This here is a remote-controlled paintball robot. Well, it's more like a remote-controlled car with a paintball gun on top, but still. It is awesome.
Set up with stair-climbing wheels and a rotating top, this bad boy will instill terror into the hearts of anyone who enters your home. Want one? Currently, it's a project on funding website Kickstarter in search of money, so if you want one, pony up some dough so the mad scientist behind these things can get his workshop in order.
