Meet Mira, the adorable little mini-bot built by Pixar technical director Alonso Martinez. The little robot is like a giggling glowworm weeble!
According to Martinez, Mira uses face detection to detect when someone is looking at her, and to follow their gaze as they move about. She’ll get sad when you hide (note the color changing base), but when you reappear, she laughs.
Unfortunately, there’s no word on when Martinez might make his creation available to the rest of the world, but he does intend to develop her further to help enhance her simulated emotions and make her interactions with humans feel more genuine.
