After realizing that nobody had ever actually made a sentry gun like the ones in video games, the Andromeda Strain, Aliens, or Congo, Aaron Rasmussen created the world's first sentry gun with his younger brother Ezra Rasmussen. The project exploded across the internet, accumulating over 400,000 hits in 2.5 days, attracting investor inquiries, and bringing the US Army to Aaron's dorm room. He later started a robotics company with one of the investors who contacted him because of the project.
