all right so now we're going to mount our create the holes to mount our batteries and our control boards and our camera and a motor controller and so we're marking the holes for our battery now and the holes for the batteries and the motors are basically allow zip ties to come through and they're there they don't have to be super precise you can sort of eye those and get pretty close so we're using about a quarter inch drill bit and time-lapse that so you can see all the holes there and now we're just drawing a line to kind of connect our the holes that are going to our motor so we can use that as a reference point for our lining up our boards and things of that nature it will put another line there so so we've got all our components here we've got our camera our motor controller and of course the Arduino and the outer housing and the lexan below and so we're trying to find a way to orient all of these on the board and see see if we can make them fit together so we'll put the lexan in place we're gonna put our batteries underneath and our motor of course goes on the side so we're just trying to get a feel for how these things are gonna fit together and we're just positioning them on the the lexan and so we've got the camera there and I think we're gonna turn the camera the other direction it's got some rounder corners which tend to line up better with the edge in that direction and then we could put the Arduino like in this direction so that the USB is the same side as the cameras USB and then put them maybe the motor controller on top of the camera so I think that's how we're gonna lay it out and we've also got a recording module it's a little voice module you can get from RadioShack and we're gonna put that we're not sure we're gonna put that yet but we know we can mount that in a lot of different places so right now we'll just sort of set it on top the Arduino and get a feel for the space so we're gonna line up Arduino and try and line it up with those those horizontal lines that we created so that it's it follows that and then we're gonna just outline the Arduino and the outline kind of just helps us to make sure that it doesn't shift around as we're drawing the center holes for our draw drawing the center marks for our holes that we're going to use to put our screws in and that'll hold the Arduino off of the lexan top there so it doesn't look like we're we're lining the marks up but we are it's just the angle of the camera the marks are directly over each hole really important again that those are lined up precisely because the screws are very small and the holes are very small they're not like the zip ties they have to be pretty precise otherwise it just won't fit so you can see our screw here that we've got it's a 256 machine screw round head machine screw you can get these at RadioShack I believe they're nickel-plated and they fit nicely through the Arduino hole and also the holes in our camera that already exists so we don't have to to make any new holes but we do need to use a drill bit that is just slightly larger than the threads on the on the screw and in this case that's about a sixteenth of an inch bit so we've already got our holes for the Arduino mark we're gonna drill those out and then just knock off the plastic shavings we're marking our camera here and again it's very important that the screws line up perfectly mostly because the holes in the camera and in the Arduino for the screws are very small and we're using our sixteenth bit to drill out the holes for the camera so now we're just positioning our Arduino we're gonna put our camera on there so we can create some new holes and we're going to locate the holes for our motors so those are motor wire holes and then we're going to put a hole for our on/off switch we're gonna find the location for that and these are not super critical I mean you can put these holes in any any place and this is the hole for our on for our battery power and we're going to put a couple random holes for power wires so we're gonna put a hole here and here for wires and then one up at the top there for for wires as well we may want to route wires in different locations and we're just marking that that that's the front of the of the bot there okay so now we're gonna take out our on/off switch and we're gonna look at the size of the the threaded shaft there and compare it to a drill bit make sure that our drill bit is the same size as the threaded shaft with the threads so that we can fit the on/off switch through the mounting hole very easily so again very important that that's pretty precise so we'll drill that that hole and and put the but the switch to mount the switch and then we'll also finish the other holes and this is what the final piece of lexan looks like you can see the whole configuration there yours may differ slightly obviously if you choose different components the holes will be in different locations so now we're going to connect our lexan peace to our styrene outer surround housing or chassis and we're going to use the original screws that came with the tap light to go back through the the the lexan and connect to the styrene housing so double checking our holes and our placements for our camera on the Arduino there and then we'll put all our screws in so it's important not to over tighten these screws because they will strip out in that soft styrene so we're ready now for our next video which will show us how to connect all the different parts
