🤖 $8 Microcontroller Powers Real-Time AI Human Tracking A creator has built a real-time AI tracking system using an ESP32 microcontroller that costs just around $8. By running a person detection model directly on the chip, it can detect and track human movement without relying on the cloud. No internet connection, no server round trips, and no rented GPUs. Everything runs locally on the device, delivering near-instant response times. The creator says the next step is connecting the system to a robotic arm. Key highlights: • Runs entirely on an ESP32 microcontroller • On-device AI inference with virtually no network delay • Brings capabilities once limited to expensive hardware to a low-cost platform The real breakthrough isn't just the technology—it's the cost. When real-time AI tracking is possible on an $8 microcontroller, advanced robotics becomes accessible to students, hobbyists, and makers everywhere. #artificialintelligence #esp32 #robotics #embeddedai #innovation
