sound Sensor?

 sound Sensor?

I plan to build robot with a 8051.
It will have full artificeal intelligence that will interpret voice commands and 3dee video recognition.

But i have a problem with the plan because i want the robot to turn to the perons when it hears the voice.

The problem is how to make 20cm dimention robot can sense the direction of the voice.

please help make my dream come true > <

My Robot look like this

 Over-ambitious?

I'd have thought that sensing the direction was relatively easy considering all the other stuff you're contemplating - voice commands and 3D video recognition.

Are you, perhaps, being a little over-ambitious here...?

Good luck on the first 2 items. Think 32 MCU.

The sound is easier get 2 mics one on each side. Measure the sound levels. The louder one is closer to that "Ear". Turn that way.

Voice and image recognition and AI with a 8051? Why would anyone try to do this? Oviously wrong tool for the job. That's like trying to build a space shuttle with sticks and glue.
You'd have a much better outlook if you used PC-compatible hardware. This way you'd have access to libraries built for what you are trying to achive.
Build something simple first. Then add new features. Small ones. One at a time. That would be much more realistic.

 RE: sound Sensor?

You are hardly explaining what your problem is. You should give more technical details about what you are doing and what you want to achieve. Otherwise, no one is going to be able to help you out.
