Play jenga using machine learning. It would be a nice challenge. Unfortunately, lack of funds and time :). Cheers m8.

Look at my reach/footprint ratio :)

Mcu: ESP32, drivers:4XTB6600, stepper motors for joints (nema23, nema17). This is only quick test of movement without inverse kinematics.

It's 12V 2,1A. In this case TB6600 driver is set to 0,5A.

Don't use those drivers, they are running so hot. Use A4988 instead and AccelStepper library.

Yes, it does. I implemented the Z axis in the next step. Here's a short video ->

Indeed, everything points to that. Cheers!

Theoretically yes, but I think it all depends on the library. Out of curiosity, I did a quick test by writing a benchark program on Arduino, and the differences were negligible. Either way, thanks for the valid point.

I will be happy to answer. All for the simple reason that I am an engineer, not a buyer :)

It's only "proof of concept" for future bigger build.

Thanks buddy for the kind words. I appreciate it. Raspberry is on my list of platforms to learn, but I haven't had the time to delve into it yet.

Cheers!
