| # Title Exercise Repetition Counter Using Discrete Clip On Device Team Members: - Prithvi Patel (prithvi7) - Arhan Goyal (arhang2) - Vikrant Banerjee (vikrant3) # Problem Maintaining proper workout form and accurately tracking repetitions during exercises can be challenging, especially for individuals working out at home or without a trainer. Existing solutions either rely on expensive gym equipment or smartphone applications, which lack precision and real-time feedback. There is a need for a cost-effective, standalone device that can accurately count repetitions and display them in real-time without setting up a camera in the middle of gym (all existing solutions for the problem). # Solution We propose a wearable, discrete clip-on device with a custom PCB that uses an MPU6050 accelerometer and gyroscope to detect arm motion during exercises. The system will process motion data to identify and count repetitions, displaying the count on an 8-segment display in real-time. Additionally, the device will include a timer to measure the duration of each repetition and provide feedback through a vibration motor when the user completes a repetition. The time per repetition and set completion criteria can be adjusted using a simple dial or potentiometer. # Solution Components ## Subsystem 1: Motion Detection and Processing - **Function**: Captures arm motion using a 6-axis motion sensor and processes the data to detect exercise repetitions. - **Components**: - MPU6050 (6-axis accelerometer and gyroscope) - Microcontroller for data processing and communication ## Subsystem 2: Timer and Feedback Mechanism - **Function**: Measures the duration of each repetition and provides feedback through vibration. - **Components**: - Timer functionality implemented in software - Vibration motor (e.g., 310-101) for feedback - Dial or potentiometer for adjusting time settings (e.g., 10K potentiometer) ## Subsystem 3: Custom PCB - **Function**: Provides a compact and efficient platform for integrating the motion sensor, microcontroller, power supply, and display connections. - **Components**: - PCB with integrated traces for components (sensors can be directly connected/soldered onto the PCB without additional breadboards or jumper cables) - Voltage regulator (e.g., LM7805) for stable power supply - Power source (rechargeable battery) ## Subsystem 4: Display and Feedback - **Function**: Displays the real-time repetition count to the user. - **Components**: - 8-segment display - Driver IC (e.g., MAX7219) for efficient control of the display ## Subsystem 5: Power Management - **Function**: Ensures the device operates efficiently and reliably over extended periods. - **Components**: - Battery charging circuit (e.g., TP4056) - On/off switch for user control # Criterion For Success 1. The system accurately detects and counts exercise repetitions with a minimum accuracy of 90%. 2. The 8-segment display updates the repetition count in real-time without noticeable lag. 3. The timer accurately measures and tracks the duration of each repetition and signals set completion through vibration feedback. 4. The time for repetitions and sets can be easily adjusted using the dial or potentiometer. With this design, we aim to provide a practical, affordable, and user-friendly solution for fitness enthusiasts to track their workout reps effectively. |
