Python code ties OpenCV HOG+SVM person detection to two $18 Logitech webcams and an ORB + BFMatcher stereo pipeline to compute disparity and pick the closest target; an Arduino + servo drives a mounted Nerf gun. Demo works live but has false positives, frame‑rate vs accuracy tradeoffs, a narrow 53° camera FOV, shaky mounts that caused crashes, and torque issues requiring bearings and counterweights. Project succeeds as a proof‑of‑concept with reliability limits on commodity hardware.
