Hi guys!
have to build a hovercraft as part of a third year Eletircal engineering project. It must hover through a maze without touching the sides of the walls. I've decided to use ultrasonic sensors to measure distances as opposed to infra red (reason being - ambient lighting will pose big problems !). Just a quick question - will i have big problems using ultrasonic in terms of the sound waves hitting the floor and bouncing back and thus not getting the desired result. In theory (or in my mind) the waves must just hit the wall and bounce back - then i can measure a distance using speed time distance formula. However will waves hit the floor and will these reverberations cause big problems or will they be negligible. If anyway can give me some sort of answer - it will greatly be appreciated.
THANKS
