University of California have made it possible for their robot–an Einstein lookalike–to teach itself to make realistic facial expressions.

The team has been upgrading their Einstein-robot since many years, and in the past had to manually program the robot’s 31 servo-driven facial "muscles" for it to form the right expressions.

Now the Einstein robot has learned to guide itself. To quote the team's release

So far, Einstein has managed to learn to convey emotions like sadness, anger, joy, and surprise. It's only a matter of time before it can stick out its tongue.
