An Origami‐Inspired Cable‐Driven Continuum Robot

Advanced Intelligent Systems, EarlyView.
A cable‐driven origami‐inspired continuum robot with dual bending‐contraction freedom is presented, overcoming monofunctional limitations of existing designs. A multijoint prototype demonstrates significant adaptability for shape‐variable grasping. Embedded structural conformality further supports a customizable wrist orthosis with dual rehabilitation ...

Planning and Control Framework for a Quadruped Robot With Changeable Configuration

Advanced Intelligent Systems, EarlyView.
Multiconfiguration quadruped robots enhance adaptability by switching between mammal‐like and reptile‐like morphologies. This study presents a nonlinear constraint‐based motion planner integrated with a hierarchical whole‐body controller, enabling robust configuration switching and locomotion on complex terrains. Experiments on slopes, irregular bricks,

BeeRootBot: A Bioinspired Robotic Probe Exhibiting Apical Growth through In Situ Soil Binding

Advanced Intelligent Systems, EarlyView.
This study introduces a novel method for consolidating subterranean exploration pathways in plant‐inspired robots by binding in‐situ soil with beeswax, a biobased material. This simultaneous advancement and wall‐lining process reduces penetration resistance, enhances exploration efficiency, enables communication and resource sharing, and promotes ...
