Just finished building this amazing project and helpful tutorial you are a really guineas thank you

What is the precision like on the movement? How fine can you adjust it's positioning?

can u explain the DOF for each motor & the mathematics of the project ?

That's great, good job man!

Hello, I´m a teacher on a High School in Germany, exactly in Bavaria. I´m very, very impressed of Your project and I want to make it with my pupils. Is it possible if You press the button on the gripper and simulate a movement with the small robot included the potis that the robot can repeat this movement automatically? Is there an additional button necessary for save and repeat the automatically movement? Kind regards Michael

May I know the dimension of the used gears? I am planning to also 3d print the 40T and 34T gears

The background music sounds like a bad word

I can't find the filament, its gone :(

Hey I have rewired this 3 times now and it just cant get it to work any tips will help thank you

Nice design good explanation But i think its better to use stepper motors instead of potentiometers. Stronger.!

👏🏻💯

Can you make a new tutorial just about the wireing for begineers😊

5v 2amper güç kaynağı yeterli mi ?

make sure the max current your 7V power supply provides is enough to power ALL servos, the arduino and plus extra for losses from wiring.

WHO TF ARE YOU? BECAUSE YOU'RE A GENIUS! THANKS!!

Keep at it!

hello, i decided to make this project, and i started to buy the pieces, print the parts but icant find the code. someone help me? i cant see the code in printables(sorry for bad english, (from turkey))

Cool stuff! What speed and power do you use to cut cardboard? Just got my pro2 and was looking for some settings!

Awesome presentation Kelton

I noticed one of the wires isn't the same as on the diagram

First of all i wanted to thank you for the thorough walk through and the detailed explanations. This is my first "big" project in electronics i am doing. I have a small question that might come off a bit unknowledgeable. For this project i need a power source/supplier. How do i pick my power source? Do i get a battery? an adjustable power supply (that seems the best choice but also most expensive). How do I know what Voltage and current i need to supply in this type of project? Thank you very much!

dope

Hello, excellent video. I would like to know where I can get the 4 gears or if you have the stl to print

Hello, the maximum voltage for the pca9685 (servo driver board) is 6 volts yet you still supply it with 7, how?

everything works but only 2 servos move but when they do they twitch. idk why and iv been trying to find the probem for a while now but i cant

hey dude, awesome stuff. Just wondering what can you change to make the join movements smoother and more accurate?

Hello, I’m Abo it to put everything together. Just wanted to ask, when you plug the Arduino in to upload the code, do you also plug in the power supply at the same time so the servos work, or will that be too much voltage and fry something?

I just came across this video and was really impressed with the in-depth review! I really look forward to watching your other videos!

AWESOME project! the best robotic arm I've ever seen on KZbin. The description contains a file with 25 3D elements is that all that is needed to build it?

May I create it in PLA using Printer 3d instead of Laser cut converting File F3d

I'm finally getting around to posting about this lol

I got this working, but my hand servo doesn't move and the smaller arm with the pentiometers doesn't move the bigger arm unless I hold the button down, when the button should control the smaller servo for the hand. Any ideas where I went wrong?

Hi Kelton lol

Hello Kelton! Congratulations on your world record! 🥳We would love to do a story on this. If you are interested, contact us at [email protected].

great and easy to follow tutorials. Do the servos need to be 360 degrees? I assume yes, but just making sure

this is a late comment so I'm not sure if you'll see it, I was wondering what you did for power, other than "connecting it." I think I understand and am capable of building everything else, as you layed it out quite nicely! I'm excited to build this as my first project with my new printer, thank you!

does the middle gear engage both gears left and right?

how much power are we suppose to give the system?

Hello, great project and I’m very interested in building it, however I am struggling to find the wiring diagram on the link you have in the description

First electronics project...... I think ive blown 2 servo boards. Had the servo boars plugged in while uploading code to the Arduino Could this jave overpowered and blown the board?

Me and a couple friends managed to assemble this whole thing for a school project, however we're running into an issue where when we upload the code, none of the other servos move as the potentiometer does. We tested all of the potentiometers' connection without plugging into the servo driver and it reads, but as soon as we hook everything up to the driver only the microcontroller for the gripper functions properly. Some help would be greatly appreciated, thanks for the great tutorial!

muy bueno gracias voy a intentar construir uno

I've built the project. sadly its not working as expected currently. only the base servo and the shoulder servo and hand servo are moving in response to the controller. however the movements are a bit erratic, some movement mimics the movement of controller but then the servo will move the other way and sometimes the servo is sort of twitching even when the controller is perfectly still I have tested continuity for all the wires coming from the pots right to the arduino so ruling out any failed connections. Also the hand servo is constantly in motion until i press the button and it stops until i release again. i'm assuming i've wired this the wrong way round. i worked around this by changing the code to if(pushbutton == HIGH) instead of LOW Has anyone else had similar issues? I'm new to wiring and electronics so any help would be appreciated. Is there any program i could use on my arduino to see if my arduino is picking up the changing values of my potentiometer signal. Many thanks

Potentiometers?

I currently want build a robotic arm but i dont have a 3d printer. Do you know if theres a way to build my own without a 3d printer like i can buy all the parts somewhere thats also cost effective?

Thank you so much for this video! I've learned so much and you are amazing for keeping this open source. I'm super new to electronics so I ran into an issue with the micro servo for the gripper. When I press the button the servo doesn't move. It will move the 90 degrees to close at the beginning (line 28 of the code) but won't move beyond that. When I switched it out with a regular servo (MG996R) everything ran fine and the button opened/closed the gripper. Plus the pin 13 test light turns on/off when the button is pressed, so I'm confused. Wiring isn't the issue either since when I connect the micro servo to the pins controlled by a potentiometer, the micro servo runs perfectly. I've tried to troubleshoot: I've assigned the micro servo to different pins on the driver board, re-copied the code over, and, checked the voltage with a multimeter (it was within the correct range for the servo), but I'm still sort of stuck. Any help would be appreciated. Thanks!

how many volts/amps should be supplying through the t plug? many thanks

It still doesn't work, if I only plug in the Power the driver doesn't turn on, but I've tested it with an LED an there is power, but the driver doesn't turn on. But if I plug in the Arduino the driver turns on but the voltage is missing an the servos do nothing. Could anyone help me 😢

nice work👍

Hi, thanks for the review. Is it engraver suitable for PCBs?
