Share Bipedal robots (at least some of them) are becoming increasingly agile and humanlike in their movements. Despite this, one physical aspect remains stuck in the uncanny valley—realistic facial expressions. Robots still aren’t great at replicating complex and fluid face muscle interactions at speeds comparable to their biological inspirations. One solution, however, may be found by treating expressions as an interplay between various “waveforms.” The result is a new “dynamic arousal expression” system developed by researchers at Osaka University that allows a bot to mimic expressions more quickly and seamlessly…
