ArduCopter Frame development

We all are working hard to get this done as soon as possible. And as relief the pain of wait, here are some previews of new ArduCopter frame designs for the masses to look and to comment.

Current design will have two center plates like most of multirotors have, it also have carrier boards to carry electronics like APM, APM shield and Receiver. Another carrier board will be mounted under main frame to be as a battery holder it also creates supporting base for future landing gear addon.

It's been planned to have a power distribution board above center plates.

Square center plate having X setup, it also holds + setup on this board


Center plate with carrier board. Carrier and also power board (not shown) can be rotated with 45° steps on all designs. Power board will have 10 mm spacers and carrier 20 mm.


Square frame with carrier (rotated +45°) and power board.


And last but not least round Quad/Hexa center board. Quad power distribution included. Both carrier and power boards can be mounted either above or below center plates. They also fit on both square Quad plates and round Quad/Hexa plates.


We are closing finishing line so not any major changes should happen. Tho this is still preview on what we have been working behind the scenes.

First frames are being build as we speak..

I will post more pictures on development wiki https://code.google.com/p/arducopter/ during new couple of days.

Cheers,

    Xander, this is totally DIYDrones project. Me and few other are DIYDrones core group to develop ArduCopter based on DIYDrones ArduPilot Mega board and latest OilPan IMU shield.

    There is now about 10 people developing this and our leader is naturally Chris :)

    Our projectpages can be found from Google code https://code.google.com/p/arducopter/ and there is also list of current main members (tho i should update it a bit but been busy :) )

    Currently our group has every aspect rather well covered and we try to get first release out as soon as possible and not really looking new members but you are always welcome to send email to us :)
  • Jani, is there currently any way to get involved in this project? I've seen a few posts about it now, but I'm not very clear on whether this is one of DIYDrones' group projects or just something you're doing with friends.

    First 3D parts was just posted to SketchUp 3D Warehouse. If you want to play with frame and maybe start building your ArduCopter. You can download this center part from

    http://sketchup.google.com/3dwarehouse/details?mid=488437bbcd52dfb0...

    More parts will follow later. This is not yet final part but no major changes are expected to this design.
  • well even if its not foldable, could be possible to dismount it in an easy way, and mount it in a few minuts in the field ? way more confortable to transport it packed in a backpack or so
  • I would say to stick with the "PCBish plastic" Or G10, FR4. Its very rigid, and is quite cheap:

    That is 48"x36"x1/16" for $60, available in black, blue, brown, and a light yellow/green. Its simple enough to make that you wouldn't need to send it out, It cuts well with a CNC laser of at least 40W.

    We going to produce our own tubes for this as sell in package. It can be build with other sizes too. For example if you crash and bend one arm, it can be easily replaces even with bigger tube. Tubes like that your 12.7mm. Smaller are always easy to mount too.

    @Jhon well if we try to keep manufacturing cost low and on reasonable level. I'd say no it's not directly foldable. Tho with minor modifications model can be folded, depends on how cabling and other things are done.

    Cool, Jani! So, we can do that at the right time. Until then, I'll be tuned in the news.

    When you said 12x12mm, is the real measurement? Or are you rounding it? In fact, the smallest tube that I found here is a half inch square tube = 12.7 x 12.7mm. For make the design available for a lot of places around the world, maybe this measurement could be adopted. Imperial sizes are more common. Import the tube isn't so interesting, comparing with the other parts.
  • so it will not be foldable for easy transportation?
  • Developer
    square plate is 110 x 110 mm and round is 130 mm diam. Booms are 12 x 12 mm alu tubes lengths around 18" and 24"
  • what are the dimensions? are we still thinking of use heli boom tails or square alum tubing?
