Miniaturized Magnetic Tip Design for Endoluminal Vine Robot Navigation

Advanced Robotics Research, EarlyView.
A magnetic tip mount is designed for a miniaturized 7 mm soft‐growing vine robot to enable wireless magnetic steering and onboard imaging, while preserving a 3 mm working channel. The internal–external ring magnets design balances magnetic attachment with low eversion pressure. Experiments demonstrate ±90° steering, 34 mm bending radius, and successful

Wind-constrained Pareto multi-objective reinforcement learning for low-carbon vessel traffic organization in port approach channels

Frontiers in Marine Science
Port approach channels concentrate vessel conflicts, waiting, and speed adjustments that can increase fuel use and CO2 emissions, yet real-time wind is rarely represented as both an emission driver and a scheduling constraint.

A Study on Local Traffic Management to Improve Marine Traffic Safety in the Istanbul Strait

, 2011
The Istanbul Strait is one of the most congested waterways in the world and is difficult to navigate due to its ‘S-shaped’ geographic structure (Akten, 2004). Much of the local marine traffic affects navigation safety. Results of Yurtoren and Inoue (2004)
