Video: Elektro the Robot

Technology has come a long way since the '30s, but in his day Elektro was the bees knees when it came to robots. Built by the Westinghouse Electric Corporation in its Mansfield facility between 1937 and 1938, Elektro the robot stood seven feet tall, weighed 265 pounds, and acted on voice commands. Today, he is said to be the oldest surviving American robot and makes his home at the Mansfield Memorial Museum. Here, Elektro shows off at the 1939 World's Fair.
