<description>Sand is difficult terrain for robots to navigate. Looking to lizards and cockroaches for clues, Daniel Goldman, a physicist at Georgia Institute of Technology, and his colleagues figured out how to making a robot that wouldn't be slowed by soft ground. The trick? It's all in the step.</description>
