AI-Powered Autonomous Security Turret
input a live camera feed → output a person detected, tracked and locked inside 2.5 m
A dual-controller turret built with a four-person final-year team: the Raspberry Pi 5 runs YOLOv11 and OpenCV person detection while an STM32 Nucleo handles microsecond-precision PID motor control — so vision never stalls the motors. 40–45 FPS on the edge, zero cloud.
- A low-latency UART protocol at 115,200 bps keeps the two controllers in lock-step.
- Layered safety: software geofencing, PID overshoot protection, a human kill-switch and automatic failsafe cut-off.
- TOF-sensor logic moves it between detect, track and engage within 2.5 m; a sub-1 kg, fully 3D-printed chassis, under ₹70,000 in hardware.
