BigDog is a quadruped robot created by Boston Dynamics, designed with the intention of serving soldiers as an all-terrain pack mule. Using four legs for movement, BigDog is capable of automatically stabilising itself even after stumbling or navigating steep, rough terrain. The motors that power BigDog get a bit loud, so there's little chance of it being used during missions requiring stealth. It's hard to deny just how impressive the robot is though, and how unnervingly organic BigDog looks when stabilising itself. https://www.youtube.com/watch?v=cNZPRsrwumQ What's the craziest military weapon you know of?
