They grow up so fast, don't they? It was just a few years ago that HECTOR the stick bug robot was little more than a twinkle in Bielefeld University's eye, and it's already taking its first steps. Okay, so this isn't quite a tear-jerking moment, but it's still an important achievement in robotics. As you'll see in the video below, all of HECTOR's six insect-like legs move independently while reacting to unexpected changes in terrain. They shift to maintain balance on slippery ground, and raise themselves above small obstacles the moment they sense resistance.
