RDnathKolkata/Percepta-Lucis ? reverse-engineered prompt

Build me a working prototype for a smart assistive headwear system for visually impaired users. It should use ESP32 based devices, an ESP32 CAM for vision, ultrasonic and flight time sensors for obstacle detection, vibration motors for nearby objects, Bluetooth audio alerts, and fall detection with emergency response. I want the camera side to run YOLOv11 based object recognition and send useful detections to a laptop or phone side component, then turn that into simple spoken or audio feedback and distance warnings in real time.

Please make the code clean and easy to flash, with separate sketches for the different ESP32 parts, plus any supporting app or server code needed to tie everything together. If you need current library docs or setup details, look them up online. Focus on something that feels like a real demoable assistive device, with clear sensor handling, smooth alerts, and sensible defaults that would actually help someone navigate safely.
