Instruction:

• Ensure that the left motors (front and rear) are connected together to OUT3 and OUT4 on the motor driver.

• Ensure that the right motors (front and rear) are connected together to OUT1 and OUT2 on the motor driver.

• Connect the motor driver control pins to Arduino as follows:

  • IN1 → Pin 8

  • IN2 → Pin 9

  • IN3 → Pin 10

  • IN4 → Pin 11

• Connect the servo motors to Arduino pins:

  • Gripper Servo → Pin 2

  • Lift Servo → Pin 3

  • Rotate Servo → Pin 4

  
  

Note:

• The front and rear motors on each side must share the same output to move together.
