 So this is my first attempt at animatronics. At the moment it's not animatronic it's just servo driven and I've got this remote control here set up where I can make this head move around and then in future I'm gonna connect it to a Arduino mini computer thing and program it to do some stuff. So the model is a plastic egg and some joints and a couple of servos there and there and a 3D printed base. I'm going to go through the whole building process name and you can see how it's done. Now here's these plastic eggs that I got from eBay they're just they're supposed to be able to hide treats inside them and then hide them in the garden and send your kids out looking for them and then this fine tooth saw I'm going to saw the end off at an angle like that to make it look like it gives it a chin on the bottom of it. So I sort of struggle away with the saw and then smooth it all out with the file like that and there you go there's a sort of head shape to start off with it's more it's kind of like a helmet at the moment didn't it. So for the nose I've used a wooden bead really carefully cut it in half and with a dotter hot glue fasten it into place on the front like that and you'll notice that I've put a black dot where the nose is. This is from sort of previous experience of if you don't know where it's going you end up sticking it all around the place. Googly eyes always make everything looks better with googly eyes so I'll pick a couple of googly eyes that are the same size. Peel off the backing paper off the back try and get the train use the sticky back ones they work best. They're easiest to use and stick the googly eyes into place and all of a sudden it starts to look more like a character you've got a nose and some eyes and it and the roundness of the head definitely looks like a character. There is an enamel here with a 2mm bit and I'm drilling holes around the outside of the model and getting off marks the place before I start drilling so that I know where I'm going. I've drilled these three holes around it and I'm going to fit three connectors that will hold everything together so this is from my packet of connectors that I bought from eBay. The idea of these is that these are from remote control racing cars part of the steering system I think but useful for this so it's just basically a ball joint in a plastic housing with the bolt holding everything together so take the nut off fit the bolt through one of the holes this is the hole at the back of the head that's in the nut into place tying it up and there it is so just to make sure everything's in place I just sort of nip it up with a pair of pliers and then I'm just going to do the same I've got two more of these connectors I'm just going to do the same on either side of the head and that's going to give me three connectors and that'll give me three points of movement for the head and then another two connectors this time I'm going to fasten them on to the servo arm I had to drill out of the hole in the servo arm because it wasn't quite big enough so I've drilled that out popped that on there here's my pliers to tighten it up and because I've ended up using two pairs of pliers on the back and one on the front just to make sure because the bolt itself was rotating so I've got a pair of pliers on the back there another pair of pliers on the front tiny open now that'll stop everything stop anything coming under and fitting the servo into place I'm using this servo tester so I'll plug my servo into there and by rotating the knob on the servo tester I can move the arm from side to side and what I want is for the servo to be in its sort of central position sticking straightforward and then as I turn the knob it goes from side to side like that and what you can do is there's a button on the servo tester you press the button on the servo tester it centers the servo and then you just plug it into place so now I've got two servos and I need to design myself a 3d printed base to screw them on to so I've sort of got a rough idea of what I want I've sketched it all up gone around the outside done it in pen just because you know it looks nice doesn't it and then I'm going to take the servo itself measure it up with my pair of calipers and make sure that I know what sort of size it is transfer those sizes to the sketch and then I'm going to use this sketch as a guide to build an actual base using Fusion 360 so this is infusion 360 there's my base these are the side arms and this is basically a top view of what the whole thing's going to look like so I'm just sort of constructing all the various different parts this is the hole that the rear of the head is going to connect to and I'm just sort of fitting that into position and making sure that everything's all lined up properly so there's the base top view and I will now rotate it around and extrude it like that so I've made it sort of five millimeters six millimeters thick of thing and then rotating it on the side so I can grab these pieces on the underside I'm going to extrude again like that and again like to make the arms and then that's basically I've made two cradles facing each other that the server will fit in put some holes in for the screws and that's basically that done so now that's a case of I need to export that into a format that can be read by the 3d printer so I send that into simplify 3d which is here and it just drops into place like it's quite satisfying the way it drops onto the baseboard like that and then I send that out to a SD card and I plug the SD card into my 3d printer and there it is time-lapse of it being made you can see it takes a while to do that you can just leave it while you're having tea or something like that and then there's the finished part ready to go and look at that it fits very satisfying when that happens the servo sits into the tray into the little cradles like that a couple of screws secure them into place put the other servo on the other side couple more screws and then that's the hole that's the base basically assembled and then to join the head onto the servos what I'm going to do is use cocktail sticks and they're there because they've got tapered ends on them they make a nice taper fit you just sort of push them into the connectors like that and I can move them around so sort of jiggle the parts around like that I'll make them look around hello making lock from side to side and we're going to fit the other end of the cocktail sticks there one to the rear of the board and then the side ones to the arms of the servo like that and then a quick test and it works and there's the finished result so what I'm going to do now is I'm going to work out how to program this servo so that I can make it tell the story without having to sit and twiddle the knobs myself thanks for watching hope you liked it bye
