The Kyoto University in Japan has a nice line-up of robots in their Robo Garage Department.

One of them is the Chroino humanoid robot, which has a outer covering that serves also as a frame. The “monocoque frame” is made of carbon and plastic.
Using a technology named SHIN-Walk, Chroino has the ability to walk more naturally than traditional robots that walk stiffly with constantly bent knees.
The Chroino robot measures 35cm and weighs about 1kg. Videos of the Robot and more information available on the Robo Garage site.
