So what if some mechanical cheetah can hop curbs in stride? The ATRIAS bipedal robot from Oregon State University can now step over obstacles without even looking. For this experiment, the ATRIAS was not outfitted with an imaging or navigation system and could only react to obstacles once it ran into them. As you can see in the video below, a 15-cm step is no match for this robo-ostrich. Even when planting its foot awkwardly or catching a toe, the ATRIAS soldiers on. It's only a matter of time until climbing stairs is just a walk in the park for the high-stepping automaton.
