Columbia's new silicone robot face learns to lip-sync from YouTube
Columbia Engineering researchers just built a flexible silicone robot face powered by 26 tiny motors that learned to lip-sync by watching YouTube videos instead of following rigid rules. After practicing its own facial mechanics in a mirror, its vision-to-action model beat five existing systems across 11 languages. Why it matters: Paired with ChatGPT, it could finally cure the stiff, uncanny lip-syncing that has plagued humanoids for years.
