Science is exciting in theory, but it can also be dreadfully dull.Some experiments require hundreds or thousands of repetitions or trials - an excellent opportunity to automate.That''s just what MIT scientists have done, creating a robot that performs a certain experiment, observes the results, and plans a follow-up... and has now done so 100,000 times in the year it''s been operating. The field of fluid dynamics involves a lot of complex and unpredictable forces, and sometimes the best way to understand them is to repeat things over and over until patterns emerge.(Well, it''s a little more complex than that, but this is neither the time nor the place to delve into the general mysteries of fluid dynamics.)One of the observations that needs to be performed is of "vortex-induced vibration," a kind of disturbance that matters a lot to designing ships that travel through water efficiently.
