Robot dog joins the US army

Meet Alpha, the robotic dog designed to be a soldier's new best friend.

He's been developed to go out with American troops into dangerous situations - and is controlled by a touchscreen computer.

The robo-pup can stand upright and walk for 20 miles without a break!

Alpha has been made by Darpa - the same team who developed Cheetah, the super-fast robot who can run 100 metres even quicker than Usain Bolt!
