You know, for all the hubbub we've been hearing about le robots (the robots), you'd think we'd see them put to better uses than chasing our pets and killing people. Right? Right. Well, the best use we can think of is education, and that's exactly what they're doing at an elementary school in Daegu, South Korea. Developed by the Korea Institute of Science of Technology (KIST), EngKey is just under three-and-a-half feet high, features a video display for a face, and seems hell bent on taking all those "teach English in Korea" jobs away from shiftless American college grads looking to postpone responsibility for one or two more desperate years. There are currently twenty-nine such devices, which -- get this -- are actually operated remotely by teachers in the Philippines. Is this the end result of globalism? Not quite yet: for the time being, the robots are still too cumbersome to operate and expensive to justify putting into production. But who knows? Maybe someday, kids.

We are such suckers for a cute robot. Take Mahru, for instance -- every time it does a jig or grabs a slice of toast we are charmed just a little bit more. And while the thing is impressive, it might be the manner with which they program the device that might be the most interesting part. Apparently, the gang at KIST have a system in place whereby an operator can wear a motion capture suit and send movements to the robot in real-time (well, mostly real-time -- there is still quite a bit of lag below the waist, so to speak). The video below shows said operator waving his arms and moving his torso, only to have the robot mirror his every move. Wild, huh? And if that ain't enough, the thing has learned a dance or two since we last laid eyes on it. Talk about giving Asimo a run for his money! Peep for yourself after the break.

We'd had some indication that robot teachers could be headed to classrooms sooner or later, but it looks like things may now be progressing faster than anyone thought. According to South Korea's etnews, the country has announced plans to invest in a so-called "R-Learning" program that promises to put robotic teaching assistants in up to 400 pre-schools by 2012, and expand to a full 8,000 pre-schools and kindergartens the following year. Those apparently wouldn't be in charge of the class (yet), but they would be used to do things like recite stories, and could let parents check in on the classroom and send messages to their children. If that trial program proves to be successful, the robots could then be expanded to elementary schools, and the Korea Institute of Science & Technology (the folks responsible for the bots) is apparently already eyeing international possibilities.
