Slip‐Adaptive Neural Control of Gecko‐Inspired Adhesive Robots
Advanced Intelligent Systems, EarlyView.This study introduces a neural adhesion controller to improve the stability of gecko‐inspired climbing robots. By integrating an echo state network and a multilayer perceptron, the system utilizes joint torque feedback to accurately estimate adhesion in both normal and shear directions and predict slips. This enables effective recovery from slip events,

Programmable‐Stiffness Tensegrity Continuum Robot for Adaptive Multicurvature On‐Orbit Assembly
Advanced Intelligent Systems, EarlyView.A bioinspired tensegrity‐based continuum robot (BTCR) with programmable stiffness enables adaptive multicurvature morphing via coordinated intra‐ and intermodule regulation. A unified energy‐based framework predicts self‐equilibrium and deformation for serial modules. Experiments and Simulations demonstrate reconfiguration into hexagonal, circular, and
