Design Competition — Multirotor

[Anonymous]

Greetings all,

I had a thought today that I'd like to do some Fusion design competitions. I figured I'd throw one out there and see if people are interested or not. I have no prizes to offer, I see it as an opportunity to learn more Fusion tools and techniques.

BACKGROUND:

Multirotors are remote controlled aerial vehicles that use three or more rotors of equal size for vehicle control. They are used for recreation, video capture, and are very agile. Multirotor parts are available from hobby shops and they can be built in a home workshop.

Here is a video:

Here are some common layouts:

REQUIREMENTS:

• Must use the required (attached) parts, the Rotor Assembly and the Payload
• Must have a minimum of 3 rotors
• Chassis should weigh less than 1.0 pounds per rotor. (3 rotors = 3.0 lbs)
• Motors must be mounted by all four threaded holes on bottom
Payload must be located in the center of the chassisSee attachments for the files you will need!

EXTRACURRICULARS:

Please post a screencast discussing your modelling or design strategy!
• Please set the material for each part and record the total weight (The included parts have negligible weight)

REQUIRED PARTS:

Attached to this post as a *.zip file are the parts you will need; the Rotor Assembly and the Payload. Shown below are renders of the parts that have been attached. Look at the bottom of this post for a link to the zip file.

Have fun!

If you're having trouble importing these parts into your Fusion working file, try this:

• Upload the attached Archive files
• Open the file in Fusion
• Stop capturing design history
• Save

Now you should be able to import it, but the joints will be missing!

Great competition!

After import, it seems the model is a little changed because of the result of first pattern. I would suggest use "Pattern Feature" type here. It's better for this kind of patterns(faces from different features are merged). I attached a new one with the edited Pattern for those who import with issues:)

“Stop capturing design history” is a good workaround for issued parametric models in Fusion. Another one is "Convert To DM Feature" in Timeline right click, which will convert all Features in the same component before the selected Feature to a BaseFeature without history. For the following model, I just select the Mirror, and all Features in the same component before it will be converted together to a BaseFeature.

Thanks for the tip and reposting! I'm still learning. (I don't think it should have crashed Fusion, but I'm always glad to know a better way!)

Here's my first version... this was fun to model! Lots of tsplines..

[prabakarm]

Agreed, we should not crash.  We will be fixing that.

Hey Luke, if you're looking for a fun design competiton to be involved in check out the Megabot Challenges we're doing!

I totally will!

My take on it, I didn't add the joints in, but rotating the inner circle will allow the rotor assembly to be collapsed. I assume the Payload includes the necessary wireless communication? 😛

Fully modelled using T-Splines (good training I must say) except the round base that the payload is sitting on.

now as a serious student project what would be the cost for such components?
