"A timid-looking four-legged robot about the size of a Chihuahua might seem like an unlikely companion for soldiers of the future.
Yet the robot, called LittleDog, could ultimately help researchers create more sophisticated robotic assistants for military personnel, including automated "pack-mules" capable of hauling heavy loads over tough terrain.
This is because LittleDog is remarkably agile for a robot when faced with treacherous, uneven terrain. Researchers are also fine-tuning its movement to be even faster and more animal-like over rough terrain.
LittleDog was created for the US Defence Advanced Research Projects Agency (DARPA) by US robotics company Boston Dynamics."
