A robot sloth will (very slowly) survey endangered species

Most animal-inspired robots are designed to move quickly, but Georgia Tech's latest is just the opposite. Their newly developed SlothBot is built to study animals, plants and the overall environment below them by moving as little as possible. It inches along overhead cables only when necessary, charging itself with solar panels to monitor factors like carbon dioxide levels and weather for as long as possible -- possibly for years. It even crawls toward the sunlight to ensure it stays charged. The 3D-printed shell helps SlothBot blend in (at least in areas where sloths live) while sheltering its equipment from the rain.
