This paper presents a novel Quantum Gravity Theory (QGT) that reinterprets the gravitational field as being derived from the Higgs field within a flat spacetime framework. Unlike General Relativity (GR), which attributes gravity to spacetime curvature, QGT integrates quantum corrections, nonlinear dynamics, and a variable speed of lightto describe ...

Treecreeper Drone: Adaptive Mechanism for Passive Tree Trunk Perching
Advanced Intelligent Systems, EarlyView.Taking inspiration from treecreepers, a passively triggered aerial robot that can reliably perch on vertical tree trunks is presented. The friction‐based approach combines a microspine array with a tail‐like support, and then validates via dynamic analyses and flight experiments, ensuring stable performance across trunk diameters and bark textures ...

Advanced Intelligent Systems, EarlyView.This review explores invertebrate biohybrid robots that integrate living organisms—such as insects, jellyfish, spiders, and sea slugs—into robotic systems for locomotion, sensing, and actuation. The advantages in efficiency and cost, discuss control, and power challenges are highlighted, and future considerations to guide the development of sustainable,

Advanced Intelligent Systems, EarlyView.Liquid metal “sloshing” by the robot's own actuator is proposed to improve the self‐healing performance. The proposed method drastically enhances the healed strength by decomposing the surface oxides and the impurities. The method contributes to the world's first demonstration of active self‐healing behavior performed by a life‐sized legged robot. Self‐

Advanced Intelligent Systems, EarlyView.A passive, tunable perching mechanism enables aerial robots to reliably perch onto smooth surfaces. The design integrates a bistable mechanism with a soft suction cup and SMA actuators for active tuning. Experiments demonstrate robust performance by adapting to varying contact speeds and surface orientation misalignments, enabling diverse perching ...

Thermally Responsive Architected Actuators with Programmable Shape Morphing and Tunable Stiffness
Advanced Intelligent Systems, EarlyView.A tunable‐stiffness architected morphing structure enables programmable shape transformation and load‐bearing functionality through thermal activation. By tessellating rigid particles with shape memory alloy‐based soft connectors, the system achieves simultaneous morphing and stiffness modulation.
