Arduino Grab

Introduction: Arduino Grab

If you have a 3D printer then... you must try to build one of this robotic arm-grab toy!

Step 1: What You Will Need - Hardware

For this project you will need:

Tip: You can use any Arduino board!

Step 2: The Circuit

The connections are pretty easy, see the above image with the breadboard circuit schematic.

Servo Motors:

  • Servo for Grab movement to Arduino pin 6
  • Servo for Rotate movement to Arduino pin 5
  • Servo for Up/Down movement to Arduino pin 4
  • Servo for Forward/Backward movement to Arduino pin 3
  • All black cables to GNDAll red cables to Vcc - 5V

Potentiometers:

  • for Grab movement to Arduino pin A0
  • for Rotate movement to Arduino pin A1
  • for Up/Down movement to Arduino pin A2
  • for Forward/Backward movement to Arduino pin A3
  • All left pins to GND
  • All right pins to Vcc - 5V

Buttons:

  • Teach button to Arduino pin 7
  • Start button to Arduino pin 8

Buzzer:

  • buzzer to arduino pin 9

Step 3: 3D Files and Assembly of the Robotic Arm

Step 4: The Code

If you want to disable the home position of your arm, just comment out the lines with "goHome();" command.

Note: You will need to change the min/max values for every servos to meet your setup.

Step 5: Well Done!

Great news! You have successfully complete this guide and now you have your own 3D printed Arduino Robotic Arm!
