Photographed at a baptismal font in the chapel of Schloss Burlinghoven, a nineteenth-century castle on the campus of the German National Center for Information Technology, the walking robot Sir Arthur stands with its creator, research scientist Frank Kirchner. Sir Arthur began as a relatively simple robot with sonarlike "vision" that prevented it from trapping itself in corners and snagging itself on obstacles. It was successful enough that Kirchner obtained funding from the U.S. Defense Advanced Research Projects Agency to assemble a team of researchers from diverse disciplines: computer science, math, physics, and electronic and mechanical engineering, to build an enhanced, solar-powered version that can cross rough outdoor terrain.
