Kinetic study of a bipedal humanoid robot and mode of the spherical inverted pendulum
Abstract: Studies on an anthropomorphic biped walking robot have led to the expectation that a bipedal humanoid robot will actively participate in human living environments. The authors created the human-size 35 active DOF bipedal humanoid robot "WABIAN" and the human-size 41 active DOF bipedal humanoid robot "WABIAN-R" as the initial step in creating a bipedal humanoid robot. The authors also put forth a fundamental method of controlling whole-body cooperative dynamic biped …

Electroluminescence
Abstract: Electroluminescence (EL) is a kind of luminescence which is an optical and electrical phenomenon in which light is emitted by certain materials due to the passage of an electric current or a strong electric field. The mechanism behind electroluminescence is the radiative recombination, or spontaneous emission. The electrons get excited and release their energy as photons. The holes and electrons before recombining are separated either by doping the given material …
