By now, you're no doubt well acquainted with the Albert Hubo
Einstein robot developed by the mad scientists at KAIST
, but some researchers at the University of California, San Diego has also been working on their own Einstein bot for the past little while, and they've now managed to teach it some new tricks. While the bot has previously been able to display a full range of expressions through some pre-programmed facial movements, it's now able to teach itself
how to smile or display other emotions thanks to a new trial-and-error technique dubbed "body babble." That apparently works by comparing Einstein's attempts at an expression with some facial recognition software, which provides Al with some positive feedback each time he manages an actual expression. Did we mention there's a video? Check it out after the break.
The folks at UC, San Diego have kindly pointed us towards a bit more background
on their Einstein robot, including a video
of its pre-self-teaching days, and a couple of behind-the-scenes pics
. Head on past the break for one we like to call "Einstein: Behind the Face."
