Autonomous Ship Safe Navigation using Smoothing A* Algorithm
Using reasonable and efficient autonomous technology for path planning can effectively improve the safety of ship navigation and can reduce human errors of maritime accidents. The planned path by A* algorithm is flawed with broken lines, many turning points and numerous transitional frequencies under the environment modeled by grid method. Smoothing A* algorithm is adopted to delete the removab...
متن کاملA Navigation System for Autonomous Robot Operating in Unknown and Dynamic Environment: Escaping Algorithm
In this study, the problem of navigation in dynamic and unknown environment is investigated and a navigation method based on force field approach is suggested. It is assumed that the robot performs navigation in...
متن کاملSafe Navigation of Mobile Robot Using A* Algorithm
Path planning contributes a very significant role in navigation of a mobile robot. The accuracy of path depends on mapping and localization of an indoor environment. A number of path planning approach are already in applications like A* Algorithms, D* Algorithm (Heuristic Approach), Dijkstra’s Algorithm (Deterministic approach), Cell Decomposition Technique etc. The conventional A* algorithm me...
متن کاملShip to Ship Maritime Communication for e-Navigation Using WiMAX
Maritime wireless communication is different from terrestrial wireless communication, due to difference of environments. Nevertheless technologies based on WiMAX (IEEE 802.16j) for ship to ship maritime communication promised to deliver high data rates over large distances and deliver multimedia services and are expected to use e-Navigation system. This paper focuses to simulate on IEEE 802.16j...
متن کاملAutonomous Ship-board Landing using Monocular Vision
This paper describes a system for landing a vertical take-off and landing vehicle on a moving deck using a monocular vision system and inertial measurement unit. Data from the vision system and IMU are used to compute an estimate of relative deck position, and a touchdown trajectory generator based on tau-guidance is used to compute a path to landing. A trajectory-following controller follows t...
