There was in fact a limit to how deep humans could go even in pressurized underwater vehicles.
As you might expect, the world of autonomous drones are performing tasks unheard of until just recently. The ASME video, “Plying the Depths,” shows some very interesting undersea autonomous vehicles and then the surface “Saildrones,” the subject of a previous DTC Blog story.
