2. Code Upload & Robot Operation
Without Direct Coding, when using the Complete Robot Operation Program provided by XROBO
When Directly Coding individual robot operation programs
1) When using the Complete Robot Operation Program
- If the X4 Operation Program is already uploaded, to the robot, please proceed directly to Operate Robot.
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 Download and Load the Operation Program
- Please refer to the Using the Operation Program page to download the X4 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 1 times to select the "Do" 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) Rotating the Propeller
Setting Propeller Rotation Speed
Let’s set the rotation speed of the propeller to 10.
Since the DC motor with the propeller is connected to the M3 port, set the speed of ‘M3′ to ’10’.
Using Remote Control
While holding the 5th button on the remote control, the propeller should rotate at a speed of 10. When the button is released, the rotation should stop.
To ensure the propeller stops when the button is released, place the stopping code in the ‘else’ section of the ‘if-else’ block.
2) Changing Propeller Speed Using Variables
Creating a variable
Create a variable named ‘Speed’ and set its initial value to 10.
Set the initial value directly below the ‘Start’ block using the ‘Set Variable’ block.
Using a variable
Let’s make the Cyclone rotate according to the ‘Speed’ variable when the 5th button on the remote control is pressed.
Instead of entering a number directly, insert the ‘Speed’ variable block.
Using Remote Control
- button 5: Rotate the propeller
- When button 5 is released: Stop
- button 7: Change propeller speed to 10
- Button 8: Change propeller speed to 20
To change the variable value, use the ‘Set Variable’ block.
3) Controlling the Cyclone with the Remote Control
Using 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
Since the DC motors with wheels are connected to the M1 and M2 ports, adjust the speed of ‘M1’ and ‘M2’ accordingly.
Using 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
Propeller
- button 5: Rotate the propeller
- When button 5 is released: Stop
Speed Adjustment
- button 7: Change propeller speed to 10
- Button 8: Change propeller speed to 20
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.
