GimBALL - 3D printed DIY Gimbal with closed hull - PART2.5 (integrating) + STL files!!! - Blogs

Hi,

I continue my blog with the integration of GimBALL into the nose of an X-UAV Talon.
Because of complexity and available space in the Talon's nose, I decided to build it with 2-axis stabilized setup.

I hope I'll be able to test it in the air soon, and will share some test videos. Till then, here are some sample images about the current state:

Regarding STL files, finally I decided to share them at GrabCad.
If you like my work, you can donate me with some bucks too!!!

Please note that this is an experimental work, and maybe need some modifications, adjustments to successful operation. Use my files on your own risk!!!

Here are the suggested motor types again:

on pitch: HK-2206-140KV
on roll: RCTimer 2212
regarding yaw, my first thought was RCTimer 2804 hollow shaft, but initial testing shows that it is not strong enough. So I made a modified arm with flat top too (rev2 files), so much more big motors can also be used

Please note also that I'll not modify GimBALL for any other cameras than MobiusHD because design process needs a lot of time and I'm doing DIY things in my limited spare time. Sorry HERO users. Please do not ask me, I'll not reply to these. Thanks for understanding!

Next time I'll show you some sample videos! (PART3). Stay tuned!!!

I'm looking for other projects like this. I must build a gimbal (2 or 3 axis) to be mounted frontally. Any suggestions, please?

Thanks.

Divya, I can't really understand you. all motors have proper mounting places and holes.

MD, use smart support and it will reduce the amount.

Hi, I was using this orientation for printing.
Adrián Nagy Hinst January 13, 2015 at 9:01pm

MD, I'd suggest to give a try on the small HK motor on pitch. Not as expensive...

Using the bigger motor on pitch shifts the Mobius CG, so probably you should add some extra weight somewhere to balance the gimbal.

This vapor bath makes surface snmoother, I like it. Fot the top element I'd suggest to rotate 90 degrees in printer like the bottom one. Then the "printing lines" would go together with the cylindrical surface, giving even smoother surface. I'll make a suggestion soon.

Hi,

Toby Lankford, yes orientation is important! I designed the parts for a specified orientation since FDM printed parts are quite anisothropic! I'm interrested in your printed parts, you could share some photos or send me by mail. Of course, feel free to share your positions too.

MD, sorry I wouldn't share the files. Send me an email with your type and dimensions of motors, I can modify parts uppon them.

Excellent! That's great that you're releasing it. Once I get my printer up and running again, I can take a stab at it.

awesome!

Awesome job. As soon as my 3D printer arrives I will have much work to do. Thanks again for sharing your files.

Hi, with the suggested pitch motor, Mobius, an average sized sensor plate it is in balance around roll/pitch. Balance in yaw can be adjusted within 7 mm range, with the suggested roll motor it is almost in the center of this range.
Also using of thin wires is important. Wiring suggestions can be found in PART2 of my blog.

Thanks soo much for sharing.
Have you consider balancing every axis on the design?
