181023-N-PO203-0307 CHARLESTON, S.C. (Oct. 23, 2018) Rear Adm. David Hahn, chief of naval research, operates the Maritime Dexterous Manipulation System (MDMS) from RE2 Robotics while visiting the Office of Naval Research exhibit during the 2018 OCEANS conference and exposition. The MDMS consists of two 5-degree-of-freedom robotic arms with two-finger grippers. The arms are electro-mechanical and are roughly the same size as a human, meaning that when mounted on a smaller underwater vehicle, they can perform human-like tasks. (U.S. Navy photo by John F.
