Gloucester: Ryan Santos, an O'Maley Middle School student, tests his remote-operated vehicle, or ROV, a submersible, that he built at Maritime Gloucester on Thursday afternoon. He is among 40 students who are taking part in the two-week long Summer Engineering Adventure, which is a partnership of Maritime Gloucester, MIT's Edgerton Center, the Gloucester Education Foundation and O'Maley Middle School. The students rotate between projects in Gloucester at Maritime Gloucester and on the Cambridge campus.
