The so-called Scarlet Knight robot has this week completed a 225-day journey from the shores of New Jersey to the sandy beaches of Baiona in Spain -- fittingly the same port Christopher Columbus returned to after his first visit to the Americas -- aided only by a battery, ocean currents and its innate intelligence. Built by Rutgers University, the youthful robotic trailblazer performed a number of data gathering tasks as it went along, furnishing climate change researchers with more info on temperature levels, water salination and currents within the Atlantic Ocean. Now that it has been handed back to the US, the machine will be put up on display in the Smithsonian, so if you want a peek at the future of globetrotting that'll be the place to go.
