Hi guys,

This is a 3 axis robot arm built with arduino uno card, i found nothing that i can use as an arm so i used plastic rulers assembled with glue. I haven't enough pins in the arduino card so i put a DC motor in the grabber.

Step 1: What You Will Need

  1. 4 rulers.
  2. 2 stepper motors.
  3. A DC motor.
  4. Arduino Uno card.
  5. Plastic curved base.
  6. Cables.
  7. Hot glue.
  8. Breadboard.
  9. 6x switches.
  10. 6x 10n capacitors.
  11. 6x 10k resistors.
  12. 2x 6v relays.
  13. 2x ULN2003 IC
