Advanced Intelligent Systems, EarlyView.This work presents a tip‐growing eversion robot that uses phase‐changing alloys for reversible stiffening and localized actuation, achieving 43× stiffness modulation, 15× force amplification, and segmental steering. The system enables precise navigation and force delivery in constrained, tortuous pathways.

Existence of vacuum wormholes in Einsteinian cubic gravity
Journal of High Energy PhysicsWormhole solutions in gravitational theories typically require exotic matter. Here we present a wormhole solution to the field equations of Einsteinian Cubic Gravity — a phenomenological competitor to general relativity that includes terms cubic in the ...

A Multimode Soft Robot Based on a Single Braided Tube
Advanced Intelligent Systems, EarlyView.This study introduces a novel soft multimode robot based on a single braided tube directly formed and actuated by SMA wires with distinct initial configurations. By combining contraction, elongation, and bending deformations, the robot achieves straight crawling, turning, inchworm crawling, and rolling without additional actuators.

Dynamics in canonical models of loop quantum gravity
, 2019 In this thesis we consider the problem of dynamics in canonical loop quantum gravity, primarily in the context of deparametrized models, in which a scalar field is taken as a physical time variable for the dynamics of the gravitational field. The dynamics of the quantum states of the gravitational field is then generated directly by a physical ...

Multimodal Locomotion of Soft Robots
Advanced Intelligent Systems, EarlyView.This review comprehensively surveys recent advances in multimodal locomotion within soft robotics. Typical locomotion modes are summarized and categorized. Furthermore, the underlying mechanisms enabling multimodal locomotion are discussed and classified into three primary categories: active control‐based, reconfiguration‐based, and environment ...

Contact Force Estimation of Continuum Robots without Embedded Sensors: A Review
Advanced Intelligent Systems, EarlyView.This review surveys methods for estimating contact forces in continuum robots without embedded sensors. It explains why contact force matters, classifies force patterns, and groups existing methods into three approaches based on actuation, deformation, and environment information.
