Untethered Autonomous Holonomic Mobile Micromanipulator for Operations in Isolated Confined Spaces

open access: yesAdvanced Intelligent Systems, EarlyView.
Herein, a lightweight (515 g), compact (10 cm3), untethered holonomic mobile micromanipulator powered by piezoelectric actuators is presented. It autonomously manipulates mm to sub‐mm objects and droplets in narrow, hazardous spaces, achieving 0.18 ± 0.51 mm positioning accuracy and −0.4° ± 1.2° angular deviation.

Self‐Rhythmic Soft Pneumatic Pressure Regulation System Based on Self‐Excited Oscillation of Jet Hose

open access: yesAdvanced Intelligent Systems, EarlyView.
This study presents a soft pneumatic pressure regulation system that uses self‐excited hose oscillations to convert constant pressure (90–150 kPa) into rhythmic output. Simulations and experiments demonstrate tunable oscillation frequencies (5.9–11.1 Hz) through adjustments in pressure, hose length, and jet hole diameter.

Decreasing the Cost of Morphing in Adaptive Morphogenetic Robots

open access: yesAdvanced Intelligent Systems, EarlyView.
Shape‐morphing propulsive limbs enhance locomotion across land‐to‐water transitions, but prior designs rely on thermally responsive components, coupling performance to environmental temperature. This study introduces a pressure‐responsive mechanism that reduces morphing energy costs, enables rapid transitions, and minimizes failure modes.

A Synthesized Neural Control System for Bioinspired Robots to Achieve Diverse Locomotion

open access: yesAdvanced Intelligent Systems, EarlyView.
A novel hexapod robot named RENS H2 based on the synthesized neural control system. The control system is constructed based on the central pattern generator and virtual motoneurons network, serving as the foundation of the behavioral network. It encompasses omnidirectional movement, regulation of motor neuron intensity, sensorimotor integration, local ...
