Demonstrator for Controls through Web-based Application and Drawing Robot

This is a Streamlit app that provides a library of number theory patterns that can be sent to a Raspberry Pi robot to print out. The patterns are based on various number theory concepts and can be customized with different parameters to create unique designs.

How it Works

The app is built using the Streamlit Python library and communicates with the Raspberry Pi robot via a Bluetooth using the socket library. Users can select from a variety of pre-defined number theory patterns or create their own by adjusting parameters.

Once a pattern is selected, the app sends an array of points to the Raspberry Pi robot, which uses a movement algorithm to follow the desired path, accelerating and deccelerating when necessary. The user can then watch as the pattern is drawn in real time.

How to Run the App

To run the app, you'll need to follow these steps:

1. Clone this repository to your local machine.
2. Install the required Python packages by running pip install -r requirements.txt.
3. Run the app using the command streamlit run Test.py or python -m streamlit run Test.py.
4. Connect your Raspberry Pi to your computer via Bluetooth.
5. Open the Backend/SendData.py file and change line 19/20 to the MAC address of your Raspberry Pi.
6. Open your web browser and navigate to http://localhost:8501 to view the app.
7. On your Raspberry Pi, uncomment and run the RPI/Movement.py file.
8. Once you have chosen a pattern, press the print button to send the data to the robot.
9. Click the button on the robot to start the print!

Note: You can adjust the size of the print by scaling the points in the Transform function in Backend/SendData.py

Note: You may need to adjust the port argument in the bot.motorRun(port, speed) call in the set_wheel_speed function in RPI/Movement.py based on which port each motor is plugged into. Use the follow graphic as a reference:
