The objective of the design report was to document the progress and detailed planning for the development of a motion-tracking insole. This report aimed to present the system architecture, data collection methodology, and validation strategy.
Tasks Completed:
- System Architecture Design:
Created a comprehensive architecture diagram detailing the insole’s key components, including the IMU (Accelerometer + Gyroscope), Pressure Pad, BLE module, and rechargeable LIPO battery. Specified the data flow between these components, with an emphasis on integrating data collection and real-time transmission using the ESP32. - Data Collection and Processing Methodology:
Documented the methodology for data collection, including the specific configurations for the Bosch IMU. This section also included steps for data preprocessing, error correction, and signal filtering to minimize sensor drift and saturation using MATLAB simulations. - Hardware Integration and Prototyping:
Outlined the hardware integration process and included initial tests conducted using an Arduino prototype. Summarized findings from these tests to support the decision to transition to ESP32 for final implementation. - Validation and Testing Approach:
Described the validation strategy, which includes bench tests for individual components and integrated tests to assess the system’s overall performance. Focused on planned methods to evaluate accuracy, response time, and battery efficiency. - Challenges and Risk Assessment:
Highlighted technical challenges faced during prototyping, including sensor noise issues and BLE connectivity stability. Conducted a risk assessment to identify potential project bottlenecks and proposed contingency plans. - Formatting and Presentation:
Structured the report to ensure it meets professional standards, with sections including an executive summary, system specifications, diagrams, and tables for data presentation.
