Bats' Echolocation Recorded and Recreated

Bats can see in the darkness by using the sounds of the echoes of their surroundings. Engineers are trying to replicate this skill. A team of British researchers has worked with six adult Egyptian fruit bats from Tropical World in hope to record and recreate their calls. These calls are pairs of clicks from the bats' tongues that they use to fill whats around them with acoustic energy; the echoes that return let the bats form an image of their environment. They worked with the bats to record their double click echolocation call, and its returning echoes, using a little wireless microphone sensor on the bat while in flight.

They planned to use this for robotic vehicles.This is a very interesting topic and its cool how they found a way to make the robotic vehicles do this. I think that all the time doing research was worth it. Applying this skill for us is very cool also.
