Pool tests

On Thursday, the team from Cornell University conducted five pool tests of its Proteus vehicle at the Spawar site. "The marker dropper, treasure grabber, and vision system are performing beyond our expectations," the team says on its blog.

That marked an improvement from some bumpy test experiences a day earlier at the hotel pool. But the sub's crew was able to work things out, according to the team blog: "The vehicle's central computer, Eddy, is ready to direct further vehicle testing. There were tense moments at the pool last night when Eddy's memory got wet, but after drying out for several hours, Eddy is working again."
