Abstract
Laser obstacle sensors are undergoing development at a very fast pace.These are the most accurate among distance sensors but their high costs on account of not so easily available materials used in their construc- tion delayed their deployment for commercial applicat ....etc

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 measurements concerning the obstacl ....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

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

Abstract
A SEA Swarm (Sensor Equipped Aquatic Swarm) isa collection of mobile underwater sensors that moves as a groupwith water current and enables 4D (space and time) monitoringof local underwater events such as contaminants and intruders.For prompt alert reporting, mobile sensors routes events to mobilesinks (i.e., autonomous underwater vehicles) via geographicrouting that is known to be most efficient under mobility andscarce acoustic bandwidth. In order for a packet to be routed tothe destination using geographical routing, it req ....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

this project is for designing a Obstacle Detector , Now with video of the sensor being used as a Mintvelt inspired object tracker! This sensor is a short range obstacle detector with no dead zone. It has a reasonably narrow detection area which can be increased using the dual version. Range can also be increased by increasing the power to the IR LEDs or adding more IR LEDs

IR LED's as a light source and two phototransistors in parallel for the reciever. You could use one of each .This setup works like a FritsLDR but with IR. It has a ran ....etc
