You can download two arduino code files.

[File]

1. Arduino Robot arm code ① - robot_arm_init.ino

Before operating the robot arm, We need to initialize the angles of the servo motors.

• Angle of the bottom servo motor = 90˚
• Angle of arm1 servo motor = 90˚
• Angle of arm2 servo motor = 90˚
• Angle of grip servo motor = 0˚
  
  

After detaching the servo motors, upload the initialization source code to Arduino.

Once the upload is complete, reassemble the servo motors.

2. Arduino Robot arm code ② - robot_arm_control.ino

Let's use two joysticks to create a code that moves the robot arm.
