Sure… this is cool and all, but is it just me or do the springs in these robots make them sound like people having sex on an old mattress?

These robotic heads come from the Korea Institute of Science and Technology’s Center for Intelligent Robotics, where they were created to entertain the elderly through song. The performance gets more complex—and more bizarre—as the song goes on, and the bots are surprisingly good at conveying that certain feeling of despair. (Enjoy, elderly!) By far the hardest thing to understand, though, is why four heads would stop at the exact moment when everybody head-bangs to “Bohemian Rhapsody.” Talk about a missed opportunity.
