The primary objective of this paper is to permit blind persons to explore autonomously in the outside environment. Ordinary route navigational systems in the outdoor environment are expensive and its manufacturing is time consuming. Blind people are at extensive drawback as they regularly do not have the data which is required, while passing obstacles and dangers. They generally have little information about data such as landmarks, heading and self velocity information that is crucial for them to explore through new environment. It is our conviction that advances in innovations could help and encourage these blind persons in their regular operations. This work goes for giving the route to blind persons, by designing a cost - effective and more flexible navigation system. Here we are developing a navigation system that makes use of sounds in order to provide navigation instruction to the user the conversion of speech into a text is done by a pocket sphinx and Google API, whereas the text to speech conversion is done by Espeak. Route navigation is taken care by a Raspberry pi. Ultrasonic sensor is being used for detecting obstacles and a water level sensor is used for detecting water. We can also get weather update by using this system. MEMS sensor is used to intimate the user’s friend in case of emergency. The whole system is mounted to a pack that is fitted to an ordinary white cane. It is light and convenient and it doesn’t obstruct any of the client’s detects while it is being utilized.
