are you sure that your project idea will work?

all the project would be is four or something like that , ultrasonic transducers that emit different wavelengths of sound

You dont need to build a robot in order to produce ultrasonic sounds. Any thing with a speaker can produce ultrasonic sound.

You just have to talk with a bird specialist, record the sounds, get an i-pod and press play.

Do you want a robot, or just a sound maker?
