A robot that walks on water

July 27, 2007 The NanoRobotics team at Carnegie Mellon University (CMU) are working on a robot that walks on water, mimicking the Basilisk, or "Jesus Lizard" that's famous for its ability to dash across a water surface on its hind legs. Researchers see amphibious potential in the water-walking robot, as well as a possible efficiency boost in comparison to a boat, because a vehicle that runs across the surface of water experiences very little viscous drag. Computer simulations have been encouraging, demonstrating a few possible efficiency gains in the design and motion over the evolutionary model provided by the Basilisk, particularly with the option of using two or more sets of running legs. Several leg designs have been tested (see one in action in this video (MP4)) but the researchers are still working on an operating prototype.
