With inspiration from nature and some help from research at the Massachusetts Institute of Technology, a research team led by Carnegie Mellon engineering assistant professor Metin Sitti has built a tiny robot that can walk on water, much like insects known as water skimmers, water skaters, pond skaters or Jesus bugs.
