Microrobots Walk Autonomously

Cornell researchers installed electronic “brains” on tiny solar-powered robots, so they were able to walk autonomously sans external control.

“Before, we literally had to manipulate these ‘strings’ in order to get any kind of response from the robot,” said Itai Cohen , professor of physics in the College of Arts and Sciences. “But now that we have these brains on board, it’s like taking the strings off the marionette. It’s like when Pinocchio gains consciousness.”
