1) Changing Blade Rotation Speed Using a Variable
Using a Remote Control
When the remote’s button 5 is pressed, let’s rotate the left and right blades simultaneously at a speed of 10.
Since the left blade is connected to port M3 and the right blade is connected to port M4, set the speeds of ‘M3’ and ‘M4’ to ‘10’.
Creating and Using the ‘Speed’ Variable
Create a variable named ‘speed’ and set its initial value to 10. When the remote button is pressed, the blades should rotate according to the value of the ‘speed’ variable.
To negate or remove the negative sign, use the multiplication (*) block and multiply by -1.
Adjusting the Blade Rotation Speed with the Remote

Speed Adjustment
If you want the system to respond to a single button press, set one of the buttons in the “Bluetooth 2 Buttons” block to ‘0’.

4. Troubleshooting Robot Issues
1) When the Power Does Not Turn On
  • Ensure the batteries are inserted with the correct polarity, matching the ‘+’ and ‘-‘ signs.
  • Inspect the battery pack cable for any breaks or disconnections.
  • Ensure that the battery pack cables are securely connected to the 6V, 12V power connector on the CPU board.
2) When the Remote Control is Not Working
3) When the DC Motor Does Not Rotate / Rotates in the Wrong Direction
  • Ensure that the motor cables are correctly connected to the motor port.
  • Check the motor cables for any signs of disconnection or damage.
  • Confirm that the motor cables are inserted vertically into the motor ports on the CPU board. If connected horizontally, the motor may not rotate.
  • Ensure the black wire of the motor cable is aligned with the arrow on the CPU board case. If connected in reverse, the DC motor will rotate in the opposite direction.
  • If the DC motor driver board is not inserted according to the assembly diagram, do not turn on the power. Insert it correctly as per the assembly diagram to avoid overheating risks during operation.
  • If the DC motor driver board is not inserted, place it properly and then turn on the power to check the operation.
4) When the Servo Motor is Not Functioning Properly
  • Ensure that the 3-PIN cable is connected to the correct OUT port.
  • Verify that the black wire of the servo motor cable is plugged in the direction of the arrow on the CPU board case.
  • Connect the cable so that the black wire aligns with the arrow on the CPU board.
  • Ensure that the direction of the servo motor label in the assembled robot matches the assembly diagram. If the label is oriented incorrectly, the servo motor may operate in reverse, or the angle may be incorrect, posing a risk of gear damage.
5) When the LED is Not Functioning Properly
  • Ensure that the 3-PIN cable is connected to the correct OUT port.
  • Verify that the black wire of the 3-PIN cable is plugged into the side of the LED pin with the white line.
  • Confirm that the black wire of the 3-PIN cable is connected in the direction of the arrow on the CPU board case.
6) When the Robot Operates Abnormally
  • Ensure that the direction of the DC motor shaft in the assembled robot matches the assembly diagram. Incorrect assembly of the motor shaft may cause the robot wheels to get stuck on the frame and malfunction.
  • Check that the cables are not caught in the drivetrain. If the cables are entangled with the drivetrain, the robot may not function properly.
  • Ensure that the assembly was done correctly according to the assembly instructions. If the assembly is incorrect, the robot may not function properly.
