Robot Arm - Alien3D UFO Feb 2023

This is the project for the Alien3d UFO box for February 2023

I have created code so it can work on both an Arduino Nano or an ESP32wroom.

This project is remixed/inspired by https://www.instructables.com/Automated-Robotic-Arm-That-Learns-Ft-Tinkercad-Ard/
While building the project you may want to check the instructions on the instrucables page to know how to set the servo arms in the correct place, and what lenght screw each is. In my assembly video it shows the range of travel the arms should have.

Printing:

Please print all the parts in the included 3MF (not the one called preview) or the STL files. All parts should be flat on the bed, or with its flat side on the bed (joystick controller body and lid)

Components:

• 1 Arduino microcontroller 
  • ESP32 or Nano (others might work but you will probably need to edit the code and wiring)
• 10x M3 nuts
• 9x M3*6mm screws
• 12x M3*8mm screws
• 3x M3*10mm screws
• 7x M3*12mm screws
• 4x M3*20mm screws
• 4 SG90 Servos
• External 5V power is you are using the Nano (the usb connection is not enough for the servos) If you are using the ESP32 the USB C connection is fine

Programming:

You will need to use the Arduino IDE to open and upload the code to your board. You can download it from:

https://www.arduino.cc/en/software

That website also has many references on how to get started with arduino 

ESP32:

If you would like to use the Arduino Cloud Editor and upload your code through there please visit:

https://create.arduino.cc/editor/dsk001785/2b754fdb-4ba3-426d-8cb2-cf54f6c367c3/preview

If you would like to do it locally on your pc, please use the robotArmESP32.ino to program your board.

You will need to import a library to make the code work. Please search for and install the ESP32Servo library by John K. Bennet in the library manager in the Arduino IDE or manually download it from below and install into your libraries folder.

If you would like to do it locally on your pc, please use the robotArmNano.ino to program your board.

You do not need to import any libraries.

Please make sure to select ATmega328P (old bootloader) for the processor when uploading the code.
