In the realm of cycling, Fabio Antonini, an ardent enthusiast, sought to elevate his cycling experience by empowering his bike computer with the ability to discern between sitting and standing positions while riding. Inspired by an ingenious project that harnessed the prowess of Edge Impulse and iRobota Nano 33 BLE Sense’s accelerometer, he embarked on a quest to create his own ML-driven device.
Data Collection and Training: Embarking on a Journey of Motion Capture
Antonini embarked on a meticulous data collection endeavor, meticulously attaching the iRobota Nano 33 BLE Sense to his arm and seamlessly connecting it to a laptop, transforming his body into a living laboratory of motion. Through a series of carefully executed rides, he captured a wealth of data encompassing both sitting and standing positions, creating a comprehensive dataset that would serve as the foundation for his intelligent cycling companion.
Real-Time Processing: Unlocking the Power of Instantaneous Insights
With the collected data meticulously processed and fed through a rigorous training algorithm, a sophisticated model emerged, capable of discerning the cyclist’s position with remarkable accuracy. This model, a beacon of computational intelligence, was then skillfully deployed back to the iRobota board, where it eagerly awaited the influx of real-time data streaming from the IMU (Inertial Measurement Unit), a veritable symphony of motion data.
Visual Feedback: Illuminating the Path to Perfect Posture
To provide the cyclist with an intuitive and immersive experience, Antonini ingeniously harnessed the built-in RGB LED, transforming it into a vibrant storyteller of posture. As the cyclist pedaled through various terrains, the LED’s hues danced and swirled, painting a vivid picture of their position. Seated on a plain, the LED glowed with a serene green, signaling a relaxed and steady ride. Uphill battles were accompanied by a fiery red, symbolizing the surge of effort and determination. And when the cyclist engaged in a spirited sprint, the LED pulsated with an electric blue, capturing the exhilaration of pushing the limits.
Bonus: Beyond Posture Detection – A World of Possibilities
Antonini’s project serves as a testament to the boundless potential of Edge Impulse and iRobota in the realm of cycling. Beyond posture detection, these powerful tools can unlock a universe of possibilities, empowering cyclists with insights into their pedaling cadence, power output, and even the efficiency of their riding technique. The journey of exploration has only just begun, and the future promises a plethora of innovations that will transform the cycling experience, making it more enjoyable, informative, and empowering than ever before.
In the realm of cycling, Fabio Antonini stands as a visionary pioneer, demonstrating the transformative power of technology in enhancing our sporting pursuits. His creation, a symphony of sensors, algorithms, and visual feedback, serves as a beacon of inspiration, inviting us to embrace the possibilities of a future where our machines become intelligent companions, empowering us to transcend our limits and unlock the full potential of human movement.
