 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.

A Hybrid Ground Subsidence Prediction Model for Airport Pavement Management [PDF]

open access: yes
The estimation of ground subsidence processes is an important subject for the asset management of airport facilities. In the planning and design stage, there exist many uncertainties in geotechnical conditions, it is impossible to estimate the ground ...

Intelligent Sky Guardians (InSkyGuard): An Aerial Robotic Swarm for Autonomous Detection and Entrapment of Rogue Multirotors

open access: yesAdvanced Robotics Research, EarlyView.
Intelligent Sky Guardians (InSkyGuard) is introduced as a four‐drone swarm that autonomously detects, tracks, and safely captures rogue drones using a coordinated net system. Computer vision and leader–follower control architecture enable synchronized enclosure, while integrated failsafes enhance system reliability. Validated through closed‐environment

Prediction of Bending Moment of a Batter Pile in Subsiding Ground

open access: yesSoils and Foundations, 1989
ABSTRACT Prediction of bending moments of a batter pile installed in subsiding clay ground is presented. The analysis is based on the assumption that loads acting on the upper part of a pile are similar to the case of a positive project conduit and the lower part of the pile behaves as an elastic beam on Winkler’s model.

Continuum Robots in Surgery: From Engineering Design to Clinical Practice

open access: yesAdvanced 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.

Origami‐Inspired Morphing Fuselage for Agile Fixed‐Wing Flight

open access: yesAdvanced 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 ...
