World’s Smallest Robot Arm?? (3D Printed/Arduino)

I made an Arduino based robotic arm that's less than 2 inches (5 cm) tall for under $50! But is it the smallest?? This video will take you through the design, assembly, and code process. My goal was to make this arm as small as possible while still being able to be printed on a standard 3D Printer. I think this arm turned out pretty well!

If you haven’t exploded a Fusion model with joints then you haven’t used Fusion. Good work!

[@chinarsoft]

The master that I follow and wait with interest and curiosity...

[@Zhinoi]

I hope this blows up because this was done very well. Awesome work man

[@buildsomestuff]

Thanks!

[@TGStudios07]

Wow that is insane, I’ve built multiple robot arms and had problems with the motor weight limits, the joints on this one are fantastic

[@marcmaurette162]

Wow truly unique! Awesome job man! I'm jealous ngl

[@datatodatatodata]

Kiddo, that is AWESOME! It is also the perfect project for a kid I am mentoring, I was originally looking at designing my own, but I am pretty busy and it's been about a decade since I last did anything with electronics. lol
Anyway, I just wanted to let you know that you might be helping me help some kid get into STEM. Keep up the great work man!

[@Creative_Electronics]

That looks very good and it even works perfect!
Nice project! :)

[@mouminalsharef1095]

Keep doing a great job

[@kadingamerxd7468]

Awesome 👏

[@kevinkipkorir3132]

Awesome🎉

[@OOPS_CREATIONS]

Cool!

[@RoccosStuff]

This is awesome. It's cool you could make something so small without a resin printer. Did you use a .4mm nozzle or go down to a .25mm for the 3d printed parts?

[@buildsomestuff]

Thanks! Everything’s printed with a 0.4mm nozzle!

[@garyandjanesisk9063]

A great to the point and interesting presentation. The lever mechanisms are really cool. It would be interesting to do a side by side demo sometime with your larger robotic arm.

[@buildsomestuff]

Thanks! I may incorporate a “record and play” feature into both arms and run them side by side sometime in the future. Or possibly get the inverse kinematics working with both!

[@MidnightMaker]

Dude, this is amazing! I'm building the previous robot with my son. Are you going after James Bruton? Cause this is some nest level stuff. Thanks! I'm hoping my son will go to MIT, so these kind of projects are literally priceless.

[@buildsomestuff]

Thanks! That’s awesome! Have fun building with him and let me know if you have any questions!

[@yunosciences441]

Nice

[@pieterpennings9371]

This is really cool! i first found your channel from the other robot arm on your desk. Can i ask if you have any resources where to learn how to make the fusion 360 model with working joints?

[@buildsomestuff]

Thanks! This video may be helpful for implementing simple joints into projects: th-cam.com/video/gGgmA1WZESs/w-d-xo.htmlsi=M_ka1GtGZI58389z Hope this helps!

[@ZeeOperator-fc1wl]

Do you have a link to the 3D servo models you used? They look great

[@buildsomestuff]

Ha! Thanks! Unfortunately, I had to design these myself. However, you may be able to find similar files online.

[@RapWritersTV]

How did you learn fusion 360? Just can not get my head around it!

[@danielmichalski94]

Challenge accepted :3

[@SystemsPlanet]

No kinematics 😢

[@buildsomestuff]

Yah, sorry! I haven’t experimented with inverse kinematics too much. Maybe if someone else decides to make this they’ll give it a shot!
