Safety Navigation of High Speed Craft at Congested Sea Area

Performance Analysis and Prediction of High Speed Planing Craft

A comprehensive and critical review of literature pertaining to the study of planing craft is given within this work. This study includes monohull design, analysis and performance prediction for flat water; many features of the planing characteristics, including dynamic stability, the use of stepped hullforms, re-entrant transoms and flow characteristics are detailed. Work on the rough water se...

WIG-craft Marine Landing Control at Rough Sea

Wing-in-Ground Effect vehicle (WIG-craft) or ekranoplane landing direction optimization criteria is suggested which heeds the irregular sea waves features and provides the minimal mechanical strain on the vehicle body at hydrodynamic braking. The problem of automatic choice of the landing trajectory direction regarding the main direction of sea waves spread is under consideration. The peculiari...

Potential Field Navigation of High Speed

This paper proposes a potential field-based method for high speed navigation of unmanned ground vehicles (UGVs) on uneven terrain. A potential field is generated in the two-dimensional “trajectory space” of the UGV path curvature and longitudinal velocity. Dynamic constraints, terrain conditions, and navigation conditions can be expressed in this space. A maneuver is chosen within a set of perf...

High Speed Neural Control for Robot Navigation

This work addresses the real time control of the Khepera mobile robot [1] navigation in a maze with reflector walls. Boolean Neural Networks such as RAM [2] and GSN [3] models are applied to drive the vehicle, following a light source, while avoiding obstacles. Both neural networks are implemented with simple logic and arithmetic functions (NOT, AND, OR, Addition, and Comparison), aiming to imp...
