Building a Sibiu Nano, Qgroundcontrol issues

Firstly, yes I should (and will) mail Nido Robotics directly too, I am just hoping that this might be a quick fix so that me and my sons may go exploring tomorrow:

So, after buying a Sibiu Nano Makers Kit, which failed miserably due to a burnt out 5V power supply, I have recieved a new version of the Nido Robotics Motherboard and assembled it into the ROV. Everything boots up, and I get a video feed and control over the camera servo via Qgroundcontrol.

However, the Lumen lights turn on, and are not dimmable or cyclable although correctly configured. (Channel 7, Lights1_brigther/dimmer on buttons that show activation when pressed)

Also, when calibrating the joystick, a “manual control lost” message appears after the first step where no Input is to be given. Then it accepts the first throttle up step, but throttle down is not registrered. This happens repeatedly.

The motors work via the motor test interface as well, so I am a bit confused on how to proceed. Any tip is appriciated, had this thing since mid-july but it havent been close to water yet.

Hi Tor,

Thanks for posting. The guys are Nido are definitely best to ask about this. Some of these issues sound similar to things we have on the BlueROV2 occasionally, but I’m not familiar enough with the Sibiu Nano to help with troubleshooting.

For the Lumens, I’d recommend using the Mavlink Inspector at the top to make sure the output of the servo channels is changing properly.

The rest is a bit uncertain but sounds like it could be spotty communication or some issues with your surface computer.

Let us know if we can help with anything else!

Thanks for your reply! The Guys at Nido Robotics have been absolutely outstanding in helping me out and shipping me parts. They have had some issues with their on board 5v powersupply which in turn have made the Raspeberry Pi misbehave and ultimately stop working.

After troubleshooting my Nano since august, they offered to cover shipping both ways (Norway-Spain-Norway) and to correct the power related issues for free. I’ve had my share of interactions with different customer supports through the years, and this is absolutely top notch. (and judging from how Blue Robotics responds on this forum it seems like the ROV business is quite good at helping their customers)

Oh, and for the lumens, the pins for supplying power and signal had changed from revision 0.3 to 0.4 of their motherboard, so I had connected the signal wire to the pin giving power. The result: lights at 100% constantly. I corrected this, and my lights were dimmable again.

Great to hear @Tor! Thank you for following up.

Recieved my ROV last week, and tested it last night. Not a very scenic dive, but at least I got to test it and it worked very good. Sideways thust and camera tilt was awesome, my Gladius Mini does have a possibility to tilt the entire ROV but that is not as smooth as this.

Now, If only someone could make the BlueROV\Sibiu Nano as portable as the Small Consumer ROVs using WiFi and Tablets…

Anyways, video here:
