Robots show their personalities at Consumer Electronics Show

LAS VEGAS – Professor Einstein can roll his eyes, stick out his tongue and give a simple explanation of the theory of relativity. With his lifelike rubbery "skin" and bushy mustache, he can almost make you forget he is a robot. The Einstein robot is among dozens roaming the Consumer Electronics Show in Las Vegas that can be your companion or educator or baby-sit your children. Japan's SoftBank Robotics meanwhile announced a partnership that will allow its humanoid robot Pepper to travel onboard state-owned SNCF trains in France to assist travelers. While robots have been around for years, advances in technology and artificial intelligence have allowed developers to give them traits that enable the devices to be seen as members of the family.
