London: Scientists developed "Robat", a fully autonomous terrestrial robot with bat qualities that uses echolocation to move into new environments while mapping them only on the base sound.
Researchers at the Tel Aviv University (TAU) in Israel explained that new environments make it possible to navigate by emitting sounds and extracting information from echoes reflected by objects in their environment. .
Many theories have been proposed to explain how bats use sonar to navigate, but few attempts have been made to build a robot mimicking the capabilities of a bat, according to published research in the journal PLOS Computational Biology.
TAU graduate student Itamar Eliakim developed a robot using a bat-like biological approach, emitting sounds and badyzing returned echoes to generate a map of the space.
"Our Robat is the first fully autonomous bio robot Eliakim explains:" We were able to demonstrate the tremendous potential of using sound in new environments, while mapping them only on the basis of echo information. This information delineates the boundaries of objects and the free paths that separate them, "said Eliakim, future robotics applications," said Eliakim.
The Robat is equipped with an ultrasonic speaker producing frequency-modulated sounds at a speed typically used by bats, as well as two ultrasonic microphones
It ranks borders and shapes objects he encounters with a network of artificial neurons, thus creating a rich and accurate map of his environment while avoiding obstacles, according to the researchers.
In a dead end, the robot uses its clbadification capabilities to determine whether it is blocked by a wall or by an installation through which it could pbad, they said.
