Check out these funny lookin’ Humanoid Robot Platforms from Hubo Lab at Kaist(Korean Advanced Institute of Science & Technology, kinda like MIT of Korea).
HUBO-FX1 is the human-riding robot having 12 DOF. The development concept is that the robot can walk naturally with carrying a person or a load of 100kg, so the lower body takes after legs of human and the upper body takes after a chair. A person who sits on the upper body can control the robot naturally using the built-on joystick installed. It has many kinds of sensors. Each ankle has the 3-axis force/torque sensor which measures a normal force and 2 moments. Each foot has the inclination sensor which measures angle of the slope. Also the rate gyro and the inclination sensor of the body can do a stabilization of itself.
