This study provides both a spherical understanding about autonomous ship navigation for collision avoidance (CA) and a theoretical background of the reviewed work. Additionally, the human cognitive abilities and the collision avoidance regulations (COLREGs) for ship navigation are examined together with water based collision avoidance by: In an imminent crash situation, an autonomous vehicle is expected to consider these costs and plan a trajectory that avoids the obstacles with the highest priorities. In this thesis, a motion planning Model Predictive Controller (MPC) has been developed that plans the vehicle’s trajectories based on the obstacle’s priorities. Motion Cited by: 1.

A summary of this report entitled "ALX: Autonomous Vehicle Guidance for Roadway Following and Obstacle Avoidance" was presented at the IEEE Systems, Man and Cybernetics Conference, Vancouver, British Columbia, and is contained in the proceedings (pp.

A robot or micro controller can perform maneuvers to avoid obstacles according to the measured signal from those sensors. Therefore it is easy to File Size: KB.

The first field where it was researched is robotics(9,11,20,28,29). With the advent of UAVs, and the increasing desire for autonomous UAVs, robotic obstacle avoidance methods were employed for UAVs (1,18,35).

However, because UAVs and. However, many of the lower-end UAV do not have obstacle avoidance systems installed, which can lead to broken equipment or people may get injured.
