ArduPilot 2.2 software released -- now with built-in stabilization! [Archive] - Page 4

as far as how many ardu's are sold and how many are in the air.... I would imagine that there is not 1100 working ardupilots out there.... it would be an interesting survey.

ArduPilot is an open source development platform for RC-connected robotics of all sort, from planes to cars and boats to just benchtop experimentation. As its core, it's just an Arduino board and like most Arduino development boards it's used as much for learning as it is for in-field operations.

I'd guess that about 10% of the ArduPilots have flown. But with the latest software (2.3), it's stable and pretty much ready to fly autonomously out of the box on the recommended platform (EasyStar), so I expect that number will rise.

Judging just from the tech support, it's moved from basic code loading and assembly questions to airframe tuning questions, which is a good sign!

The manual is really pretty good. About the only thing I could see adding to it is some details about what the airframe settings do, and maybe some expected ranges for the values. There are some comments in the code of course, but not enough to really make it clear. That being said, I haven't downloaded a copy of the manual in a couple weeks, so maybe that's changed too.

As for the percent of successful installations, it would be an interesting poll, but to be fair, you'd have to take into account the people who bought more than one, and also the people who've never really put any effort into getting it working. I imagine you'd also have to factor in the people who really shouldn't have tried to make such a thing work. It really wouldn't be easy to make a fair poll.

I've had my share of issues, but I finally have it working at least in the RTL mode. The frustrating problem I had turned out to be TWO bad FMA XY sensors. Both had a bad X axis, which made me go down the wrong path trying to troubleshoot it.

good points for sure.

that would be very frusterating with the fma sensors.

My biggest frusteration has been getting the darn code to load. the adru environment just will not run happily on my machines.

For sure it's all about fun and development. that is why I have an atto for work and the ardu for tinkering.

all I want from the ardu is a RTL scenario and maybe a wp or two. Nothing crazy.

We're now upgrading the default ArduPilot to the excellent uBlox 5 with the helical antenna (keeps sat lock from any angle). It's now available (http://store.diydrones.com/ProductDetails.asp?ProductCode=SPK-GPS-GS407) in the DIY Drones store. It comes with an adapter that allows it to be used in 3.3v or 5v systems and has a battery backup to retain settings. It also allows the uBlox to use the the standard EM406 cable (http://www.sparkfun.com/commerce/product_info.php?products_id=9123)/connector, solving one of the biggest problems with uBlox modules to date (funky connectors or none at all).

It's $109, which is the same price as the module and adapter separately, but this one comes pre-programmed for ArduPilot or Paparazzi (basically the standard settings you'd want for a UAV, optimizing it for airborne use), saving you a very fiddly setup process.

I'm just getting into the information finding of autopiloting. The Ardupilot sounds very interesting, but I've got a lot to learn. I did see in another post something about a new version coming out that wouldn't need the XYZ sensors (I think). Perhaps it's worth the wait for that to be developed and released before jumping in.?

Greetings,

Is anyone here successfully flying waypoints? I've got the latest versions of the hardware and software, including the HappyK config tool. RTL works pretty well, but that's all it does, even when I select the waypoint position. I've verified that the green LED is coming on when I select the center position of the switch, so it should be in waypoint mode. It just never makes any attempt to fly to the waypoints I've saved.

The most likely problem is user error, but I'd love to know what I'm doing wrong. At my house, I program two waypoints that are about a quarter of a mile apart. The "home" position is shown as my house of course, but when I do the field setup, that should change to the field location. Clearly it does too, because RTL comes right back to where I started, and circles overhead (while I swat mosquitoes, horseflies, coyotes, etc). Shouldn't this work?

Barring any better suggestion, I've set it up with a manual "home" location in the center of the field, which is actually better anyway. The two waypoints are there as well, and the next time I fly, I won't do the field setup, to be sure it uses the manual home position.

Thanks,
Rusty

Rusty, HappyK's utility is still not working right, which is why we haven't made it an official release. Stick with the official config utility for now. Lots of people are successfully flying waypoints with that, and as soon as we can work with HappyK to debug his code, we'll switch to that.

Hi all, I seem to have everything ready for another test on wed night but I can't seem to get my home position to read off the board... I am using the latest config tool from the code page.

When I hit red it says that it reads sucessfully and when I write waypoints to it I can read them back... but I cant get home to come up anywhere...

I set the jumper, set switch to manual, power the board the blue light flashes, I unplug the bind plug, it gets a lock, moved the control surfaces, I reset the board, unplug the gps (so that I can read and write to the board) then hit read... it says it reads it fine but does not bring up my home position...

any thoughts?

oh yeah and that is what was not good the last time I commented on this... because my home position won't come up I get home somewhere off in china, even if I move it then it's still not where I am flying... it would be nice to turn it off..

As mentioned over at DIY Drones, HappyK and Jordi are looking into this. I'm on the road and can't check right now, but have you downloaded the latest ArduPilot code (2.31?). It was updated last week to work with HappyK's latest config utility, and maybe that solved the prob? If not, we'll get it fixed pronto.

yes sorry I finaly found the post over there and posted the question in both spots. I see I am not the only one. I have the latest code and latest config tool.

Tomorrow night I will find out if home is actually set and just not coming up or if it is not being written to the memory at all.

Oct 13, 2009, 04:29 PM

thre is always some comparison and discussion between atto and ardu the comparison bewtween atto and adru is a bit like apples to oranges.

I have both, atto fly's my plane great... adru is still a work in progress.

Ardu costs almost 400$ in parts and in continuously changing. I had to buy two sets of thermopiles and now I see the sheild is obsolete... why? I don't know. Following adru and it's latest bugs / fixes is tough to do on DIY drones site. That has been stated by many people, not just me.

so yes Atto is twice the price. Do you get twice the product? IMHO... you almost do. You have onboard data logging and some really great triggering features all built in.

I feel very confident in atto. I don't feel confident in ardu. That is worth something to me.

I like having ardu and hope to get it up and running one day, it's a neat project but it's just that... a project.

When you get the atto you get customer service. Is that worth something? to me it is. You don't get "well it's working for us here" you get an email back and or a phone call if required.

It all adds up.

I am in the market for an IMU autopilot and will be seriously considering the atto. Would I spend almost twice the price again on an atto knowing what i know about ardu... the answer is yes.

HappyKillmore

Oct 13, 2009, 05:20 PM

I have no doubt Atto is a great product. I'm not bashing it. I didn't mean to make this a contest.... I was just considering buying one (on a whim) to see what it would take to make the config tool work with it.... and to have something else to play with.

$800 is way out of my toy budget right now.

I didn't mean to put down Atto at all.... It's really a bash on my personal finances :eek:

How do you get to $400?

ArduPilot is:
--The main board: $24.95
--uBlox GPS and adapter: $89
--Shield expansion board: $48
--XYZ sensors: $114

That's a total of $275, ready to fly.

As for your complaint that the components keep "changing", that's what most people call "developing". Would you rather we stop innovating and improving the product?

If you add in his second set of sensors you get 399 so I would bet that’s what he was talking about.

Hey Chris, How’s it coming on the Atto integration to the Ardu GCS?

Oct 13, 2009, 05:56 PM

hey i am not complainng at all.. as a matter of fact if you read what I wrote I even state here and many other places that i like my adru and the software.

you can include my second set of sensors sure but if you were to add in a current sensor, data logging hardware and realted wiring that all comes with ardu you are pushing 400 and lets be honest here there is nothing ready to fly about adrupilot.

So to set the record straight again.. I like my adru, I love my atto, I like different things about both but comparing one to the other is not relative.

also I am glad you develope but the more things change the more you have to buy to keep up, so that equals expense, like the sensors, gps etc.

I have never said anything negative about either product but I also call a spade a spade and for the purpose of discussion I am being honest as someone not affliated with either product.

I did not intend to step on anyones toes here but if we are going to compare price you have to take into more than the cost of the boards like support, functionality etc.

I would never bash all the hard work done by others to get the rest of us (whom could never do it on their own) as far as you all have and I thank you!

I just meant more that by the time someone gets ardu in the air wih same capabilites of atto you are looking at a closer price point than some people realise.

Again, well done on the ardu sofware, keep at it.

Not sure why he bought a second set of sensors. Needless to say, you only need one!

We've got Atto support in the development roadmap for our next GCS designed for ArduPilot Mega. But that won't be out until the end of the year, and Atto support may not be in the first rev.

I bought two because the fma sensors are not supported anymore.

I bought xy sensors from fma, then the z sensor was discontinued, but in the mean time I was told that the z sensors from the pap system would work so I bought a z from them... I found out that you can't have a different z from the xy's. So now I bought the xyz from DIY.

Bad timing I know but I am not taking that into account here. I am saying that if you add a current sensor, data logging, related wiring etc. you would be pushing 400$ so about half the price of atto. So you pay another 400$ for software functionality, support and the fact that it works and I don't have to try getting the code to load on 3 computers before it works. I can adjust the set file with any computer or laptop at any time...

like I say... both cool.. but very different....

zlite

Oct 13, 2009, 06:25 PM

I bought two because the fma sensors are not supported anymore.

The FMA sensors are still supported! (they're what I use). It's just that FMA stopped making the Z sensor and you need to have a matched set of XY and Z. For people who already have a FMA XY and Z, all is good. For people who just have a FMA XY, the cheapest solution is to buy another XY from FMA and use it as a Z. Works fine.

So, to be clear, you can use:

--DIY Drones XYZ sensors
--Paparazzi XYZ sensors (although you'll need to splice the connector)
--Attopilot XYZ sensors (ditto)
--Two FMA XY sensors

Any one of those work great.

The UAV DevBoard is only $150, and it needs a config tool also :D

Rusty

Bill's UAVDevBoard has really matured over the past few months and is now a serious competitor in the IMU-based AP space. The only issue that makes it tough for some people is that it requires a PIC programmer to do anything, including changing waypoints, and that the only interface with the board is a C programming IDE (there's no way that we know of to use a easy desktop config tool to shield the user from this, the way we do with ArduPilot).

But if you're okay dealing with an IDE (and I expect lots of people here are), this board is worth serious consideration. As you know we've worked closely with Bill on this and ArduPilot Mega's IMU is based on his code, so in the next iteration or two of the DevBoard and ArduPilot we may be close to merging the two projects.

No, you don't need more than a PIC programmer. What were you referring to?

And there are people posting daily on their experiences with the UAVDevBoard over at DIY Drones. Bill's very good at responding, so you can track it all by following him (http://diydrones.com/profile/WilliamPremerlani?xg_source=activity). For whatever reason, these RC Groups threads aren't very popular with our community, so almost all the discussion is over there.

BTW, more than 200 UAV DevBoards have been sold (and more than 1,400 ArduPilots), so their user communities are now pretty vibrant. And since they're both open source, the development is now being driven by community members, not just the original designers. Very cool to watch.

I think if you want an IMU-based board, the current UAVDevBoard (it's about to get a better name, btw) is the best deal on the market. I've got no stake in it, so that's my honest opinion. You'll need to get a PIC Programmer ($34 (http://www.microchipdirect.com/productsearch.aspx?Keywords=PG164120)) and an EM406 GPS ($60 (http://www.sparkfun.com/commerce/product_info.php?products_id=465)), but that's it--about $250 all told. No soldering required. Pretty much load the code and go...

So what level of support does Ardu have for the Ardupilot Sensor Board - Six Degrees of Freedom? It appears to attach to the main Ardu board (analog inputs) with its two daughter cards, but needs 3.3 regulated - from the shield board?
Does it replace the heat sensors? Can it do dead reckoning?

All the support and news on this is over at DIY Drones, but the simple answer is that these are different products and not designed to work together initially: one is an autopilot designed for thermopiles and the other is a stand-alone AHRS. That said, we will be releasing a "thermopile replacement" version of the IMU that will be a plug-and-place replacement for the current XYZ sensors (that will probably be out early next year). The next version of ArduPilot (called ArduPilot Mega and also out early next year) will have the IMU built in.

It cannot do dead reckoning because it does not have a magnetometer. It requires a GPS.

Oct 20, 2009, 12:22 AM

So I can use the upcoming sensor in the current Ardu, or wait for the mega.

Now that is very cool.

Maybe I can add a fluxgate compass, or would you need three axes?

Also - "The Wii nunchuck and Motion plus for the Nitendo Wii game contain a 3axis accelerometer and 3 axis gyro. AND it is i2c to communicate to them 4 wires power (3.3v), ground, i2c scl, and i2c sda. The output is 14 bit ADC 'ed i2c bus" $32

Hi.
I have been following this thread. I didn't see any info on the behavior of the ardupilot in mountainous area. In my area ther is not a defined horizon because of the mountains around. So will this auto pilot with the ir sensors work or should i wait for the imu version?

We've never had trouble around hills and other thermopile-based autopilots, such as Paparazzi and AttoPilot have also reported good success in anything other than deep mountain gully's.

i have some trouble with my first setup from ardu.plane going down all the time with nose if i switshed into WP or RTL. :mad:

servo dierection are good on the ground....

question to z-sensor : is it regardless wich IR-diode from z-sensor looking in the sky ? :confused:

thanks.

Funza, have you tried it in fly-by-wire mode (GPS disconnected)? If it works that way, then you know the physical connections are good and we can focus on getting your configuration settings right.

The Z sensor should be placed as it is in the manual, but to be honest I think the ground configuration process should be able to handle it regardless.

hello chris,

yes I'm flying in the modus fly-by-wire.roll ist stabilized.and i can fly right and left.if i fly straight on, plane flying good and hold dierection and alt .

BUT: if i turned manually right or left, the nose goes down !! i can not give manually impule for elevator per RC !
in manually mode all ok.

my Z-sensor is looking up & down.But the sensor has 2 diodes... does not matter who sees the top?

I do not understand that :( :mad: in manually is elevator ok and in stabi-mode ist elevator dead.and i can not control it .... :confused:

Olli, if elevator is working in manual mode but not in fly-by-wire, the only things I can think of are:

1) You've got one of the fly-by-wire configuration settings set to 0 by mistake

2) The RC-in calibrations (such as line 3-3) have been changed.

3) Something else has been changed in your PID settings.

4) A very strange RC system with a weird voltage range.

The best thing would be if you just return to the default easystar.h config file in the .zip distribution file. If it's still not working, then we can focus on hardware setup issues.

hmm ok i will use the standard easystarh.h file....

my RC ist a MX-22 with the LRS_long range 433 MHZ from thomas scherrer...

you have heard of problems with this rc?

my header-file is here...
