Imitation is the sincerest form of flattery, or so the saying goes, and when it comes to the realm of science, why reinvent the wheel when nature already provides us with the relevant examples of how to run things efficiently? Want to fly? Look to the birds. Intend to explore the depths of the oceans without getting crushed by the immense pressure? Check out the ocean life there, and you’ll figure it out. Want to help a boat remain anchored in an assured manner? Ask a clam. At least, this is what MIT researchers have done, resulting in a robotic version of the clam.
