The Eccerobot (Embodied Cognition in a Compliantly Engineered Robot) team brings the term "humanoid robot" to a whole new level, by installing their robots with a humanoid skeleton, joints and tendons and even senses so that they can better mimic human movement and interraction.

Instead of the usual metals and more rigid plastics, Eccerobot's skeleton is made from a springy, bone-like, thermoplastic polymer, supplemented with a kitline and elastic polymer for muscles and tendons. Take a look at how it works:-

I don't know about you, but I've got a bad feeling about robots which are too human-like. Let's just say that robots should remain as machines and once we cross that barrier, who knows what will happen.
