The big brother of the RCV -225, the RCV-150 was developed as a highly maneuverable, light-work capable ROV. This vehicle, in addition to being a flying eyeball, has a four function manipulator capability including both a rotary saw, pinching blade and grabber jaw. The RCV-150 has recently been fitted with a second four function arm extending the work capabilities to much more extensive and complex tasks.
Figure 9 shows the manipulator assembly. The manipulator is a five-function work arm normally stowed inside the lower framework in the vehicle. A rotary actuator at a "shoulder" joint allows for stow and unstow motion of the arm. An actuator at the "wrist" allows grabber jaws to pivot in a 245-degree arc. The jaws are opened and closed by a linear piston actuator. A pinching blade, capable of cutting 3/4 inch polypropylene line, is actuated simultaneously with the jaws.
