Instructables user “BrittLiv” took a Nerf N-Strike Vulcan and transformed it into an autonomous sentry gun. This video game-like weapon is powered by an Arduino Uno controller with a few servos to help the unit move from side to side. It automatically locks and fires at targets, but can also be manually fired by using a controller. To help keep intruders out, the gun’s firing speed has been increased by 50%, an programmed to not fire at users wearing the Instructables robot logo on their shirt. “My main aim was for it to look awesome; which was difficult to achieve without removing the front part of the gun.
