课程 5（共 5 门，Specialization CAD and Digital Manufacturing）

Designing a product is only part of the process. Now, can that product be manufactured? A CNC machinist works with computer numeric controlled (CNC) machines from generating the machine code to machine setup and run. Understanding both CAD and CAM is essential to this portion of a design. Even if you are not the end user who programs a machine, it is invaluable to know how it’s done. This knowledge translates directly to part design by helping make intelligent design decisions with manufacturing in mind. This course introduces you to the integrated CAD/CAM approach behind Fusion 360 CAD/CAM as well as 3D printed design setup and finally assembly and testing. All stages of product design in one place! After completing this course, you will be able to: • Explain the Fusion 360 integrated CAD/CAM manufacturing workflow. • Summarize the trends that are influencing the future of manufacturing. • Demonstrate knowledge and skills in foundational concepts of Fusion 360 CAD/CAM software. • Set up a Flight Controller. • Assemble a quadcopter. • Fly the final design.

Quadcopter Assembly

You finally have a complete design and all the parts in hand, now what? This stage of the process can be a rather large task the first time through. From complex wiring, cable management, and overall assembly, we will step through the process. Even if you aren’t designing and building your own quadcopter, this is great information to have for when you do.

In this lesson, we'll take a look at power distribution boards.

After completing this lesson,

you'll be able to identify areas of a power distribution board,

and understand some PDB options.

Power distribution boards are an important part of any quadcopter design.

We have three here that we're going to talk about but there several on

the market available depending on the functionality you need.

The first one we have here is a Maytech,

and this one is a power distribution board with

an integrated XT60 connector that can plug directly into one of our batteries.

Now this one at the very basic level,

allows you to send power out to each ESC that allows you to bring in 12 volts,

and condition it down to five volts so we can power things such as our camera.

Most power distribution boards will have the BEC,

or battery elimination circuit,

to the point where you can condition the voltage down to a certain amount,

five volts and 12 volts.

Most of our components are going to be running directly off of the power from here,

but we do need to condition it down to five volts so we can power our camera.

The next power distribution board we have here is the Spedix.

There's also another one on the market that's very similar to this made by Turnigy.

Now this one is nice because it allows six ESC outputs,

and it has bullet connectors on it.

So, this means that it's completely plug and play.

You also notice that it also has

some harder pins for our five volt and our battery voltage.

So, we can take this power directly out to

power our flight controller as well as our camera,

and we can take out the 12 volt signal to power

our transmitter for our video signal back down to our ground station.

Units like this notice have two different sets of bolt holes.

The smaller set of bolt holes matches

the Maytech as well as the one we're currently using in our design.

These are nice because this bolt pattern lines up with a lot of

flight controllers that are on the market such as the full size CC3D.

If you don't have any experience with soldering,

an option like this is great because you can plug your ESC's power directly into

these as well as the connectors going directly

to power your flight controller and your camera.

The unit that we're using is made by FPD Racing.

Now this is designed specifically for

the CC3D and has one additional functionality that we like to use.

And that's something called an OSD or an on-screen display.

This specific board allows us to take power out to six ESCs,

so we can control up to six motors,

and also has conditioned power for things like five volt or 12 volt.

But in addition to that,

we have the ability to take power out to a camera,

take the video signal into the board,

and then take the video signal out of the board to our video transmitter.

The reason this is important is because this board has a small package size,

it uses that same 36 by 36 the Maytech did,

but it also allows us to keep the package size small and

use that on-screen display functionality that the other two didn't have.

There are plenty of power distribution boards on the market.

Several are actually integrated into chassis,

more have additional functionality than this one.

So, keep that in mind when you're planning your build to look around at your options,

so that way you can pick the best port for you.
