Robot dog set to join US army troops
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!
