  • Watch the first steps of a robot inspired by stick bugs

    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.

    We've seen some rather nightmare-inducing robots inspired by insects, but, once again, the folks at Germany's Bielefeld University have managed to turn something inherently creepy into a rather lighthearted affair. HECTOR, or hexapod cognitive autonomously operating robot, was designed to help its creators understand how exactly real animals manage to move so gracefully. Physically speaking, HECTOR sports six legs, with 18 joints in total, that protrude from an exoskeleton made of carbon fiber reinforced plastic. Its legs are given a rather life-like range of motion provided by a special set of "elastic joint drives" and a series of "biologically inspired" algorithms, and its exoskeleton can carry a load weighing 30 kilograms -- the robot itself weighs a mere 12 kilograms. What's more, HECTOR's built to learn from its experiences. Okay, so a three foot robotic insect that can carry nearly three times its weight does sound kind of creepy in retrospect, but HECTOR really does have some smooth moves. You can see at least one of its legs in action after the break.

  • Flobi robot head realistic enough to convey emotions, not realistic enough to give children nightmares (hopefully)

    We've seen our fair share of robots meant to convey emotions, and they somehow never fail to creep us out on some level. At least Flobi, the handiwork of engineers at Bielefeld University in Germany, eschews "realism" for cartoon cuteness. But don't let it fool you, this is a complicated device: about the size of a human head, it features a number of actuators, microscopes, gyroscopes, and cameras, and has the ability to exhibit a wide range of facial expressions by moving its eyes, eyebrows and mouth. The thing can even blush via its cheek-mounted LEDs, and it can either take on the appearance of a male or female with swappable hair and facial features. And the cartoonish quality of the visage is deliberate. According to a paper submitted by the group to the ICRA 2010 conference, the head is "far enough from realistic not to trigger unwanted reactions, but close enough that we can take advantage of familiarity with human faces." Works for us! Video after the break. [Thanks, Simon]

  • Artificial bee eye gives diminutive robotic air drones wider range of vision

    We'd bother telling you up front that it also gives them a new sense of purpose, but you're already versed in how the impending Robot Apocalypse is going to go down. Wolfgang Stürzl and his best buds over at Bielefeld University in Germany have just published a report detailing how an artificial bee eye could improve the vision of miniature robots -- ones that fly, in particular. By using a catadioptric imaging system, which captures an image using both mirrors and lenses, they were able to utilize a single camera to capture a full 280-degrees of vision, and a lowly internal computer is able to stitch the two panes together in order to create a usable image that humans can interpret. The idea here is to provide more sight with less space, bringing us one step closer to actually having our very own 'fly-on-the-wall' moment. Comforting, no?
