The military is investing in robots from hefty unmanned vehicles to tiny Throwbots to perform a wide variety of previously impossible missions. To a designer, creating these robots is not only an amazing engineering challenge, but also a way to help save lives in the battlefield.
Wartime robots date back to World War II and the Cold War (check out these mid-20th century robots: German Goliaths and Soviet teletanks). Today, the military invests millions of dollars into testing and deploying automated systems so that robotic warfare can deliver new capabilities to those fighters at the tip of the spear.
