The material itself I find promising, but why not just use that with existing boats? The robot component is not justified. Also, given the size of the bot, 20 times its weight in oil means returning to base every hour or so. I see no reason to limit collection to such small amounts at a time. I'm glad you agree with me that the one month claim is bogus.
I didn't realize that you were talking about using it with existing boats; doing that instead of robots is pretty obviously a better solution, assuming that the material can be produced in large enough quantities, which may or may not be the case.
