Here is my comment, sorry for the time, this time the comment is about a interview to a participant of a ship tournament, but it wasn´t a simple tournament of ships that we know. This ships were robots that compete for a winner. The interviewed was talking about the funtions and how can the ships handle without getting lost oh the way. I think that this type of tournaments or contest are very interesting because his porpose is to demostrate, compare and see the best inventions, all with a good work of engineering, and I could say that is wonderful to see how the ship doesn´t descompose if it touches the water.
