In this lesson, we'll be adding a camera to the design. After completing this lesson, you'll be able to insert a design and ground a component. At this stage in our design, we've already created the aesthetics, we've made the main part of the body, we've added our generative design features. Then, we've included mechanical aspects, such as the I-beam structure, the component tray which is structural as well. We did a simulation of this and we started to take a look at creating assembly mates. So we have the joints to let the camera move up and down as needed. At this point, we need to make sure that we include the camera in the video transmit module. Because both of these are outside of the component tray, we haven't approached them to this point. But we need to make sure that we have features that can hold them in place before we 3D print the body. Before I go any farther, I want to make note that the DYS motor that we originally inserted, and the second one that we inserted, both have a pin icon on them. They're grounded so that they can't move. All the other components in this design are actually still free to move. So I'm going to select them all, I want to right-click and I want to ground them all. So this way I don't accidentally move them around. Even though we don't have references for instance to the bolt holes, we could potentially cause a problem there. And also notice that the XSTAR itself, is free to move around. So we're going to right-click, and we're going to ground it as well. So now that everything's grounded because in this instance we don't really have a lot of joints or assembly motion, other than the propeller spinning. We can be sure that we're not going to accidentally move components around while we're trying to place additional things in the file. Now let's go ahead and expand the data panel, navigate to the folder where you located all the components. And we're going to be taking a look at the FatShark 700TVL camera that we used in the last segment, where we talked about assembly joints. And we're going to be using the Video TX Module. Let's start by dragging and dropping the Video TX Module in. I'm going to minimize the data panel for now, and we're going to take a look at this from the top view. I'm going to rotate this 90 degrees and in this instance it’s going to be minus 90, and we're going to come around and we want to place it at the back of the design. And we want to place it roughly centered. It doesn't need to be perfectly centered, because the antenna doesn't come out of the back of the board centered. It does help for weight distribution. Now, this is a fairly small component and it doesn't weigh a lot, so it doesn't make a drastic effect on the overall design. Now what I'd like to do is, I'd like to have the antenna sticking out of the back, and this helps us in two different ways. The antenna itself can swivel and it can pivot, so this way we can have it pointing straight back. That way, if we need to fly up close to a ceiling or some sort of obstruction, that we don't get it caught on anything. And it's also easy to put on and remove if we need to. So now that it's in roughly the right location, we're going to go ahead and move it up. And as we zoom in, The steps in terms of each time that the snaps in moves up will change. So the closer we get in we're at one millimeter, if we're farther away, it'll go up and down five or ten millimeters depending on your distance. So right there it looks like it's just about touching the body, and I think we're going to leave it that, 66 millimeters, we're going to say OK. So you can see that there is a slight interference here, and this is actually the connector that we're going to plug into. So if we rotate it around, the other portion of the body is flat but there's a connector there that we need to account for. So we're going to go into Modify, Move Copy, we want to change this to Components. And we're going to move this down, important note here that we want to capture the position, if we don't it'll revert back. So now when we take a look at it, we can see that we have enough clearance for that connector and we just simply need to make features that can hold it in place. So we'll say OK, and now we have the video transmit module in place. So next, let's go ahead and add the camera. Again, we're just going to drag and drop it into our design. I'm going to minimize the data panel, and we're going to look at this from the top. We're going to rotate it around so that it's minus 90, and we're going to drag it forward. So we're gona have it in roughly this orientation. And the reason I say roughly is because we need to position it so that the camera can move up and down without hitting any obstructions. So when we look at this from the right, we're going to have to move it up. And we want to get it close to where this upper body here is close to touching the main body, because we are going to be using that as the mounting point. So we might need to move it up just a little bit more. And that's going to be a bit too much. So let's try 21 millimeters, all right. So it looks pretty good right there, and it sticks the front mounting point for the servo out just a little bit, so that way we have enough room for the camera to pivot. We're going to say OK, and note that in the browser, we have the video transmit module and the FatShark camera. Now neither one of these is grounded, so they are free to move about. And there's some interesting things that we need to take care of here. Now remember we don't need the pan servo, we only need the tilt servo. But with the design here, it's linked so that there's nothing that we can do other than hide and show them in here. So that'll work out okay but the main issue here, is that the joints will not work out. So we have to be careful because we want the joints to work out, but we need to make sure that we're not accidentally panning as well as tilting. So inside of the tilt module, we're going to expand it, and inside tilt servo, we're going to expand bodies, and notice that we can't turn these on and off. That's okay because it's really for visual reference but if we want to hide this specific body, we'll have to go back to the original file. What we're going to do is we're going to take this tilt servo, we're going to right-click on it and we're going to ground it. Now, this is a sub-component inside of this top-level tilt, inside of the FatShark camera. But with this one grounded, we can now move the camera up and down without worrying about panning left to right. So you want to make sure that you go in and you ground the tilt servo. And that way the camera's going to be in the right location. And we can analyze whether or not the camera can move up and down and give us the range of motion we need. Once we're happy with the location of the transmit module for the video signal, we can go ahead and ground it as well. So for right now, I'm going to go ahead and ground it so I don't accidentally move it. And then I can save my file so we can start building the mounts for both of these components.
