ArduPilot Partner CUAV new hardware


(Matt) #41

Chris, you’re providing absolutely nothing in response but repetitive fluff. So I’m not going to waste my time discussing it any further with you. Either you do not know the information I’ve asked, or are unwilling to provide it, or a little of both. It’s not getting either of us anywhere.

@tridge, Thank you for the follow up with actual information on the product and your experience with it. I think the features they’ve added are good ones. Regarding the faster processor and additional memory, what benefit is that bringing to the users today? From what I recall (and I’m obviously not an expert on this), the Cube was not running our of memory or processing power with Chibios. It had a rather dramatic surplus. So while having more memory and a faster processor is a feather in it’s cap, is it actually accomplishing anything?

The reason I keep asking about the technological advancement and the actual improvements the community will experience is to determine if anything about this actually justifies copying and undercutting the design of the Cube and all the work that went into it. If CUAV has produced a product that will significantly advance the community, and it happens to also be designed to detract from and undercut the Cube, then so be it. That’s actual competition. If the changes are all essentially superficial and have no real meaningful impact, then it’s nothing more than a typical sleazy undercutting with some minor differences so they can pretend it isn’t.

This right here is a nice feature! My favorite feature of the Skyviper you built is the APWeb component. While I’m sure not a lot of “professionals” would use a web interface for working with their build, I thought the ability to load firmwares, pull dataflash logs, calibrate, and all sorts of other things through that Web interface were a HUGE benefit. Is APWeb be a feature that could be added to this board?

Thanks for shedding light on the actual technical improvements of the board.

I don’t care to to get involved in the 3DR clone war that continues from the past.

As I said, and this should’ve been fairly clear:


(tridge) #44

Right now the additional CPU and memory won’t make a big difference. That will change however.
For example, the on-board Lua scripting that @WickedShell is working on will really benefit from extra memory and CPU.
The other aspect of this is that software tend to expand to take advantage of available hardware. So as STM32F7 processors become more common ArduPilot will start gaining features to take advantage of them. I wouldn’t be surprised if Paul and Leonard start taking advantage of the hardware double precision floating point that it has.
The F427 in the Hex black cube is still a great MCU for ArduPilot right now though, and we will keep boards based around it working for a very long time to come. What I expect will happen is we’ll start getting new options to take advantage of the new features. Whether that matters for you depends on what you are doing.
Cheers, Tridge

not the full APWeb as it is an ESP8266 and doesn’t have enough memory for the full APWeb code. It can still be very useful though.
The firmware that comes on the WiFi adapter is quite basic. We should be able to update it with mavesp8266. That will allow it to run at high baudrates, and be useful for log download. It may also be able to be setup for firmware upload.
Cheers, Tridge

maybe has also somthing to see that the web page of CUAV is in chinese. I bought almost a year ago the CUAV pixhack V3, but at the beginning I was totally lost because I couldn’t find any documentation about the pins, and how to connect it to the different devices of my cuad. Thanks to TBS, that post complete schema of the FC I could connect it.
I really thing that you produce very good products, but, If you like to address them to the international community, you have to do an effort to provide enough english documentation.
Thank you very much for your attention and comprehension


(Hugues) #47

I have reviewed the CUAV V3 board which showed it to be a quite good product.

I also much prefer this form factor versus the Pixhawk2.1 form factor.


(Jiro Hattori) #48

There is backlash when CUAV popup as partners of ArdPilot with less respect for Cube. I understand developers have very hard time after 3DR failure. They really need solid echo system. And we are also in that echo system. Then, I would like to know the partnership program. It should be identify how much contribute by individual partners to development work of AruPilot. Something like partners grade identification will be enough to know when we purchase hardwares, such as Platinum, Gold, Silver, etc.


(Tim Jones) #49

this brand just goes on my list of no buy products along side MRO and DJI


(Luís Vale Gonçalves) #50

All partners are of equal status, regardless of the contribution they do to support the ArduPilot project, as you can see here http://ardupilot.org/about/Partners#howto

http://ardupilot.org/copter/docs/common-partners.html#what-do-i-get-for-becoming-an-ardupilot-partner

The order of the partners logo on that page shows the order they’ve became partners, newer partners are added to the bottom of the list.


(Luís Vale Gonçalves) #51

Besides the corporate partners, the ArduPilot project also relies on individual contributions, from the community, as you can see here

http://ardupilot.org/copter/docs/common-donation.html#common-donation

This is a project that is counting on the entire community, either individual users and corporations, to push forward the state of the art on autonomous control of vehicles.

Everybody is welcome to help as best as possible.


(Jiro Hattori) #52

It becomes much clear on partnership program. So that partnership program is one of the support system but not enough to support ArduPilot echo system. Because to ask those things is that I just have curiosity on those echo system might be fair enough and make everybody happy. Thanks.


(Chris Olson) #53

Not my blog (sorry Luis!) but I didn’t know if I was the first to fly a Pixhack V5 in a heli or Luis beat me to it.

Stuck to the side of the frame with Velcro. I really like the peripheral rail on the end of the carrier. Makes for neater wire routing. Somebody figured out that the GPS cables are usually too short and a few cm extra cable means not having to hack a cable extension. And the cable is round so it’s easier to route.

I didn’t install the buzzer/button as I don’t care for music tones emanating from my helicopters. Neither did I use the Power Module as this unit will be going in a piston helicopter next. We only monitor battery voltage with the RC telemetry in those, as the generator keeps the battery charged. So I made up a power cable to run the board on a 2S LiPo with a 5V regulator. It will have redundant power supplies in the piston machine, but for this test we just hooked up one.

100_0179

It works:

The vibes are mostly below 5, but a few spikes up to 10 in the rolls. IMU aliasing is, like, not there. Non-existent. This thing looks to be every bit as good as the Pixhack v3 for the internal IMU damping design. For some reason, ChibiOS does not appear to be putting a date stamp on the BIN logs. That is normal when there is no GPS, but it had 20 satellites on this test and still no date stamp on the log except for Dec 31, 1979. Unix Epoch is 1969, so that must be because the SD card has a FAT file system.


(Rob_Lefebvre) #54

And that, is the problem. Partners who support the project more, have zero public-facing thanks or recognition.

When’s the last time CUAV helped the Ardupilot developers solve a problem? When is the last time they helped their customers get something flying?

$1000 is chump change to get your name on a list next to ProfiCNC.


(Rob_Lefebvre) #55

Yes, typically cloners can’t even be bothered to produce documentation of their product. They just toss the hardware up on BangGood and then expect hobbyists on RCG to support it for them. Or copy the hardware designs originator’s documentation. The worst is when Ardupilot developers are required to spend their valuable time supporting the hardware, making software fixes for bugs in the hardware, etc.


(Luís Vale Gonçalves) #56

Thanks for your always constructive feedback @Rob_Lefebvre

As you remember, the partnership rules were decided by the team, when I believe you were still an active member.

If now, you believe they need to change, you know how to submit your proposal to a team vote.


(Olivier Brousse) #57

Rob, required? Developers as individuals choose what they like to work on and support, based on their own preferences and judgments, just like members of the community at large choose where, how or if they like to help, and/or what they want to buy. No one is coercing anyone, or could.

Seems there’s sometimes been a lack of awareness of this fact in this conversation.


(Luís Vale Gonçalves) #58

@ChrisOlson Almost… you made me fly at night from my balcony to get the first v5 on the air with a Quad, including manual precision take-off and landing :blush:

But TradHelis win after all, because this test quad has a “repurposed” landing gear from a 450 :smile:


(Rob_Lefebvre) #59

I gave up trying to influence the direction of decisions long before I officially resigned.

Rob, required? Developers as individuals choose

Ok, you got me, wrong word.
