The automotive industry is motivated to provide more and more amenities to its customers. The industry is taking advantage of artificial intelligence by increasing different sensors and gadgets in vehicles machoism is forward collision warning, at the same time road accidents are also increasing which is another concern to address. So there is an urgent need to provide an A.I based system to avoid such incidents which can be address by using artificial intelligence and global positioning system. Automotive/smart vehicles protection has become a major study of research for customers, government and also automotive industry engineers In this study a two layered novel hypothetical approach is proposed which include in-time vehicle/obstacle detection with auto warning mechanism for collision detection & avoidance and later in a case of an accident manifestation GPS & video camera based alerts system and interrupt generation to nearby ambulance or rescue-services units for in-time driver rescue.

A neural optimization network is proposed to control the redundant robot manipulators in an environment with the obstacle. The weightings of the network are adjusted by considering both the joint dexterity and the capability of collision avoidance of joint differential motion. The fuzzy rules are proposed to determine the capability of collision avoidance of each joint. To show the validities of the proposed method, computer simulation results are illustrated for the redundant robot of the planner type with three degrees of freedom.

AIS를 이용한 선박간의 자동위치인식이 적용되고 있으나 여전히 많은 선박사고로 인해 인명 및 재산 손실 뿐만 아니라 환경오염까지 초래하는 문제가 발생하고 있다. 이에 본 논문에서는 선박사고 중 높은 사고율을 차지하는 선박간의 충돌사고를 줄이고자 AIS에서 제공하는 static 정보, dynamic 정보를 이용하여 선박 충돌 회피 알고리즘과 시뮬레이션 시스템 설계를 제시한다.

This paper investigates the possibility of applying fuzzy algorithms to the collision avoidance problem of a cylindrical robot moving in a 3-dimensional workspace. The displacement information from the end-effector to the points via which the robot can avoid collisions is given by the human operator. Then this uncertain information is adopted for the fuzzy inference system for robot movements. The robot movement is simulated to verify the effectiveness of the proposed fuzzy algorithm.

In this paper, we propose an inference method for understanding intention of obstacle for collision avoidance using the grid-type map. In order to represent the environment using ultrasonic sensors, the grid-type map is first constructed. Then we detect the obstacle and infer the intention for collision avoidance using the CLA(Centroid of Largest Area) point of the grid-type map. To verify the proposed method, some experiments are performed.

In this paper, we propose a space partitioning technique for swarm robots by using the Centroidal Voronoi Tessellation. The proposed method consists of two parts such as space partition and collision avoidance. The space partition for searching a given space is carried out by a density function which is generated by some accidents. The collision avoidance is implemented by the potential field method. Finally, the numerical experiments show the effectiveness and feasibility of the proposed method.

A genetic algorithm for global and local path planning and collision avoidance of mobil robot in unstructured workspace is proposed. The genetic algorithm searches for a path in the entire and continuous free space and unifies global path planning and local path planning. The simulation shows the proposed method is an efficient and effective method when compared with the traditional collision avoidance algorithms.

An avoidance/guidance problem of an aircraft against moving obstacle is considered in two dimensional space. The aircraft is modelled as a point mass flying with constant speed. The lateral acceleration is assumed the control input. Artificial potential functions are applied to the terminal point and moving obstacles in order that repulsive forces and an attractive force are produced by the obstacles and the terminal point respectively. A real time guidance/avoidance law is proposed by using the potential forces and relative velocity. The guidance law for a logarithm potential function results the well-known proportional navigation law. The avoidance control command is inverse proportional to the time-to-go to the obstacle and turns the aircraft toward the negative direction of the line-of-sight change. The performance of the proposed guidance/avoidance law is verified with simulations.
