- Please refer to the Using the Operation Program page to download the X3 Operation Program and load it into mBlock.
③ Uploading the Code
- Upload the code to the robot by following the instructions on the upload method page or video (starting at 34 seconds).
④ Operating the Robot
- ① Turn on the power to the CPU board.
- ② Press and hold the START button for more than 2 seconds. Release it when you hear the "Do Re Mi Fa Sol La Ti Do" melody.
- ③ Press the START button 9 times to select the "High Re" tone.
- ④ Turn on the power to the remote control and have fun controlling the robot.
2) If You Are Coding the Program Yourself
① Preparing for Upload
- Ensure mBlock is installed on your computer. If not, please install mBlock.
- To operate the robot, you will need a download board and a download cable. If you do not have these components, please purchase them.
② Coding the Program
- Launch mBlock and freely code your program by referring to the coding examples or the manual.
③ Uploading the Code
- Upload the code to the robot by following the instructions on the upload method page or video (starting at 34 seconds).
④ Operating the Robot
- ① Turn on the power to the CPU board.
- ② Briefly press the START button on the CPU board and then release it.
- ③ Turn on the power to the remote control and have fun controlling the robot.
3. Coding Examples
- To check the answer, swipe the image to the side.
1) Moving the Wheels with the Remote Control
Move Forward/Backward
- Button 1: Move forward
- Button 2: Move backward
- When Buttons 1-2 are released: Stop
Since DC motor 1 attached to the left wheel is connected to the M1 port and DC motor 2 attached to the right wheel is connected to the M2 port, set the speeds of the M1 and M2 ports appropriately.
Turn Left/Right in Place
- Button 3: Turn Left in Place
- Button 4: Turn Right in Place
- When Buttons 3-4 are released: Stop
Remote Control
- Button 1: Move forward
- Button 2: Move backward
- Button 3: Turn left in place
- Button 4: Turn right in place
- When Buttons 1-4 are released: Stop
2) Moving the Bomber’s Propellers with the Remote Control
Move Both Propellers Together
Let’s set the speed of the DC motors attached to the left and right propellers to 10.
Since DC motor 3 attached to the left propeller is connected to the M3 port and DC motor 4 attached to the right propeller is connected to the M4 port, set the speed of the M3 and M4 ports to ’10’.
Move the Left Propeller Only
Let’s set the speed of the DC motor attached to the left propeller to 10.
Since DC motor 3 attached to the left propeller is connected to the M3 port, set the speed of the M3 port to ’10’.
Move the Right Propeller Only
Let’s set the speed of the DC motor attached to the right propeller to 10.
Since DC motor 4 attached to the left propeller is connected to the M4 port, set the speed of the M4 port to ’10’.
Remote Control
- Button 5: Move both propellers together
- Button 7: Move the left propeller only
- Button 8: Move the right propeller only
- When Buttons 5, 7, 8 are released: Stop
3) Controlling the Bomber with the Remote Control
Remote Control
Wheels
- Button 1: Move forward
- Button 2: Move backward
- Button 3: Turn left in place
- Button 4: Turn right in place
- When Buttons 1-4 are released: Stop
Propellers
- Button 5: Move both propellers together
- Button 7: Move the left propeller only
- Button 8: Move the right propeller only
- When Buttons 5, 7, 8 are released: Stop
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 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.
5) 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.
