At four feet 3 inches tall and 66 pounds, Diego-san isn’t a perfect physical analog for a toddler (miniaturizing all of the parts would have driven Diego-san’s price tag way up), but his 44 pneumatic joints and the 27 moving parts in his extremely life-like face make for a humanoid that can mimic human movements–at least those of a one-year-old–quite deftly. The high definition cameras in his eyes take in the world around him–gestures, movements, facial expressions–and the team is developing algorithms that allow Diego-san to “learn” from these cues the same way a human baby would (to the extent that developmental psychologists understand this process, anyhow). The video below is the first of Diego-san that’s been publicly released, depicting the robot moving through a variety of facial expressions that it has learned from the humans it interacts with. Fair warning: Diego-san flirts dangerously with the uncanny valley phenomenon, as his facial expressions are just life-like enough to be somewhat creepy. But the ability to build a humanoid robot with this kind of human-like sophistication–particularly where the face is concerned–is fairly amazing. Diego-san’s research goals go both ways. for the roboticists and computer scientists on the project, Diego-San is granting a deeper understanding of sensory motor intelligence from a computational vantage point. From the other side, by mimicking the development of human babies Diego-san is helping developmental psychologists understand this phase of human development during which children first learn to interact with their physical environment and the other humans that populate it.
