ESP32 Robotic Arm Build Video Guide! (ACBR Open Source Robotics Kits)

hey you guys want to build a robot so I feel like building a small Rover and a robotic arm are some of the first projects that a lot of makers out there do and for good reason it can be so much fun to build a you know 5 degree freedom manipulating robotic arm it's also so much fun to start to see your projects roll around on their own you know you can add autonomous sensors Bluetooth control all kinds of fun stuff and so it was really important to us to include a really awesome high powered robotic arm on a lot of our projects that's why the Voyager Explorer and our robotic arm kit include a really strong high torque all-metal robotic arm and this video is all about how to put it together let's get started first things first we've got to talk about the tool so we're gonna be using now it was really important to us that we included absolutely everything you need starting with the screwdriver we also have an m3 m4 wrench we have this awesome T tool for m3 and m4 s and of course an m3 allen wrench next you want to grab the bag labeled bass that's gonna have everything you need to start building your robotic arm we're going to start from the bottom and work our way up step one is going to be attaching the aluminum bracket to the PCB of your Voyager or Explorer I'd recommend hand tightening these first but once you have them hand tight you're gonna want to use your allen wrench and your t tool and get those good and tight next we'll be attaching our servo be sure to grab the D s 32 you're also going to want to make sure that the actual shaft is facing the right we're going to use the exact same m3 bolts in the exact same m3 lock nuts for this part as well there are a few right ways to do this I usually like using the open-ended wrench like I have here and the allen wrench to make sure these get good and tight our next step is going to be attaching the aluminum servo horn but before we do that we need to make sure that the servo is in the right position so what you're going to want to do is make sure that you plug in this servo into the spot that says servo one on your PCV you also want to make sure that the data line or the white wire is facing the left because we have the program pre-loaded once you turn on the PCV turning on your Voyageur the server will automatically go to the correct position once you have that figured out you don't want to make sure you attach that aluminum servo horn making it as straight as possible just like we have here once you have the servo horn attached go ahead and tighten it with a screwdriver all right the next step is gonna be grabbing the bag labeled servo to be sure to keep an eye on those four little m3s that we didn't use from our last bag now this bracket is the exact same as the previous bracket we're going to attach it to start to create our servos that will let our robotic arm move forward and backward make sure all those m3s are good and tight and you're ready to move on now we're going to be placing the D s 32 in this bracket just like the previous one but before we do we have a very important step now the shaft is going to be facing the right here before we attach the servo we need to attach the bearing to attach the bearing we're going to be using the m3 that's silver but longer than the other m3 is in your kit we stick our slightly longer m3 through here we have our bearing making sure the larger part is facing towards the bracket and we attach the lock nut now here it's really important that you get this tight but not too tight you want to make sure that the bearing can actually freely rotate just like that you're all set alright next we're going to be attaching that DS 3200 the process is going to be the exact same as before make sure everything's good and solid not wobbly now next we have to make sure that this servo is in its start position and so we're going to do the exact same thing we did for the other servo except this time we're plugging the servo into the spot that says servo to stop making sure that the white data wire is facing the left turn on your robot and the servo should move to its starting position once you have that taken care of you're gonna stick on the aluminum servo horn and attach it just like you did before now we're going to go ahead and take the u bracket stick it over the bearing and over that aluminum servo horn line up those holes and attach all four em threes okay so at this point we're actually at our halfway point and what I usually like to do is test everything that we've done so far so this is optional but I recommend it's always a good idea to make sure that you're on the right track so grab the ps3 controller that came with your kit turn on my voyager press the center button on the ps3 remote to pair it and we're going to test the first two servos that we've installed if you have right and left forward and backward then you're good to go okay next you're gonna grab the bag labeled servo three you'll notice that a lot of these pieces look the same and that's that's the case the biggest difference here is that we need to integrate the l-bracket that's what we're going to use to attach the claw here in the next step other than that the process is really really similar our first step is going to be attaching the u bracket in the opposite orientation to u bracket that's already installed to do this you're going to use the black m threes and the m3 lock nuts you could attach these the way I am right here you could also undo the previous step to get a better grip on the m3 lock nuts but that's up to you all right now that we have the other you bracket installed we're going to go ahead and prepare this servo bracket the biggest difference here is we're going to have to first attach the L bracket before we do anything else to attach the L bracket you'll use the exact same black entries you you you okay once you have the l-bracket installed go ahead and install the bearing just like you did in the previous step next you'll install the servo this time we're using the mg nine nine six servos [Music] once you have everything good and tight go ahead and plug in that servo in a spot that says servo 3 and turn on your PCB to set that servo to the start position in case the data wire is yellow instead of white but the orientation is the exact same go ahead and install the aluminum servo horn in the exact same way you did in the previous steps now that we've added a second servo we can go ahead and test our three servos that we have attached so far now at this point I want to mention you actually have some leeway here so some people like to have the robotic arms starting fully upright here I have the servo facing forward a little bit but it's a hundred percent up to you all you have to do is unscrew the center bolt on the servo horn and you can adjust it to however you'd like lastly we have our claw now mounting this is pretty straightforward you're gonna notice that one side has cutouts for the m3 nuts and the other is flat you want to make sure that the side out the side with the cutouts for the lock nuts is facing you the bolts used to attach are the exact same black entries with the m3 lock nuts next you'll want to take your four and three lug nuts and place them in the holes that are cut out for those lock nuts after you have that all figured out go ahead and place the servo in the servo slot now be sure that the shaft is facing the center of the claw once you have for the servo installed you're gonna go ahead and place the servo wires into the spot that says servo 4 on your circuit board making sure the yellow wire is facing forward okay with the circuit board on the servo should be in the start position next we'll attach the claw this part is really really straightforward what you want to do is take both sides slide them in place and for this you're gonna want the claw slightly closed not all the way open and not all the way closed here to have it about an inch and a half apart once it's in place put the plastic servo horn on that shaft of the servo and you'll take one last m3 and attach it in a center shaft one final test in this case I use l2 and r2 to open and close the claw which can totally be changed in software just like that you are done now again this robotic arm is fully compatible with the Voyager Explorer also re also RESP 32 of robotic arm kit we hope you guys have a ton of fun with this we have lots more videos about some of the finer details coming out soon so thanks so much for watching guys have a great day
