I can't even get the cnc ribs I had cut a month ago assembled.

I am thinking about adding an ROV. I can mount an ROV garage to the front on the opposite side of the manipulator. The manipulator is close to completion, and I don't have much else to do. I can use the same rotary actuator motor type that I just built for the manipulator for thrusters. I have a real nice aluminum strobe light housing that can be used for the camera. I probably have most of the stuff here to build one. I might need some help with an umbilical cord though.</div><div>Hank</div></div></div><br>______________________________<wbr>_________________<br>
