Robot snake

'Snakes' on the moon? These helpers could soon join our lunar mission.

NASA needs a small army of robots and rovers to help explore the moon’s treacherous terrain. A college competition produced some innovative ideas.

Engineering students from Northeastern University test their snake-like robot, the Crater Observing Bio-inspired Rolling Articulator (COBRA), in the Mojave Desert. Their robot, designed to explore Shackleton crater on the moon's south pole, took the top honor in NASA's Breakthrough, Innovative, and Game-changing (BIG) Idea Challenge.
