A creature called the Atlantic razor clam 1 has a secret digging in wet sand should be slow and take a lot of effort, but a razor clam can borrow a centmeter per second and go half a kilometer using only about a double battery worthy 2 of energy, this talent intrigued 3 MIT researchers who thought that the robot of that clam would be practically uses, so they study the models they moves, they found that clam first contract their shells that action causes sight fall inward towards the animal, further shell contraction 4 draws water into the mechs about point the water heat as a fluid quick sand the drag on the borrowing clam is dramatically reduced and it starts to really move the process requires pen point timing 5 contraction of digging based on their findings the researchers built a medal mimic 6, its two hands contract and expand and a rog dig into the sand they believe that energy efficiency of robot clam could anchor autonomous 7 under water vehicle search for mines or lay for water cables scientists discovered their efforts in the journal bioinspiration and bio mimecas rather than climbing up.
