Alternatice solution 1

Alternative solution One
For my first alternative solution I chose to design an arm that has a basic horizontal closing action. This arm has is run by a simple motor and screw motion. The screw, which is colored purple in the isometric drawing is turned by the motor( color), which in turn causes the gears( brown) to be turned, which opens or closes the claw depending on if the motors turns the screw in reverse or not. The moving parts of the claw will be housed in either PVC or some other material than can be easily accessed if a problem needs to be resolved. The motor will be attached to the rear of the actual arm, and will sit inside the actual body of the ROV. This design will allow the ROV to grab objects ranging in size from very small to medium size objects, depending on the width of the objects.
