DARPA, the people who brought us The Internet(tm), have another project in the works. Pet-Proto is a robot designed to maneuver around obstacles and make autonomous decisions. Eventually, robots like Pet Proto will be sent to places humans cannot tread. Or maybe will be employed as very athletic butlers. One thing is for sure: They definitely won't come to your house and murder you in the middle of the night... Because robots are our friends... right?
