This is probably the strangest robot vehicle I have seen, and as expected it comes from Asia more exactly - Tokyo. It's a robot with 4 legs and a spot for one (small) person inside, it can move easily on the street but I doubt the same "easiness" happens when going up/down the stairs.

It resembles the popular cartoon Buzz but it is obvious that there some differences, like the legs being shorter, having no arms, etc.

Along with the BoingBoing post about this robot vehicle, there is also a "testimonial" of the person who took the photo:

The machine containing this man was fully mobile and powerful enough to get up and down the curbs with ease, not to mention immaculately put together. He rolled right past me in front of the station toward the park, accross the bridge of freaks and over to the crosswalk bridge stairs. Then he waited patiently for a break in traffic and took off down the street away from the crowds. He never once cracked a smile, stopped only when the crowd was too thick to let him by, and seemed at best to not notice all the people staring and trying to talk to him
