Field notes
Momo is presented as a solo desk project rather than a production robot, with the maker describing months of work, failed leg prints, and two unusable Raspberry Pis. Its movement system uses diagonal leg pairs for a trot, and every servo's home angle was calibrated through a web panel. The page also lists roughly 90 minutes of runtime and 23 facial expressions, while noting that sound is off by default in the interactive demonstration.
