Researchers create robo-moth, dream of a cyborg cricket-filled future
Researchers have long turned to insects for a little inspiration when creating robots, but things have entered a terrifying new dimension this week, with two separate groups each finding new ways to meld bug and machine. The further along of the pair is a group of scientists from Tokyo University's Research Center for Advanced Science and Technology, who have not only used a live silkmoth to control a toy car, but severed the head of a moth and wired it into the vehicle pictured above (look closely). By directing stimuli to the moth's still-functioning antennae, the researchers were able to record the motor commands issued by the brain's nerve cells and, in turn, control the vehicle -- which, in addition to totally freaking people out, allows them to study and record data on how neurons respond to stimulus. Slightly less far along on the road to bug armageddon is Pentagon contractor OpCoast, which is working on some full on "cyborg crickets" that behave like the real thing but have the added benefit of being able to form a mobile communications network in an emergency situation. That network, the company says, could eventually consist of hundreds or thousands of the crickets which, like real crickets, would communicate with each other through wing beats, and even be able to vary their "call tone" when they detect the presence of chemical or biological agents, or potentially even the scent of a person trapped in rubble.Read - AFP, "Japanese scientists aim to create robot-insects"Read - PhysOrg, "Cyborg Crickets Could Form Mobile Communications Network, Save Human Lives"[Via reddit]
Robo-moth can't flap, still likes flames
We're no strangers to the use and abuse of insects in the name of science, but we've gotta say that this robo-moth mech is the best example yet. Built by a few mad scientists over at the University of Arizona, robo-moth intercepts signals sent by the moth's eyes to its teensy brain and turns them into movement. The bot can detect where the moth is looking, and turns in that direction. Since moths have quite the fancy pair of preceptors and built-in reflexes, it's going to allow for some pretty complicated actions once scientists figure out how to control more motion than left and right. Researchers are looking down the road to where a moth could act as a disposable bomb-sniffing robot, or where paralyzed humans could more accurately control wheelchairs with their thoughts, but that's all still a ways out.
