Introduction

Obstacle detection and avoidance robots are intelligent robots which can perform desired tasks in unstructured environments by finding and overcoming obstacles in their way without continuous human guidance.
In robotics, obstacle avoidance is the task of satisfying some control objective subject to non-intersection or non-collision position constraints. Normally obstacle avoidance is considered to be distinct from path planning in that one is usually implemented as a reactive c ....etc

Use of A algorithm for obstacle avoidance

Abstract
A* algorithm is basically a path finding algorithm based on Artificial Intelligence. It is used nowadays extensively in the field of game programming and robotics to figure out an optimum path in an environment full of obstacles. The A* algorithm can be used in both 2-D and 3-D terrain. Each terrain is represented as a map. The beauty of the a ....etc

Abstract:
In this research, we will devise an obstacle avoidance algorithm for a previously unmanned vehicle. Whole systems consist mainly of the vehicle system and the control system. The two systems are separated; this system can communicate with the vehicle system and the control system through wireless RF (Radio Frequency) modules. These modules use wireless communication. And the vehicle system is operated on PIC Micro Controller. Obstacle avoidance method for u ....etc

Real-Time Obstacle Avoidance

Introduction
Real-time obstacle avoidance is one of the key issues to successful applications of mobile robot systems. All mobile robots feature some kind of collision avoidance, ranging from primitive algorithms that detect an obstacle and stop the robot short of it in order to avoid a collision, through sophisticated algorithms, that enable the robot to detour obstacles. The latter algorithms are much more complex, since they involve not only the detection of an obstacle, but also some kind of quantitative mea ....etc
