Roll motion characteristics of a polar research ship with ice accumulation in beam waves

International Journal of Naval Architecture and Ocean Engineering
Stability of polar vessels could be deteriorated due to ice accumulation, making it crucial to investigate the dynamic behavior of the vessel under harsh polar conditions. In this work, the effect of ice accumulation on the roll motion characteristics of

Compliant Pneumatic Feet with Real‐Time Stiffness Adaptation for Humanoid Locomotion

Advanced Robotics Research, EarlyView.
A compliant pneumatic foot with real‐time variable stiffness enables humanoid robots to adapt to changing terrains. Using onboard vision and pressure control, the foot modulates stiffness within each gait cycle, reducing impact forces and improving balance. The design, cast in soft silicone with embedded air chambers and Kevlar wrapping, offers durable,

Muscle Control of an Extra Robotic Digit

Advanced Robotics Research, EarlyView.
This study compares muscle‐ and movement‐based control for operating a supernumerary robotic thumb. While movement control performs better in the proposed tasks, muscle‐based (EMG) control promotes broader motor learning. The results highlight the promise and challenges of using biosignals for human augmentation, offering new insights into intuitive ...

Experimental investigation into the roll damping characteristics of the intact and damaged ship in still water and ice floes

Applied Ocean Research
Ships face potential risks of damage from navigation environments and human factors. The multiphase flow of ship-water-ice particularly increases the difficulty of evaluating the roll damping characteristics of a damaged ship in ice floes.
