PWM issues connections

Hi people!!
Somebody can help to resolve a problem with my arduino one r3, I have the rover shield v1… Already upload the example code include on pdf instructions but still the motor or servo havnt any change.
Idk what else to do!

@Haru30 Welcome to the RobotShop Community. To confirm, you have a DFRobotShop Rover V2?

  1. Confirm that the gearbox was assembled correctly, the driving sprockets can rotate and the tracks are not under considerable tension
  2. Confirm the wires are connected between each motor and each terminal
  3. Confirm the On/Off switch is turned ON and there are batteries connected correctly
  4. Ensure the batteries are charged

If these don’t resolve the issue, please provide a few clear photos of your setup from the top, sides and bottom.
