3. Coding Examples
- To check the answer, swipe the image to the side.
1) Controlling the Steering Mechanism
Using a Remote Control
- Button 7: Turn the tank to face left (servo motor angle 125)
- Button 8: Turn the tank to face right (servo motor angle 65)
- When buttons 7 and 8 are released: Turn the tank to face forward (servo motor angle 95)
Since the servo motor acting as the steering mechanism is connected to OUT1, set the servo value of ‘OUT1’ appropriately.
2) Changing Robot Speed Using a Variable
Using a Remote Control
- button 1: Move Forward
- button 2: Move Backward
- When button 1-2 are released: Stop
Since the left wheels and legs are connected to M1 and M3, and the right wheels and legs are connected to M2 and M4, set the speeds of ‘M1~4’ appropriately.
Creating and Using a Variable
Create a variable named ‘speed’ and set its initial value to 10. When holding down the remote buttons, the wheels should move according to the ‘speed’ variable.
- button 1: Move Forward
- button 2: Move Backward
- When button 1-2 are released: Stop
To negate or remove the negative sign, use the multiplication (*) block and multiply by -1.
Using a Remote Control
Wheels
- button 1: Move Forward
- button 2: Move Backward
- When button 1-2 are released: Stop
Speed Adjustment
- Button 5: Increase the 'speed' variable by 1
- Button 6: Decrease the 'speed' variable by 1
To increase or decrease the variable value, use the “Change Variable” block. Specifically, enter ‘1’ to increase and ‘-1’ to decrease the value.
Limiting Value of a Variable
Wheels
- button 1: Move Forward
- button 2: Move Backward
- When button 1-2 are released: Stop
Speed Adjustment
- Button 5: Increase 'speed' by 1 if it's less than 20
- Button 6: Decrease 'speed' by 1 if it's greater than 0
3) Controlling the Robot with the Remote
Limiting Value of a Variable
Wheels
- button 1: Move Forward
- button 2: Move Backward
- When button 1-2 are released: Stop
Speed Adjustment
- Button 5: Increase 'speed' by 1 if it's less than 20
- Button 6: Decrease 'speed' by 1 if it's greater than 0
Steering Mechanism
- Button 7: Turn the tank to face left (servo motor angle 125)
- Button 8: Turn the tank to face right (servo motor angle 65)
- When buttons 7 and 8 are released: Turn the tank to face forward (servo motor angle 95)
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.
