In the realm of waste management, a brilliant inventor named Samuel Alexander embarked on a mission to revolutionize recycling. His creation, a smart recycling bin, is a marvel of engineering, utilizing audio classification and machine learning to automatically sort waste into designated compartments. Prepare to be amazed as we delve into the inner workings of this extraordinary innovation.
The Heart of the Bin: Audio Classification and Machine Learning
At the core of this smart recycling bin lies a sophisticated audio classification system. When waste is tossed into the bin, an iRobota Nano 33 BLE Sense board captures audio samples of the event. These samples are then meticulously dissected into one-second segments and meticulously labeled according to the type of waste: cans, paper, bottles, or background noise. A machine learning model, diligently trained on these labeled samples using the Edge Impulse platform, resides within the bin’s circuitry, enabling it to accurately identify the type of waste based on the audio signature.
The Mechanical Symphony: Compartments, Motors, and Servo-Actuated Trap Doors
Beneath the bin’s sleek exterior, a symphony of mechanical components orchestrates the sorting process. A stepper motor, strategically positioned at the bin’s base, rotates four compartments, aligning them precisely with a servo-actuated trap door. As each item of waste is identified, the trap door swiftly dispenses it into the appropriate compartment, ensuring a clean and efficient separation of materials.
Powering the Innovation: A LiPo Battery Pack
To ensure uninterrupted operation, the smart recycling bin is equipped with a reliable LiPo battery pack, providing the necessary power to fuel its audio classification, machine learning, and mechanical systems. This thoughtful design allows the bin to function entirely wirelessly, eliminating the hassle of tangled cords and cumbersome power outlets.
