Robots are taking over many tasks for us. They are especially useful in war zones and for armed forces in general. Take these Unmanned K-MAX Robocopters: having returned from a nearly 3-year deployment, they have helped reduce the number of convoys on the ground and delivered more than 4.5m pounds of supplies. These robocopters are reliable and require low maintenance. They can lift a ton of weight in a safe fashion. Pretty impressive, aren’t they?
