Awesome, and that's why it's in the news:
Germany's automation technology giant Festo has built a group of robot penguins. The robots try to replicate the body shape and fin movements of one of nature's most efficient swimmers and can autonomously navigate using 3D sonar.
Like previous bio-inspired projects, such as robotic manta rays and robotic jelly fish, the robots serve as both a model and testbed for new bio-inspired technologies. Festo's goal is to use bio-inspiration to develop innovative solutions to automation tasks.
One such innovation, a tripod gripper far transcending operating range of conventional grippers, was demonstrated along with the robot penguins.
