The Swirling Brain and lots of our other readers have submitted stories about CMU's new robot that can walk on water. The tiny robot is light enough that it doesn't break the surface tension of the water, allowing it to walk on water in the same way as Water Skimmers (aka Jesus Bugs). For more on the Water Strider robot see the stories in Wired News, Forbes, and Slashdot. The CMU robot is similar to the MIT Robostrider robot we reported on last year.
