As it glides sedately beneath the waves, the ray’s languid grace belies a stunning capacity for underwater manoeuvres. With a flap of its wings, Aqua ray can swim upside down, loop the loop, hover or turn on a dime. As agile as a real manta ray, the rubbery, robotic acrobat (pictured right) is the handiwork of Rudolf Bannasch and Leif Kniese of bio-inspiration firm EvoLogics in Berlin, Germany, and could kick-start a new generation of autonomous underwater vehicles. Over the last decade AUVs, which are mostly propeller-driven,
