Amphibious drone/ US

Establishing a beachhead on enemy-held turf is historically one of the most dangerous jobs in warfare, just ask Achilles. But the robotic age may make it slightly less so. A research team from Stamford, Conn. has developed an amphibious drone that they are currently testing with the Marines. The GuardBot is a robot ball that swims over water at about 4 miles per hour and then rolls along the beach, at as much as a 30-degree incline and 20 miles per hour.

It uses a nine-axis stabilization system, “pendulum motion” propulsion system, which moves the bot forward by shifting the center of gravity back and forth and a variety of steering algorithms.
