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

Blind stick is an innovative stick designed for visually disabled people for improved navigation. We here propose an advanced blind stick that allows visually challenged people to navigate with ease using advanced technology. The blind stick is integrated with ultrasonic sensor along with light and water sensing. Our proposed project first uses ultrasonic sensors to detect obstacles ahead using ultrasonic waves. On sensing obstacles the sensor passes this data to the microcontroller. The microcontroller then processes this data and calculates i ....etc

MICROCONTROLLER BASED WALKING AID FOR BLIND & DEAF

Abstract
Biomedical engineering specializes in making life easier for the physically challenged. Our project is an endeavor in this direction. IR sensor mounted on to the stick is used for detecting obstacles in the path of the user and a vibrational feedback is provided which is decided by microcontroller. The same circuit is mounted on a cap for detecting overhanging obstacles. ....etc

Abstract
Blind people need to become as independent as
possible in their daily life in order to guarantee a fully social
inclusion. Mobility means the possibility of freely moving,
without support of any accompanying person, at home, in public
and private buildings, and in open spaces, as the streets of the
town. Mobile and wireless technologies, and in particular the
ones used to locate persons or objects, can be used to realize
navigation systems in an intelligent environment. Such systems
open new opportunities to improve the ....etc

Blind since old age have been using walking stick and also walking dogs for their mobility purposes. many different types of electronic travel aid are available: These use either ultrasound or laser beam. One of such devices is the laser cane that is similar to a long cane with built-in laser ranging facilities.Most use ultrasound for functioning.These use the reflectance property of the high frequency ultrasound and are available in different
models like:
1.Sonic torch
a hand held device and operates on the principle of transmittin ....etc
