Hi All, This is an article from The Times (London UK) 10th May, concerning a robot sailing boat getting ready to cross the Atlantic. http://www.timesonline.co.uk/tol/news/uk/science/article3904557.ece
There are a few of these things around- they all talk about their extreme capabilties for research and collecting data, but none mention anything about collision avoidance??? Keep your eyes open ladies and gentlemen.
