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

Spatial Aggregation of Complex Terrain [PDF]
Geographical Analysis, 1989 Distributed component simulations of watersheds seek to represent the terrain as a contiguous set of functional units such as hillslopes or subcatchments with distinctive hydrologic responses. The partition should capture the significant geographic patterns of watershed response by maximizing the proportion of the topographic and surface cover variance

Advanced Robotics Research, EarlyView.WorMa is an amphibious undulatory robot that uses Center of Mass redistribution as the sole terrain adaptation mechanism. This mechanism is based on internal fluid mass redistribution through a pump‐driven latex balloon system that creates three profiles: head‐biased, balanced, and tail‐biased.

Toward Mechanical Intelligence in Robotics
Advanced Robotics Research, EarlyView.Robots can use their physical bodies to perform functions usually assigned to electronic sensors and controllers. This perspective defines mechanical intelligence through three core operations: filtering inputs, routing mechanical signals, and switching between states.
