Design and Construction of Rotating Ultra-Sonic Ranging Device for Environmental Sensing

Abstract

The objectives of this project are designing and constructing a cost-effective system that can sense topography of the environment. Many systems for this purpose have been made worldwidely, but many of them do not cost-effective. For example, MIT has made environmental topography sensing system using laser sensor, which costs more than 5000 USD. Therefore, the alternative system which is more cost-effective is needed.
This system is capable to sense the topography of the environment within a radius of 360o with four ultrasonic sensors that are mounted perpendicularly to each other and work simultaneously. The experiment result concluded that the system can create maps of the environment within a radius of 360o and the speed of the system in making the map depends on the size of the environment. This project is a beginning part of a bigger project. Next step of this project is implementing mapping algorythm in the system so that it can make a full map of the environment.
