Gripping Tale
Photograph by Bob Bllard

Hercules is right-handed. The ROV's left arm performs only basic holding and stabilization chores and is much less dexterous than its counterpart. Hercules'  "smart" arm uses a maneuverable claw called a manipulator, which sends operators tactile information about each object it finds. This allows them to control the pressure of its grasp and the speed and movement of the manipulator. Here the ROV loads an amphora from a Black Sea wreck into the mesh elevator so it can be brought back to the surface.
