'Flying fish' robot propels itself by shooting water out of its butt

This illustration shows the combustion in side the robot propelling it out of the water. Engineers often look to nature for inspiration when creating robots. Just look at Astro the robot dog or the antelope-like SpaceBok. A team with the Aerial Robotics Laboratory at the Imperial College London in the UK has developed a floating robot that can shoot a jet of water out of its rear to propel itself through the air. The robot is shaped like a little airplane.
