Deep Volumetric Super‐Resolution Imaging in Thick Biological Specimens With Sparse Scanning SIM

Advanced Science, EarlyView.
Sparse scanning structured illumination microscopy (SS‐SIM) extends the axial depth in super‐resolution fluorescence imaging by combining rapid laser scanning, pixel‐addressed intensity modulation, and sCMOS camera detection. SS‐SIM yields 1.6× lateral and 1.7× axial resolution gains over wide‐field microscopy and enables imaging through 300–600 µm ...

Routing Optimization of Cable‐Driven Octopus‐Inspired Manipulators With Minimal Actuation via Genetic Algorithm and Finite Element Method

Advanced Intelligent Systems, EarlyView.
Soft robotic arms are promising for gentle grasping but often rely on bulky actuation systems. This work presents a computational design framework that optimizes tendon number and routing to achieve target grasps with fewer actuators. Validated on an octopus‐inspired underwater arm, the approach enables efficient, underactuated soft manipulators for ...

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
