HTTP:: Robots to Get Fish 039 s 039 Sixth Sense 039 Ability
--------
nn The amazing ability that fish have of essentially touching objects around them without actually coming in physical contact with them comes from their unique sensory system, called the lateral-line. This allows them to sense obstacles in their paths, and to steer clear of predators. Robotics engineers are currently developing new biomimetics technologies that will one day effectively allow future generations of robots to be able to do the same thing. The efforts are spearheaded by scientists at the Technische Universitaet Muenchen, led by Leo van Hermmen, a professor in the Physics Department. It has long been established that humans are only able to experience a limited amount of the information around them. For example, infrared and ultraviolet light, as well as X-rays and gamma-rays remain hidden from us. Some animals have developed specialized organs for identifying an extra “slice of reality,” and the lateral-line in fish and some amphibians is one of these sy!
stems. Van Hermmen, who is the chair of theoretical biophysics at TUM, has been interested in replicating this organ artificially for quite some time now. He gives the example of pike and pickerel, which are able to detect their preys even in murky waters, where little sunlight penetrates in depth an...
