What could possibly go wrong?...
"But these robots are the size of a speck of dust. Thousands fit side-by-side on a single silicon wafer similar to those used for computer chips, and, like Frankenstein coming to life, they pull themselves free and start crawling.The Microbots Are on Their Way | NYT
“We can take your favorite piece of silicon electronics, put legs on it and then build a million of them,” said Dr. Miskin, a professor of electrical and systems engineering at the University of Pennsylvania. “That's the vision.”
He imagines a wealth of uses for these microbots, which are about the size of a cell. They could crawl into cellphone batteries and clean and rejuvenate them. They might be a boon to neural scientists, burrowing into the brain to measure nerve signals. Millions of them in a petri dish could be used to test ideas in networking and communications."
