Not much info on the actual robot... For instance, I wonder how it has enough battery to follow a whale for 'months'? Which seems really unrealistic, as sperm whales can dive more than a kilometre, can't imagine an autonomous robot can support this kind of pressure, let alone for months at a time?
bigbadfeline21 minutes ago The bot doesn't have to dive deep, it can track, follow and listen to the whales from above using the same sonar gear. Also, I kind of doubt the whales would talk much when in the deep.
