Researchers at a U.S. university have unveiled a robot that can predict the actions of humans - and knows when to pour its owner a beer. Scientists at Cornell University equipped the robot with a camera and a database of 3D videos outlining basic human activities to teach it appropriate responses to various actions. The robot's prediction accuracy is at 82 percent, researchers claim, and it can also learn from mistakes. A video released by university researchers shows the Kodiak the robot opening a fridge door, and pouring a beer without being prompted. Powered by 16 laptop batteries, the robot can also make breakfast, put food in the fridge and even tidy up, according to researchers.
