Thanks so much for the good words. Yes more RPi/Pixhawk stuff coming soon. Take care.

Hi sir. I have done the dronekit configuration. However, I can only read from Pixhawk, I couldn't send commands from RPI to pixhawk. Any idea why?

Good luck on your project and thanks for the good words. I appreciate it.

I'm not sure if you're into programming at all, but if you are I'd love for you to join our gitter chat sometime. Maybe we can collaborate on some projects together. gitter.im/dbaldwin/DronePan Take care.

Keith, Emlid looks like some serious computing power! I'm familiar with Edison but wasn't familiar with Emlid until you mentioned it. I'll post an update soon and hopefully we can all learn from each other on this topic. Thanks for the feedback and I hope all is well.

Thank you for watching.

Hii which document is this?

@@ishikakajaria8754 which document means????

@@anujregmi4582 the linux installation one but I found it thanks. I keep getting Link one down after I test the mavproxy. Can u help me why this is happening?

@@ishikakajaria8754 Well Currently i am not working in that but i cannot say you exactly what is going wrong i need more information, I can try to see if possible send me a video. But there is another guy also who has made a recent video about raspberry pi connection with Pixhawk. This is his video link: kzfaq.info/get/bejne/oahpjNx4l7yRnnU.html

Thank so much for the feedback.

No problem. I've really enjoyed the flexibility of having a companion computer that communicates with the main flight controller. It really opens the doors for some interesting drone applications.

Thanks for following. Appreciate the feedback.

I had trouble with this myself, but ended up getting it working. I would be very interested if someone has a better suggestion: -I bought a set of "Dupont" wires -My pixhawk came with a telem to telem 6 pin wire I cut the telem cable in half, and spliced each of the wires to a dupont wire of the corresponding color (leaving the 4th, and 5th pins unconnected) according to these instructions: www.researchgate.net/publication/323683430_Communicating_with_Raspberry_Pi_via_MAVLink

Glad it helped and good luck with your Beaglebone project. Keep us posted on your progress!

Thanks for the good words. I'll try to post more often. Appreciate your feedback.

It should be.

You and me both :) Thanks for following along and I hope all is well.

The pi3 continues to reboot , and I can't connect through ssh . So I plug in hdmi , and see the pi trying to reboot . So I solder small power outlet wires from main board , and install ubec and plug into pi . Now I can ssh to pi no more trying to reboot everything works good . Don't use telemetry port 2 to power pi .

I have a similar experience where the pi kept trying to reboot when it was powered from the telemetry 2 port. I ended up using a small powerbank to power the pi via its own usb port and strapped it to my drone.

Thanks for the feedback. Good luck when you get around to it. I think you'll find the possibilities are limitless.

Sounds like an awesome rover!!! I'm by no means an expert when it comes to object recognition, but will hack together an example. Thanks for following along.

My pleasure. I've really enjoyed working with Pi and Pixhawk, of course. Thanks for following.

I've been wanting to check that out. Thanks for sharing your experience.

sir i have done everything but unable to

Appreciate it. I will be posting an update soon.

No big plan other than experimenting with opencv and some other external sensors to give input to Pixhawk. I'd love to get OpenCV object recognition for avoidance and tracking. I'm not an expert in this area, but want to experiment with that combined with DroneKit. Hope that gives you some insight. If you have any suggestions I'd love to hear them. Thanks.

I hear you. There is always never enough time ;) Thanks for the feedback.

Thanks, Phil. Good luck with your projects.

Dennis Baldwin My main interest is in using thermal imaging on a drone. I have a Tarot 680 with Pixhawk and Four Duo-R almost ready to fly, so interested in how I may be able to add some AI functions.

No problem. Glad it helped.

I wish it was Christmas here in TX so it wasn't so hot! Glad you are into all these technologies. I absolutely love them. Have a great week yourself.

So glad to hear that. Good work Ashley!

This is such a good question that I've been sorting through lately. I'll post some more info later this week. I'm traveling right now but have some ideas to achieve this. I like your idea of more fine grained control of the your camera. I've been wanting to do the same with my Canon S110 and other cameras that I put into my wing.

Totally! I've been thinking about a cellular modem would be cool. Even if it could grab images from the PI and upload them in realtime. Hadn't thought about streaming FPV. That would be interesting :)

I need to know a little bit more about your setup. Is there a telemetry module connected to Pixhawk? If so you should be able to connect your Pi to another telemetry port and get MAVLink out of it.

if the command is not working, try "ls /dev/tty*" with you ardupilot device unplug and again after you plug it back, you should have a new ttyxxxx device.

Good tip. Thanks for sharing!

I will cover this in more detail in an upcoming video. Thanks for the good questions.

Definitely possible based on the documentation I've read, but have never implemented this before. If I can get some free time I'll put together a tutorial. Thanks for the question and good luck with your setup.

I'll need to look into this. I haven't been able to do any image processing yet, but definitely plan to. Let us know if you come up with anything. Thanks.

Good question. I haven't found a good way to do this yet. Right now I've put my script on a delay just for testing purposes. You can see it here: kzfaq.info/get/bejne/aMWcp85m09e7hJ8.html I'm looking into a way to use my RC channels to start/stop a script, but haven't figured it out yet. Will share more details as I research this. Please do the same.

Thank you for responding. Some one gave me some ideas such as checking my internet provider and firewall settings. I am going to try different things and if I figure some it out I will share it with you. Thank you for the other video you sent me.

The telemetry radios definitely are the way to go for traditional command/control. Regarding OpenCV and accessing the image data I'm not sure what the best approach is at the moment. I have a similar need and will continue to research and share my findings. Let us know if you figure anything out as well. Thanks for the question and wish I had a better answer.

Version 2. I've never used V1 so I'm not sure if that's a known issue. Please let us know what you discover.

I have limited experience with Edison but would really like to get more familiar with it. Thanks for watching and I appreciate the feedback.

Glad to hear that. I hope you enjoy it and please let us know how it works out for you.

Hi Dennis, Thanks for this very good video!

That sounds like a great project. Please keep us posted on any progress!

+Dennis Baldwin yes, for sure!!

That's a new one to me. I haven't seen it before but this thread talks a bit about it: groups.google.com/forum/#!topic/drones-discuss/I8sGdE-g8I0 Please do let us know if you figure it out. I'd be interested in learning what's going on.

I'll have to take a look at this as I'm not really sure. It's been a few months since I've messed with this setup, but I plan on revisiting soon. I'll share what I find out and please do the same if you figure it out first. Thank you.

Thanks for the reply, I think I have found out how to enable the serial channel on the newest version or Raspbian jessie. I don’t have it in front of me now but if you click the raspberry in the top left corner of the desktop it was under preferences or system settings. Basically its in the same screen to enable ssh and VNC. I still need to find the parameter for the serial ports on the pix-hawk to get it to work. Did you do this too. I noticed this step was not in your video.

Update, I think I got it workings with out changing any of the prams. I think there is an extra space in the documentation for the code to install on the pi 3. I copied and pasted from git hub these lines in the link. github.com/bduva002/ardupilot_wiki/commit/4264da1884e3dd835de864ebea316b76e4c65059 . Now I just have to figure out why the modes wont change. when I type mode RTL i get argument is not a float or it is unknown.

Strange. It almost sounds like something is wrong with your RX line where responses are coming back. I'll give it some more thought and let you know if I come up with anything. Let us know if you figure out anything from your end. Thanks for the comment.

if you use APM you must add --mav10 , it will be mavproxy.py --master=/dev/ttyAMA0 --baudrate 57600 --aircraft MyCopter --mav10 explanation in here : ardupilot.github.io/MAVProxy/html/getting_started/starting.html

Thank you for the kind words. I don't have any experience with either of those hardware components, but sounds like a really cool project. I've seen both of them and have wanted to mess around with them. Please keep me posted on how your project goes.

I made it by splicing together the FTDI and telemetry cables. It would be nice if there were a source that sells them.

@SERGEN ERBAY hi, i did solve it but i dont know how. I followed the instructions on the mavlink site. I did it like 15 times and one of them actually worked. I did the same 15 times so i dont know what went wrong. The cable was also loose so maybe that had something to do also.

@SERGEN ERBAY sure, guixermo94@gmail.com
