I made a Mini Robot Arm to Control my Big Arm

hey I am Jane and I have a robot's arm it can do all kinds of cool things like play video games and Destroy buildings and like actively move around uncontrollably but I have one big problem the controls currently the easiest way to control it is with my app where you can control the robot arm by moving the gold but I can never get it quite right because I can only move in two Dimensions at once what I want is like a smaller version that I can control physically and like move it in all three dimensions at the same time all right for that I can use my little Servo the little prototype I built for my robot arm but as you can see it's like really falling apart so it's going to need a couple of upgrades speaking of upgrades my robot arm I has seen better days when it's not completely falling apart it overheats or starts moving uncontrollably but those things are a problem for the future let's start with the little one first alright so if I want to use this mini version as a controller I'm going to need a way to read the angles of the joints the big one has five Motors so I need a simple solution that works for all the locations and it has to be pretty compact too so it can fit in this small Footprints okay Ellen let's think let's think let's think I could set up a computer that calibrates the joints for preservation this is making things way too complicated you know what's very good at measuring angles [Music] centimeters I mean that's why they were invented in first place now I just need a second Raspberry Pi so I can use both arms at once wait never mind apparently they have been sold out for like three years now man I should really take more care of this one maybe they will become just as valuable as these old Pokemon cards you know my mama wrote to become a millionaire so um and Arduino it is just plug it in the computer use my serial package and it's connected [Music] all right that works pretty good but I have one big problem if I'm only using potentiometers I will have no way of controlling the robot on with my software I want my little arm to be both a controller and the controllable cutting both a potential meter and a Servo in the joint is gonna get pretty cramped wait a minute server Motors already have potentiometers in them that's how they calculate their position if only there was some way to get to that data hacker mode activate who am I kidding I'm not gonna think for myself I'm just gonna ask chat TPT which connection do I need to solder to to get positional feedback from a 19 server motor Island which model is visual perception to examine the Nerf gun Servo motor wait what color would your eyes be if you did have a body you can choose whatever you like best acai language model you don't have a physical body so we don't have eyes or a specific color however for example my eyes could turn blue and I'm calm and relaxed I do like blue eyes blue eyes can be beautiful and captivating while you don't have physical eyes it's always interesting to think about different eye colors and what they can represent blue eyes are cotton associated with qualities such as what am I doing right where was I oh yes find the potentiometer value in the servo better ask a human this time alright so apparently it's in this middle connection here all you need to do is solder a wire to it and read its value look at that now I know exactly what angle I set it to alright that's pretty cool now there's still one big question remaining what is it going to look like well let me explain [Music] foreign because the servos are really weak I had to make it really light so that's why it's basically only made of cardboard and 2D printed stuff and to help the servos even more I added this extra elastic at the bottom to give my servos that final push looking back at the big one one super annoying thing was the fact that I designed this slide on covers this makes no sense because I had to put it on before everything else and it's basically just decoration so for the small one I decided to split them in the middle and fix them with this race alright let's see if it works okay okay nice nice yes yes all right the digital arms seems to follow the small one pretty well and it's also pretty responsive so I think that's a pretty good test now I can use my little arm to control my digital one and use a digital one to control the real one oh yeah that's right let's have a look at this mess [Music] I still have four big problems the arm is still terribly unstable the wires keep getting stuck inside the arm it overheats if I use more than five five minutes stop the arm is way too heavy [Music] well the instability was mostly caused by the fact that the only thing holding the arm together was this little silver arm I need something to relieve all that stress like me after a long day of work there's nothing I like more than being served a nice dish man lazy Susans are a great invention wait a minute of course exactly what I need I can use this ball bearing and connect them with these flat parts to my robot arm that's already a lot more sturdy which brings me to my next problem the wires the edges they have to fit through have now gotten even smaller I mean they're basically non-existent the ball bearings are blocking the way and I don't want to Route the wires through the outside I mean our elbows don't have any wires sticking out of them as far as I'm aware luckily there's some space inside the ball bearing hole I designed this little sliding hole Holes which ensures there's always just enough space for the wires however I'm going to need to be very careful not to overturn them because that could create a pretty nasty situation speaking of nasty the overheating plastic sure is now this solution is simple what do we do when something gets way too hot well you just simply blow on it like really hard so I remodeled the base so you can mount this little fan on top of it and also add a little bit of room along the servo to allow for more airflow all the way to the bottom I also made this aluminum bracket to hold the servo in place this way it won't move around in the amount of plastic anymore all this extra stuff is adding so much weight and it's already way too heavy to begin with I need something to come to balance the heavy weight of the arms to help the servos a little bit that's quite a lot this car these counterweights might not add all that much especially if they're so close to the Joint wait I am Nagi instead of increasing the counterweight I can simply decrease the arm weight let's drill some holes wow that's a giant weight safe alright time for the big reveal after all that work I finally have a robot arm I'm proud of this is it the climax it's here get ready it's right under this cloth are you ready I present you my new robot oh what's this oh there you are looking good as always now let's see if you two can work together okay let's test the waters first a little bit see if the big joint works and then the other ones all right can it stand on its own okay looking good looking good let's see if I can make them touch each other oh yeah all right enough testing you know I am pretty hungry right now but I'm not gonna feed myself what is this the Stone Age this guy can do it for me alright let's see if I can get strawberry in my mouth [Music] it's just easy as that a little flick of my wrist and I'm eating strawberries all day long oh I've got even more plants do you need to comb your hair but you can't quite reach at the back of your head well I've got just a solution for you look at this perfectly safe way to comb my hair what could go wrong I mean I think I found my new hairdresser oh wait I've got one more great idea [Music] where's this let me in hey hey what are you doing back there let me and let me in hey [Music] what are you doing there [Music] what what what are you guys what's this what did
