Automatic NERF Sentry Gun

… A proper sentry gun, like one you’d see in a video game or movie, which can automatically track you then start shooting until you die (of amazement).

It was built by Instructables user BrittLiv, and comprises a NERF Vulcan gun, a stand, a motor and a laptop. Using recognition software, the laptop’s camera can track someone walking in front of it, the gun moving to follow the person’s movements.

While it can be fired manually, … it can also be programmed to shoot automatically at targets (and even programmed to not fire at certain people).

In summary, this is an autonomous motion-detecting, belt-fed NERF machine gun.
