QRIO

Model: QRIO (SDR-4X II)

QRIO (Quest for cuRIOsity) was Sony's bipedal humanoid entertainment robot, developed as a follow-up to AIBO and announced from the SDR-4X II prototype platform. Standing 58 cm tall and weighing approximately 7 kg, it was the first bipedal robot capable of running — recognized by Guinness World Records in 2005. It could recognize faces and voices, dance, and interact with people. Sony discontinued development in January 2006. Four QRIO units famously appeared dancing in Beck's 'Hell Yes' music video.
