RoboArm Control Hub - Arduino & Flask Web Interface

A modern web-based control system for a 4-DOF robotic arm using Arduino and Flask. This project provides an intuitive GUI interface to control a KUKA-style robotic arm with precision and ease.

🤖 Features

• Real-time servo control through web interface
• 4 degrees of freedom (DOF) control
• Intuitive slider-based interface
• Cross-platform compatibility

Hardware Requirements

• Arduino board (Uno recommended)
• 4 servo motors
• KUKA-style robotic arm frame
• USB cable

Software Requirements

• Python 3.11.4 or higher
• Arduino IDE 2.0+
• Modern web browser
• Operating System: macOS (M1), Windows, or Linux

🛠️ Installation

1. Clone the repository

   git clone https://github.com/agneya-1402/RoboArm.git
   cd RoboArm

2. Install Python dependencies

   pip install -r requirements.txt

3. Upload Arduino Code

   • Open arduino/arm_1.ino in Arduino IDE
   • Select your board and port
   • Upload the code

4. Configure Serial Port

   • For M1 MacBook:
     • Check port name in Arduino IDE (usually /dev/cu.usbmodem1101)
     • Update app.py with correct port name

🚀 Usage

1. Start the Flask server

   python app.py

2. Access the control interface

   • Open your web browser
   • Navigate to http://127.0.0.1:5000

3. Control the robotic arm

   • Use sliders to control each servo:
     • Servo 1: Base rotation (0-180°)
     • Servo 2: Arm segment 1 (0-180°)
     • Servo 3: Arm segment 2 (0-180°)
     • Servo 4: Claw control (0-180°)

🔌 Pin Configuration

Servo	Arduino Pin	Function
Servo 1	8	Base rotation
Servo 2	9	Arm 1 movement
Servo 3	10	Arm 2 movement
Servo 4	11	Claw control

🤝 Contributing

1. Fork the repository
2. Create your feature branch (git checkout -b feature/AmazingFeature)
3. Commit your changes (git commit -m 'Add some AmazingFeature')
4. Push to the branch (git push origin feature/AmazingFeature)
5. Open a Pull Request

⚠️ Safety Notes

• Always ensure the robotic arm has adequate clearance before operation
• Start with slow movements when testing new positions
• Keep fingers clear of the claw mechanism
• Ensure proper power supply to prevent servo jitter

🐛 Troubleshooting

1. Serial Port Connection Issues

   • Verify the correct port in Arduino IDE
   • Check USB connection
   • Ensure proper permissions on the serial port

2. Servo Movement Problems

   • Verify power supply adequacy
   • Check servo wire connections
   • Ensure servo positions are within limits
