Sufficient conditions for log-concave conjecture on all-terminal reliability polynomial of a network

open access: yesSufficient conditions for log-concave conjecture on all-terminal reliability polynomial of a network
Consider a graph G that is simple, undirected, and connected, and has n vertices and m edges, and let Ni(G) denote the number of connected spanning i-edge-subgraphs in a graph G for an integer i(n-1■i■m). For a graph G and all integers i ’s (n■i■m-1), it is wellknown that the problem of computing all Ni(G) ’s is #P-complete (see e.g., [3, 7, 14, 31 ...

FiN‐Kiri: Fabric‐Based Inflatable Kirigami Actuator for Multimodal Soft Robots

open access: yesAdvanced Robotics Research, EarlyView.
This study introduces a type of inflatable fabric‐based kirigami actuator capable of performing bending motion. The actuator is utilized as soft grippers, a crawling robot and a swimming robot. The crawling robot demonstrated extraordinary motion capabilities, such as moving forward, turning and navigating a narrow tunnel.

Human‐Scale Rotating Magnetic Field Delivery With Permanent Magnets Under Anatomic and Robotic Constraints

open access: yesAdvanced Robotics Research, EarlyView.
Rotating magnetic fields (RMFs) are widely used for microrobot propulsion and control. We show that RMF generation with permanent magnets is mechanically feasible for many limb and intracranial applications but becomes constrained for thoracic targets.

Stiffness‐Programmable Origami Robots With Tendon‐Driven Actuation via Multimaterial 3D Printing

open access: yesAdvanced Robotics Research, EarlyView.
Motion diversity is achieved in a tendon‐driven origami robot through programmable stiffness rather than modified actuation. Multimaterial 3D printing embeds soft creases, modular inserts redirect identical tendon inputs into distinct behaviors, and variable‐stiffness inserts enable real‐time switching.
