Thank you, technology.
Guard dog getting slow? Try upgrading your home security with this nifty sentry Nerf gun. You’ll have trespassers scurrying away with soft ammo plummeting at their backsides.
Robbie Gleichman and Sadegh Asefi created the the Nerfinator, a robotic sentry, as their final project for an Introduction to Robotics class. The Nerfinator uses a Kinect RGBD camera to aim at faces and then releases its flurry of foamy projectiles.
You can also watch Gleichman’s YouTube playlist of all their videos.
