Robotic Bugs coax the real things

Here's a first: Bug-size robots have been used to coax cockroaches into unnatural acts. Research reported recently in the journal Science described how a team of European scientists placed tiny robots in a colony of laboratory cockroaches. Using behavioral modification methods, the whirring, partly-disguised faux insects were able to induce the real creepy-crawlies to follow their lead in seeking shelter in bright spaces. Bent behavior, indeed, for critters famous for lurking in dark, moist cracks. No one cares too much if cockroaches can be hoodwinked into acting against their own interests. Still, it's surprising that robots can insinuate themselves into colonies of living things, however wee-witted, and more or less take charge. Although not designed to address major philosophical issues, the research nonetheless points to how robot science appears headed in weird and unpredictable directions. Some scientists say it is inevitable that advances will ultimately affect the fundamental relationship between humanity and its machines. And many analysts say it is high time that societies start seriously considering the ethical dimensions of the technological advances, although others contend the dangers are exaggerated.
