Human-carrying (or human-assisting) robots come in all shapes and sizes, but we haven't seen anything quite like this so-called Land Crawler exTreme bot. Weighing in at just 27 pounds, the robot can apparently carry a person weighing up to 175 pounds (providing they have good balance), or it can simply amble around on its twelve legs all by itself. Practical? Maybe not. But it is quite a sight to behold -- see for yourself after the break.
