robots reacting to sound
July 23, 2008
I've spent most of today daydreaming about the possibility of modifying the 'start here' robot to include some kind of sesiivity to sound.
My idea is to have 2-4 microphones around the robots body. When the robot hears a sound, he compare the levels between the sensors, and turns to face in the direction of the strongest level.
this way you could clap to draw your robot's attention, and make him act a bit more like a living thing.
That's the idea...now the technical side....how do i interface a number of microphones to the PICAXE's analogue inputs?
so far i've found this interfacing circuit ...but it seems to me thatit's far too complex and bulky to have a numbe rof these on the same robot. :/
anybody have any ideas...do you think this could work by just directly hooking up piezo transducers to the analogue inputs? (i think the sensitivity would be far too low then though).
