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

hai sir..,
I m v.vanitha studing b.tech 3rd year . I want to know about the obstacle avoidance and manhole detection for the blind people by using with and without sensors and also the block diagram regarding this topic.

Thanking you,

yours faithfully,
v.vanitha
please say me about sensors used in manhole detection for blind people..............etc

Obstacles Avoidance Method for an Autonomous Mobile Robot using
Two IR Sensors

Abstract:
The paper presents a local navigation
method for mobile robot, based on sensorial information
given by two IR sensors. These types of sensors are
simple and relatively low-cost sensing modalities to
perform navigation tasks in environments with obstacles.
On the other hand, IR sensors may be preferable due to
their faster response time and can be integrated in
structure with microcontroller.

EDGE Compact and EDGE Classic Packet Data Performance
Abstract
Even though cellular radio services have been extremely successful in providing untethered voice communications, wireless data services have captured only a limited market share so far. One obstacle for wireless data services is their limited peak bit rates. Existing wireless data rates, up to several tens of kb/s, may be over one order of magnitude short o..............etc

Even though cellular radio services have been extremely successful in providing untethered voice communications, wireless data services have captured only a limited market share so far. One obstacle for wireless data services is their limited peak bit rates. Existing wireless data rates, up to several tens of kb/s, may be over one order of magnitude short of what is required to make popular applications user-friendly. To accomplish these necessities we go for ..............etc
