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.

One of the long term plans for the FX1 is to have it carry its power source and be able to climb stairs with its human occupant.

It seems like it could be a pretty empowering technology for the disabled. Heck, I'd feel pretty empowered driving it... especially if it could be painted yellow and equipped with some big fork lift arms, suitable for fighting aliens.
