Hello, I recently contacted OpenROV support and after a few emails back and forth, Nicole recommended that I post this up out here to get others involved in the conversation. As I have studied further some of the questions I originally had have been answered fully, or partially. I am reaching that knowledge “tipping point” where I am starting to get a pretty solid big picture.
None of the existing ROV packages out there fit my needs, or they cost as much as my house (so again, not fitting my needs lol). The Trident comes very close, but not available yet, and still not “perfect.”
I want to go with the OpenROV platform though for the most important thing appears to be covered. I need the ability to build my own basestation, or use just about any available platform. So I am thinking to put together my own kit using the 2.8 developers kit. When I priced everything out individually, you basically get a free tether! I will likely go with a neutrally buoyant tether, but the dev kit one will at least get me online.
I have a handful of questions though!
I need a wireless buoy. (At least I think I do!) I will be using an HD camera setup, either the Pro Upgrade and chassis, or the Blue Robotics camera. I won’t go into more details on the BR stuff, but have seen that I am not alone in a hybrid build. Simply put for my needs, their enclosures are more configurable. Otherwise, I am preferring the simpler nature of the OpenROV stuff, and the MUCH better documentation. Anyways, the first question:
Can a 2.4g wireless connection even reliably support the higher HD video data stream? Obviously we are out of the water at this point.
Is there a Tenda wireless adapter that can be used on the topside?
I read the wireless buoy tutorial, but it seems that there has to be a cleaner way to build it… I can’t fully wrap my head around this. Now if I could power the topside buoy through the tether from the ROV main battery, using a setup otherwise like the tutorial would make a little more sense.
I need a different main chassis configuration. I tempt fate here as I am sure it will take me some effort to get my design balanced. The sides will have a tie fighter like look, like the Shark Marine’s Stealth 2 visible here:
My main concern is that ideally I (think I) want 2 vertical thrusters and the 2 horizontal thrusters. It appears the controller board has outputs for 6 various servo or esc based devices. I am just unsure how one goes about applying those. Is the interface similar to say Open Pilot (well actually now Libre Pilot), or Betaflight for air based UAV’s?
How does the controller function, would a fourth ESC be added in parallel to the vertical thruster esc?
Can I order additional ESCs from you guys? Or better yet, can I order the controller board without esc’s and use my own?
Would the software image need to be changed to function with a 4th thruster? Or again, is this handled via a interface like Open Pilot…. ??? Also how does it handle more thrusters, say 6 like some other platforms use? Documentation claims control up to six thrusters, but a glance at the pictures only showed obvious spots for the 3…
Can I order the scaling laser diodes separately? Or get a digikey part number? I may not be using the OpenROV camera module as I really want the ability to upgrade the camera, and possibly record video onboard.
Final question, for now!
- Can I use “any” USB joystick or gamepad controller? If so, how and where do I program the functions?
I have a Saitek Cyborg 3 that i purchased as soon as I saw it the other day, just for this project! Hopefully it can be utilized…
My apologies as I am SURE lots of these questions are covered in various places in the different guides. I have seen a few of my questions kinda touched on as I research them (and in fact did find and answer a few I deleted).
I will try to wait patiently for answers lol! I am waiting on some of these to decide on final parts to order. It would be cheaper to buy a full kit, but I want the flexibility of a slightly different configuration, as mentioned first thing above.
I do have an extensive background in arial drones and electronics. But this is new territory and as such the information out there (in general) is pretty scarce. Thank you guys in advance for your help!
