Introduction: 2D Ultrasonic Mapping

Picture of 2D Ultrasonic Mapping

In this instructable we will shows you how to use a sonar sensor to create a 2D maps of surrounding objects. This project is part of the landmine detecting quadcopter project by SRJC Computer Science Club. This part of the project will allow the quadcopter to detect objects in it's surrounding.

Cool sonar system

Thank you. It is work in progress we are going to replace the ultrasonic range finder with Liar-lite v2 so we can get a better resolution.
