1. Robot Assembly
1) Assembling the Robot
- Please refer to the manual for assembling the robot.
- Ensure all components are properly connected.
2) Verifying Cable Connections
-
Propeller-connected Rotating DC Motor
→ Connect to the M1 port on the CPU board.
2. Code Upload & Robot Operation
1) If You Are Not Coding
- 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.
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
1) Spinning the Propeller
Counterclockwise Rotation
Let’s spin the propeller at a speed of 10 for 1 second.
Since the rotating DC motor with the propeller is connected to the M1 port, set the speed of ‘M1′ to ’10’.
Clockwise Rotation
Let’s spin the propeller at a speed of -10 for 1 second.
If the speed value is prefixed with a ‘-‘, the DC motor will rotate in the opposite direction.
2) Gradually Increasing Propeller Speed
Counterclockwise Rotation
Let’s rotate the propeller at a speed of 10 for 1 second, then at a speed of 15 for 1 second, and finally at a speed of 20 for 1 second.
Note that a time value of ‘1000’ is equivalent to 1 second.
Clockwise Rotation
Let’s rotate the propeller at a speed of -10 for 1 second, then at a speed of -15 for 1 second, and finally at a speed of -20 for 1 second.
3) Changing the Propeller’s Rotation Direction
Move in the Following Sequence
- Speed 10 for 1 second
- Speed -10 for 1 second
Move in the Following Sequence
- Speed 20 for 1 second
- Speed 10 for 1 second
- Speed 0 for 1 second
- Speed -10 for 1 second
- Speed -20 for 1 second
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.
- Verify that the jumper cap is properly inserted into the 12V power connector on the CPU board.
- If there is no jumper cap available, use a 3×8 bolt to connect to the 12V power connector as an alternative.
- Inspect the battery pack cable for any breaks or disconnections.
- Ensure that the battery pack cable is securely connected to the 6V power connector on the CPU board.
2) 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.
3) 프로펠러가 로봇에 걸려 잘 회전하지 않을 때
- Ensure that the motor shaft is assembled so that it is facing upward. If the motor shaft is facing downward, the propeller may catch on the DC motor and not rotate properly.
- Check that the cables are not caught in the drivetrain. If the cables are entangled with the drivetrain, the robot may not function properly.
