A waddle of Emperor penguins surprised researchers in Antarctica today when they commandeered "Yeti," an autonomous robot designed to detect crevasses and deploy scientific equipment on the ice.
Laura Ray, professor of engineering at Dartmouth and principal investigator of the Yeti project, reports that her team worked out a deal with the penguins: “You let us get on with our research, and we'll give you a ride whenever we can.”
