moving obstacle avoidance matlab code

Introduction

This example demonstrates an implementation of the VFH+ obstacle avoidance algorithm with the TurtleBot . The use of timers is explored to expose their power in autonomous algorithms.The VFH+ algorithm is a simple, local method to help a robot navigate a space without hitting obstacles. Because the algorithm incorporates only local information, the robot is not guaranteed to reach the target point. It can get stuck in corners (local minimum). It can hit walls if the goal targeting gain is to ....etc

Eun-Young Park*, Woon-Sung Lee**, and Jung-Ha Kim**
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 un ....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

Fuzzy Logic and Fuzzy Sets


History

Lotfi Zadeh, at the University of California at Berkeley, first presented fuzzy logic in the mid-1960's.

Zadeh developed fuzzy logic as a way of processing data. Instead of requiring a data element to be either a member or non-member of a set, he introduced the idea of partial set membership.

In 1974 Mamdani and Assilian used fuzzy logic to regulate a steam engine.

In 1985 researchers at Bell laboratories developed the first fuzz ....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 algorithm is that,by va ....etc
