Mimic VS BIPR

It might be possible but it may not be the best choice for a beginner project. By using efficient use of attach() and detach() calls I built and coded up a 4-servo robotic arm that runs on just two-18650's (Mimic), but again it's not something you should try as a first project unless you have a decent understanding of stuff like Kirchhoff's Law &c.

Several years ago I made an arduino based arm and I wanted to do exactly what you are talking about so I included the ability loadstore and reload the arm movements from EEPROM. The project and source code are here and you should be able to re-use the EEPROM storage and retrieval parts of the code (or more maybe).

That still very cool and I love the oragami idea! I've looked into oragami for sources of inspiration for different kinds of leverage although I can't say I completely understood the math. 🤪 That's too bad about your 3D printer. I made a simpler robot arm that used 4 servos and I used popsicle sticks to make mine heh.

I wrote exactly what you're describing for the Arduino *I think* and here's the sauce.

I wrote something like this a few years back. It is a robotic arm that let's you control it using an identically shaped arm that has potentiometers at each joint instead of servos. So one arm 'Mimics' the other. The code for reading, controlling, and recording the movements to EEPROM is there if you want to grab anything. Also, you mention needing to get your button code correct and that same project has an interesting button library I wrote that let's you multiplex one button into tons of different selections by letting you define any combo of (up to 3) short and long button presses and configuring what function to run for that "buton gesture". You might find that useful (or maybe confusing the code isn't ideal for learning from haha).
