We've enjoyed watching KIST's Hubo do crazy things like wear the face of Albert Einstein and ride a Segway, but we haven't given as much attention to its brother Mahru. Feeling left out, the biped learned to dance with its upper body whilst walking around -- an impressive feat, considering it wasn't all that long ago that scientists first managed to get these things to take five steps without falling flat on their faces. Mahru also releases scents to express its artificial emotions, so you should be able to smell something fishy when it achieves sentience and begins angrily plotting to destroy its creators. Take a gander at a South Korean TV news report after the break.
