How I Built a 3D Printed Robot Arm from Scratch (Arduino Based)

I made an Arduino based robotic arm with a unique control system for under $60! This video will take you through the design, assembly, and code process. My goal was to design an arm that was as compact as possible and didn't have a mess of wires coming out of it. I think this arm turned out pretty well!

I am a 73 year old inventor with 12 patents who has stayed up to date with the latest technology... your work is very impressive, especially from someone of your age. Its kind of funny, but I started out repairing consumer electronics when the TV's ran on vacuum tubes. I own a 3D printer, CAD software and lots of test equipment. I wish I had been born during this time period of 3D printing and the Internet as my inventive life would have been much easier and faster. Good luck to you and stay creative and up to date. ;)

Dude this deserves way more attention, amazing work! This is sick!!

[TomWilbourn]

I really would LOVE to see a step by step tutorial on just the fusion design aspect of this. Would be very cool to be able to follow along and build one myself. Great video!

Even though the master/slave control concept has been around for some time, the uniqueness of this robotic arm is the impressive compact and aesthetically pleasing design, demonstrating the advantages of 3D printing technology. Great job!

Using a scale model as a controller is such a genius but simple idea. Well done all around.

I am an engineering student who just bought a 3d printer. I was looking for a first project and i stumbled across this video. The idea for the controller is absolutely genius in my opinion. Other videos i have looked into felt so unapproachable with the amount of coding (also not my strong suit) but seeing how you dealt with that inspired me and i am going to attempt to build this myself. I also personally think that your arm moves much more organically compared to the others. keep it up! subscribed

I was wondering why the arm felt so human in the beginning so when you revealed that the controller was a scaled down version that you adjust by hand my mind was blown and it all made sense. Such a fun and cool idea

Dude, I just finished building your robot for our school project. We had some difficult times with the driver-board(that is because there are lots of boards using different parts such as (FET, capacitor etc.) customized by some companies for low budget costs with large income.We bought these boards and we had been troubled for weeks.After we got the right board, everything is doing welll with your explanation in the video. Thanks a lot for this amazing content❤ Keep doing your stuffs Sir!

Really cool. It would be a great addition to this robot adding a button that when pressed saves the current positoin of the motors (potmeters) and you can manually save multiple positions to replay them as a programmed animation. I did this with a hobby robot I built a few years ago

This is the best parking design for a robot I have ever seen.

I love the approach you took to controlling the arm, I have always loved that design of having a mini version of it that you move to control the big version. When I first saw how some commercial submarines have a mini arm that you move to move the big arm i new I wanted to build something like that!

[BasementCreationsChannel]

Great stuff! Controlling the arm with a miniature version that has potentiometers in joints is actually quite ingenious. I am planning to incorporate something similar in my own arm for the ease of training it.

[Jacob-fxou]

i have been building an Arduino robotic arm for a school project and this video has helped a lot, keep up the fantastic work

[kameld]

One of the sleakest robot arms I have ever seen, well done!

[cavstlt]

You will go a long way, a great future! And I need to also praise your parents for being supportive and surely encouraging you with your passion. Kudo to everyone. Good luck.

[xdanano]

Potentiometer control is genius. I might build this one looks fun

[JustinRobinson-km]

If you every get a chance it would be very helpful for you to add a document with a wiring diagram, that way we can roughly follow along. Thank you for sharing this with everyone, im going to take a shot at putting it together!

[micklethenickel]

This is the coolest manual control method that I've seen for a robot arm, great job!

[sunilkumar-lont]

Great job. Request for the 3d print files. Thanks

[CARLOSEDUARDO-bjvg]

Congratulations! I downloaded your project to try to replicate it here in Brazil. I haven't printed it yet because of the wrist gear. This is the biggest difficulty.
