Microscopic robots walk autonomously using simple 'brains'

It's long been possible to make extremely small robots, but they usually need some form of direct external control just to operate. Cornell scientists may have solved that problem on a basic level, however. They've created microrobots (no more than 250 micrometers across) with basic electronic "brains" that let them walk autonomously. Two- and six-legged robots move relatively simply, while a four-legged "dogbot" changes speed when an operator sends laser pulses.The trick was to build a complementary metal-oxide-semiconductor (or CMOS, as computer enthusiasts know
