Build a Pan-Tilt Face Tracking Robot (Phase 1 MVP - Python & ESP32-CAM)

I want to build a highly minimalist, budget-friendly desktop robot that tracks a person's face in real time. This is Phase 1 of a larger project; the goal here is strictly to build the pan-tilt tracking base using low-cost components... (Budget: ₹1500 - ₹12500 INR, Jobs: Arduino, Computer Vision, Microcontroller, OpenCV, Python, Robotics, Video Streaming)
