Defense forces in Israel plan to use robotic 'snakes' that have the ability to maneuver through cracks in order to send surveillance images and audio back to combat troops. They even have the potential to set explosives into place. The remote controlled robot snakes could also be used to help locate people trapped beneath the rubble of collapsed buildings.http://www.jpost.com/servlet/Satellite?cid=1244371047887&pagename=JPost%2FJPArticle%2FShowFull
NASA and mechanical engineers have also been working on developing robotic snakes.http://www.livescience.com/technology/etc/090610-battlefield-robot-snake.html
