-Heavy frame eight thrusters
-IP 4k varifocal camera system with focus and zoom control on the joystcik
-New configuration of thrusters, leaving all the lower space of the ROV free, with space for three 4" watertight enclosure.
-Fast on-off ignition system, with 80A relay system, in 3" watertight enclosure with space for 18000mah batteries from bluerobotics
-9000 mah batteries (developed for our usual use of short dives)
-More paid load thanks to buaynacy foam of polyurethane (density 250kgr / m3), CNC machined and coated with epoxy resin and two-component polyurethane paint.
-Stern protection to avoid snagging in ROV recovery.
Great looking ROV, love the foam and neat tether arrangement.
Did you strip down a 4k security IP camera or purchase it in stripped down form - looks exactly what I’ve been planning to do - do you mind telling me what camera you used?
Thanks for the comment!! I use a 4k IP module, you can find different models on aliexpress, 12 mp, 8 mp, 5 mp and different motorized lenses. My model is 8 mp but it depends on the use you are going to give it and your needs, so I recommend that you choose the one you like best on aliexpress. All have an economic price and give good results.
I’ve already been able to do some tests with the ROV, and it has very good underwater control with the propellers on the same axis as the camera. The propeller movement does not affect the image and I think the image quality is quite good.
Attached video of the first dive, it is important to download the video to see it in full quality. The image is a little greenish because there was a strong phytoplankton bloom. But you can appreciate the quality equally.
Hello it´s a great project, but I have a question. Did not give you problems the bandwidth due to the resolution? Or in any case how did you handle it?
Indeed I use a Fathom X dedicated to the IP camera. But I only use one twisted pair, that is, two fathom X on the ROV and one on the surface. In other words, the communication of the camera and the ROV is carried out on a twisted pair.
On the other hand, I use another twisted pair to control the zoom and focus with the ROV’s own joystick.
