Nonstop Robot

In some of the scariest science fiction scenarios, evil robots refuse to die, no matter how fiercely people fight back. Now, science fiction has edged into science fact. For the first time, researchers have created a robotic machine that can take a beating and keep on trucking. Developed by scientists from Cornell University and the University of Vermont, the new robot looks like a spider with four legs. Until now, even the most advanced robot was almost certain to break down when damaged. That's because its internal computer simply doesn't know how to operate the machine after its shape has changed. To get around this problem, the spidery robot's developers equipped their invention with eight motors and two sensors that read how the machine is tilting. The motors and sensors all provide electrical signals to the machine's software. Using this information, the system follows a new procedure to figure out the machine's shape at any given moment. The program chooses from among 100,000 possible arrangements of parts. From there, the computer considers a wide variety of possible next steps, and it calculates how best to move the robot forward the longest possible distance, before trying to move again. The new strategy is a major advance in robotics, scientists say, and it's far from scary. The technology may someday help researchers create better artificial limbs that give new freedom to people who lack arms and legs. The new knowledge might also help scientists understand how people and animals figure out their own sense of place in space. "Designing robots that can adapt to changing environments and can compensate for damage has been a difficult problem," says neuroscientist Olaf Sporns of Indiana University in Bloomington. "This work provides a new way toward solving this important problem."—E. Sohn
