Multimodal Actuation and Environment Adaptive Strategies of Bio‐Inspired Micro/Nanorobots in Precision Medicine

open access: yesAdvanced Robotics Research, EarlyView.
An introduction for multidrive and environment‐adaptive micro/nanorobotics: design and fabrication strategies, intelligent actuation, and their applications. Various intelligent actuation approaches—magnetic, acoustic, optical, chemical, and biological—can be synergistically designed to enhance flexibility and adaptive behavior for precision medicine ...

Nonlocomotory Robotic Strategies for Dynamic Rotation Control in Terrestrial Robots: A Review

open access: yesAdvanced Robotics Research, EarlyView.
Terrestrial robots increasingly require rapid body rotation to maintain stability and agility in complex environments. This review shows nonlocomotory rotational control strategies that operate without ground contact, including reaction wheels, tails, bars, limbs, and thrusters.

Deformation and Dynamic Response Analysis of Metro Shield Tunnel Under-Crossing Existing Railway Frame Bridge

open access: yesChengshi guidao jiaotong yanjiu
[Objective] At present, there are few studies on the interaction between the under-crossing shield and the upper vehicle-track structure. In order to ensure the safety of new metro shield construction and existing line operation, it is necessary to ...

Tumbling Magnetic Microrobots for Targeted In Vivo Drug Delivery in the GI Tract

open access: yesAdvanced Robotics Research, EarlyView.
We introduce a microrobot design and integrated system for on‐demand targeted drug release in the gastrointestinal tract. The microrobot has an embedded magnet for actuation with external magnetic fields and is visualized in real time using ultrasound. It has two drug release ports sealed with a thermally sensitive wax. Local heating of the wax using a

Adjacent Construction Impact of Shield Tunnel Undercrossing High-Speed Railway Tunnels Based on Surrounding Rock Creep Effect

open access: yesChengshi guidao jiaotong yanjiu
[Objective] When the surrounding rock exhibits creep characteristics, the temporal factors in the adjacent construction process of shield tunnel undercrossing high-speed railway tunnels cannot be ignored. The speed of the adjacent construction may affect

A State‐Adaptive Koopman Control Framework for Real‐Time Deformable Tool Manipulation in Robotic Environmental Swabbing

open access: yesAdvanced Robotics Research, EarlyView.
This work presents a state‐adaptive Koopman linear quadratic regulator framework for real‐time manipulation of a deformable swab tool in robotic environmental sampling. By combining Koopman linearization, tactile sensing, and centroid‐based force regulation, the system maintains stable contact forces and high coverage across flat and inclined surfaces.

Structural Health Monitoring of Railway Transition Zones Using Satellite Radar Data

open access: yesSensors, 2018
Transition zones in railway tracks are locations with considerable changes in the rail-supporting structure. Typically, they are located near engineering structures, such as bridges, culverts and tunnels.
