Excellent! Love the learn and replay feature, very smart

[smiffysnail]

Love your work. have printed the parts and built it and it is all wired up ready to go.

Anyone using freecad and having issues with displacement when importing all the files at once? I am going through the whole process and trying to get the URDF file from the robot arm but the files combined together upon import do not look like expected robot arm

Thanks, looks awesome. I have a more background question, in order of one to be able to do this from scratch, what major/course you need to study? Thanks

[Roxomus]

I am thinking of a few things:
1) Use ESP Now and send signals between two ESP32s instead of arduino nanos. One would contain the 4 potentiometers while the other remotely controls the arms.
2) Create multiple save presets.
3) Use OpenCR to recognize and move according to one of the presets stored.

In terms of the already existing code that you've made, how would you rank the above 3 in the order of complexity?

this is amazing.. please try making one using esp32 and have it controlled by ps4 controller using bluepad. that one be intresting.

The when i save the code using nob its not working its just shaking and blow my servos 2times

Buen video, fan número uno de fabri creators

[josephsmith]

SUBSCRIBED PERIOD!!! I've been waiting a long time for someone to teach me how to do exactly this. 👍👍👍

[BrodeySheppard]

Would have been absolutely sick using 40 or 80kg servos and a motor at the base instead of a servo. But still pretty cool!

I am planning this as my first „real“ Arduino build, could you please tell me what kind of and how many screws I need? (And if I need something else that’s not on the list)
Thx a lot!

[nithinmathewjoji]

Thanks I was looking for such a video for a long time buddy thanks a lot

[StarrySnippets]

also can you make another version in which you can control the arm with a real arm movements please

[ipadize]

if this uses kinematics, its not gonna be trivial

[StarrySnippets]

can you modify it and control it with joysticks wireless

[pranayy_art]

Ooooo thank you I also written lots of code for this same project but it worked but didn't work as good as I expected where can I get the code

[markussi.]

Eine app steuerung für unterwegs wäre sehr gut

[insido]

Love the video Can you use an UNO R3 for this? instead of the custom board?

[philippmeurer]

At 6:10 where you tighten the screws, how does it still move when you tighten it? Are there bearings underneath?

[antob]

cant able to purchase the file.. any upi link to buy directly
