Ball joint for an arm?

The part is actually featured in the Battlefield promo if you look closely, but it's not part of the turret which has been removed now.

any ETA on next openDog update video? :-)

Andy Ihnatko

Standard rear-bumper ball hitch, so openDog can pull a camper? Sounds ambitious, but I like your energy...

Yep - this video, should be up early next week for Patrons. The CAD and Code is already on Github

Can you link the github please, the openDog I see was last updated 3 years ago, TIA

Can you please help a confused me, I see .stp files not .stl. When I download and convert them to .stl all I get is one part, looks to be a hip part. What am I doing wrong? Why do you post .stp files instead of .stl? You use .stl files to print too don't you? Also what are the HUGE files of numbers, does CAD read them somehow? Thanks again.

The STP is the whole assembly. You'll need to load them into some CAD software (like Fusion 360) and then extract the individual parts for printing from there. The STP is a 'solid model' so you can easily modify the parts. I'm not sure what files of number you're talking about - that's probably the structure of the files? Just use the big green 'Code' button and select 'download Zip' to download all the files in one go.

To me it looks like new shoes for openDog.

Thanks, I forgot, probably asked this for the sonic hedge hog. Sorry. Are you happy with opening now, can I start printing or should I wait ? 🤔

Well yes it works, although I'd recommend getting to grips with ODrives first if you haven't already. There are a few overall caveats mentioned in the video, but ultimately it walks quite well.

What am I doing wrong? All I am getting is a dog bone, the gearing drive and an odd looking thing. Shouldn't I be seeing the entire openDog in Fusion 360?

Have you unzipped and uploaded 'openDog V3.zip' ? (the file was too big for Github so I had to zip it)

Anonymous

I think so, I chose the Green button and got 4 files, bone.stp, openDog V3_foot.stp, openDog V3_internals_toleranced.stp, and Remote.stp. Bone has only a dog bone, foot has a foot maybe, remote has the remote, and internals has the gear drive, 8 parts.

never mind, I found it, a zipped folder inside a zipped folder, tricky guy you are.

XRobots
>>72932728

Yeah - that one is the only STP that's zipped because it was too big to upload.

one last question, I promise, for now anyway ;-P Is there an easy way to export one part at a time without having to delete all the other parts in Fusion 360? If I highlight one part and export to an stl I still get every part on the screen in one stl file.

XRobots
>>72932728

Yes - go to the tree of the parts on the left hand side, find the part, right click and 'save as mesh', select STL from the dialog and what ever other options, click ok and save.

You da Man, thanks! You think I ask too many questions now, wait until I get this puppy all printed and start building, I'll be the first Patreon account you ever canceled! 🤔

I'm guessing a 3D printed flask for casting rubber feet.

The big parts are around 3 perimeters and 15% infill. The smaller parts like the Cycloidal drive internals need to be stronger, so 4 perimeters and 20/30% infill.

dumb question maybe, why are the lower leg parts so short, most robotic "dogs" lower legs a much longer. Stability issues? Have you tried longer legs and it went bad?
