Torque‐Transmitting Architected Metamaterials for Flexible and Extendable Tubular Robotics

Advanced Intelligent Systems, EarlyView.
Soft and continuum robots commonly rely on fluid, tendon, or rod‐based power transmissions, to control robotic form and actuation. This study presents an architected structure, based on patterned straight‐line mechanisms, that enables simultaneous bending, extending, and torsionally rigid (BETR) transmission.

Real‐Time Control of a Humanoid Robot for Whole‐Body Tactile Interaction

Advanced Intelligent Systems, EarlyView.
Inspired by human tactile interaction, this work integrates large‐area artificial skin feedback (force and proximity) into real‐time quadratic programming control for humanoids. This enables robots to leverage distributed sensing to manage forces, safely move around unknown and dynamic obstacles, and robustly handle objects with uncertain geometry ...

Robotic Interventional Needle Insertion Assisted by a Cable‐Driven Parallel Robot

Advanced Intelligent Systems, EarlyView.
This article presents a body‐mounted cable‐driven parallel robot assisting the needle insertion procedure designated for automated interventional pain therapy. The 3D‐printed robot body and multiple thin cables can achieve high X‐ray compatibility for intervention. The robot performs full 6‐degree of freedom needle insertion and remote center of motion

A Memristive Associative Learning Circuit for Fault‐Tolerant Multi‐Sensor Fusion in Autonomous Vehicles

Advanced Intelligent Systems, EarlyView.
A memristor‐based associative learning circuit is presented for real‐time, fault‐tolerant sensor fusion in autonomous systems. The circuit mimics biological learning to recognize driving scenarios even with missing or degraded sensor inputs. Its low‐power, analog architecture enables robust decision‐making across diverse conditions, offering a ...
