Brainstorming for ROV Claw (The claw itself)

• Vertical system

 o Two claws on top and two claws on the bottom


o Come together to encase the ball


o Attached to long arm extending from the hull


• Horizontal system


o Two claws on either side (left and right)


o Come together to encase ball


o Attached to long arm extending from the hull


• Modified horizontal system


o Two claws on either side on the top and bottom of each side


o Vertical pieces extend between the top and bottom parts of the claw


 The top and bottom claw pieces on either side combined with the vertical pieces create a cage when the claw closes


 Completely encases the ball for maximum security


o Attached to a long arm extending from the hull

Brainstorming for ROV Claw

Brainstorming for the Claw (Power)-




• Cylinder system


 1 for opening and closing


 1 for up down pivot


o Pros


 Simple


 Easily kept water tight


 Less likely to fail/easier to manage


o Cons


 Air changes buoyancy balance of the vessel


 air is more unpredictable than electric motor, less accurate


• Electric motor


 gear up or down to make claw control smooth


 gear up or down to make vertical claw pivot smooth


o Pros


 more precise


 no buoyancy complications


 predictable


o Cons


 more complicated, more moving parts


 could tangle wires


 less reliable
