Sneaky deep sea robot will take pics of fish without spooking them
Robots typically aren't good choices for studying deep sea animals like jellyfish -- not when their light, noise and movement can scare away those creatures. Researchers at Woods Hole Oceanographic Institution may have a far less intrusive option, though. Their planned Mesobot observer is designed to move as quietly as possible while collecting data about aquatic life. The four-foot-tall robot moves using six large but low-power thrusters that won't cause a stir, and its LED lights can switch to red (which many deep sea species can't see). A two-day running time should also minimize attention-getting trips to the surface.
