Fish-like Sensors for Underwater Robots 57

Roland Piquepaille writes "Today, both submarine and surface ships use sonar for navigation. But sonar and other vision systems face various limitations. So why not imitating fish? For millions of years, fish have relied on 'a row of specialized sensory organs along the sides of their bodies, called the lateral line' to avoid predators or to find preys. So engineers at the University of Illinois at Urbana-Champaign (UIUC) have decided to build an artificial lateral line for submarines and autonomous underwater vehicles (AUVs). The first tests have been successful, and we can now envision a day where AUVs could detect and track moving underwater targets or avoid collisions with moving or stationary objects."

    I always laugh at the idiots who claim that Iran or NK (or even Iraq) is a threat to us. They are small countries that we can put in to 5 nukes and destroy the total country. In contrast, these countries do not have the economic might to build enough nukes to threaten all of their enemy (nk => sk, and Iran => Isreal), let alone USA. Finally, our current anti missile systems are capable of taking our any thing that is inbound. Shortly, we will have lasers with better capabilities. Of course, I have to admit that I do not want to be at the target point counting on the American system to work flawlessly.

    China is in the process of trying to destroy America. It is not the fact that jobs are moving there. It is the fact that they have their money fixed to ours which prevents any real competition. But that is by design. It is obvious that they are attempting to remove our manufacturing base, and then bankrupt us. Once the base is gone, so is the ability to build a strong military, space, medical, or even educational systems. Sadly, by the time that the average voter figures this out, we will already be federally bankrupt (if we are not already there), AND will be in so much debt that we can not get out.
