Video: GM's robots send holiday greetings

Fifty years ago, General Motors was at the fore of early robotics development and deployment, collaborating in 1961 with Joseph Engelberger, the so-called father of robotics. That partnership resulted in the first industrial robot used in a GM production facility.

Today, GM employs 25,000 of them.

And boy have robots grown up! Here's a holiday greeting from a few of them, in GM's Fort Wayne factory, programmed to do something other than welding, fastening and painting.
