Arduino Grab

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

For this project you will need:

Tip: You can use any Arduino board!

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

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.

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