ROBOTICS | Miniature 3-axis Robotic Arm

Millions of years of evolution have created the most universal and perfected instrument – the human arm. Everything in our modern world exists thanks to this instrument. Even to this day, the industry has not found a more versatile tool to manipulate objects in 3D space than the robotic arm, which is essentially a mechatronic copy of a biological arm. The versatility of the robotic arm is truly unique. Combined with advanced machine vision and various end effectors, it can be used for almost anything. Today, the rapid development and miniaturization of mechatronic systems allow expanding the scope of use even further. In particular, until recently the size of the robotic arms was limited by the size of motors, gearboxes, and controllers. And now we see great momentum toward micro-automation with the use of miniature highly precise robotic arms. Most importantly, the cost of these robots approaches the cost of similar Cartesian systems. Thus, they can be effectively used in micromanipulation and micro-assembly processes for various domains.

In this video, you can see a short demonstration of a miniature 3-axis robotic arm using ultra-precise Harmonic Drive gearheads, high-performance brushless motors, high-resolution absolute encoders, and integrated controllers.

I like how you put your hand in frame to deal with all the constant CGI comments lol.

[Tech_Planet]

Awesome, I always like your showcases!

[VK-qhpr]

Not sure if I missed it. Do you have a list of used parts ? Opensource repi ?

[ekaggrat]

what motors are these? really compact .

[Osamoele]

Hey, great work. Just a little question : how did you achieve backdriveability with harmonic gearboxes ?

[abhishekmanjarekar]

Can you mention the link of those Motors used in video? Or any equivalent specifications motor will also do....

[zyromskij]

I'd love to use those motors and gearboxes in a gimbal project - can You share the product name/number or at least manufacturer?

[PetroRomani]

the movement is in sync with the music, genius

[otownhogan]

This is the best 3 axis robot I've ever seen!

[mokscorderotv]

speed of arm moving is excellent parts are excellent how much power it consume. in my opinion you can actually use that to build a suit like iron man legs and arms suit like a starship trooper suit speed is important and accuracy of movement for building a power suit and we just need to solved how much power it consumes and the weight of that arm.

@OleksandrStepanenko thank you for the awesome work :D, could you please provide the stepper model

[saurabhverma]

Hi…can you share all parts details for assemble the same arm…and navigate to make this one similar

[ht_ml]

блин вот если бы все авторы на ютубе были такими же перфекционистами

[jakobhalskov]

These demos blows my mind, and I always need to remind myself this is not CG :D

[israelsoto]

Nice work, where I can find this kind of motor with harmónic drives

[nadahere]

Oleksandr, you should see the kinematics in our FrictionLess Gear and Rotary Universal Device [pump/engine/etc.] mechanism. They can also be formulated as linear actuators.

A miniature replica of energy vault would look mind blowing

[kevino]

What a great drilling and tapping machine this would make. Can this be used with arduino uno? TIA

[sathyakumarn]

Hi! Have you commercialised these yet? And are the designs opensource?

[NoName-xvnn]

Lighting so good you know it’s NOT cgi
