Rotating Ultra Sonic Sensor

The objectives of this project are designing and constructing a cost-effective system that able to sense the topography of the environment. Many systems for this purpose have been made, but do not cost-effectively. For example, MIT has made an 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 the radius of 360o with four ultrasonic sensors that are mounted perpendicularly to each other and work simultaneously. The experiment concluded that the system can create maps of the environment within a radius of 360o; 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 of creating a map maker mobile robot.
