Check out this amazing robot and its capability to adapt to completely different terrains:
Description from the website:
"RHex is a man-portable robot with extraordinary rough terrain mobility. RHex climbs over rock fields, mud, sand, vegetation, railroad tracks, telephone poles and up steep slopes and stairways. RHex has a sealed body, making it fully operational in wet weather, in muddy and swampy conditions, and it can swim on the surface or dive underwater. RHex's remarkable terrain capabilities have been validated in independent testing at US Government Labs.
RHex is controlled remotely from an operator control unit at distances up to 600 meters. A video uplink provides front and rear views from RHex’s onboard cameras. RHex also uplinks navigational data from onboard compass and GPS and from payload sensors. A downlink allows the operator to control mobility and to operate mission payloads."
