This looks cool, a walking robotic chair, the HUBO FX-1.
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.
