I am interested to hear whether anyone has developed a robot that can detect the direction sound is coming from and turn towards it. I figure it should be possible to put a sound sensor on each side and from the respective levels work out which direction to turn to.
Has anyone tried this approach? Successful?
Was thinking about this yesterday. I haven’t attempted it however with the megapi the processor speed would certainly be available to easily process the inputs. Have you attempted to search the internet for sound triangulation using a Raspberry Pi?
I guess I will find out how it goes. I just bought 2 sound sensors for my starter robot, and a servo kit so it can scan a little from side to side when it moves around. Will try to remember to come back and post my findings.
Thanks form the update, I’m definitely intrested in your findings. In the meantime if I have any success I’ll post it also.
Here’s an interesting link about using sound detection as direction locator.ruralhacker.blogspot.pt/p/micloc.html
Seems that the sound sensors were out of stock when I ordered. I have to wait another 2 weeks for the goods to arrive.
I like the idea of collecting sound samples with the robot.
Have you possibly thought about mounting three sensors on a small tripod at fixed locations to gather samples?
An arduino with a master clock and three control circuits could record the time delay between senors.
Just a thought.
I believe I see a tripod, and three Me sound sensors in my near future and possibly even a Me Auriga.
Good luck with your samples, I’ll be looking forward to reading about your results.
