A Hybrid Magnetic Actuation System for Single‐Input Multistates Stabilization: Application to pH‐Responsive Drug Delivery

Advanced Intelligent Systems, EarlyView.
This study presents an integrated proof‐of‐concept robotic platform for targeted delivery applications. A hybrid magnetic actuation system achieves single‐input (z) multistate stabilization (x, y, ϕ, and θ) for precise capsule transport with submillimeter positioning accuracy.

Fast, Strong Capillary Liquid Metal Muscles

Advanced Intelligent Systems, EarlyView.
Capillary liquid metal muscles (CLMMs) harness the exceptionally high and electrochemically tunable surface tension of gallium‐based liquid metals (e.g., EGaIn) to generate mechanical work. Confinement within microchannels maximizes surface‐energy conversion, enabling high force, ultrafast response (<25 ms), low‐voltage operation (<10 V), and ...

3D Closed‐Loop Navigation of Magnetic Microswimmers Using Vision‐Derived Depth Feedback

Advanced Intelligent Systems, EarlyView.
A planar magnetic microswimmer is navigated in three dimensions under a standard microscope. Image defocus supplies a real‐time depth cue, and model‐predictive control with A* planning steers the body on surfaces and in free swimming. Axial position is regulated by propulsion alone, without magnetic field gradients or extra cameras.

Compliant Footpads Enable Terrain‐Adaptive Hopping in a Monopedal Robot

Advanced Intelligent Systems, EarlyView.
A lightweight compliant footpad with embedded spines lets a monopedal hopping robot keep stable ground contact. It preserves stance‐phase dynamics and enables reliable hopping on rock, sand, and ice. Monopedal hopping robots offer exceptional mobility over discontinuous terrain but require consistent foot‐ground contact to maintain stance‐phase ...
