Exobots are the way to explore the universe

Autonomous, self-replicating robots — exobots — are the way to explore the universe, find and identify extraterrestrial life and perhaps clean up space debris in the process, according to a Penn State engineer, who notes that the search for extraterrestrial intelligence — SETI — is in its 50th year.

“The basic premise is that human space exploration must be highly efficient, cost effective, and autonomous as placing humans beyond low Earth orbit is fraught with political economic, and technical difficulties,” John D. Mathews, professor of electrical engineering, reported in the current issue of the Journal of the British Interplanetary Society.
