A daily descent into underwater robotics. Each day: one true story, one engineering idea, one instrument you run yourself, and one dive into the wreck globe.
Five days on the hardest workplace on Earth — and why we build machines to go there for us.
01 MondayThe last unexplored place → 02 TuesdayBorn of emergencies → 03 WednesdayFinding a needle in a black ocean → 04 ThursdayWhen you must send the machine → 05 FridayThe ocean, unmanned →Week 1 asked why we go down. The University deep-session that follows this week asks it with a pencil in hand: a design brief for a vessel that must work at 1,000 metres in the open ocean — hull, power, comms, and what it would take to survey one wreck from this globe, end to end. The free week continues Monday: Week 2, "How Machines Swim."
Buoyancy, pressure, thrust and control — the four things every underwater vehicle has to get right before it can do anything useful at all.
01 MondayWhy things float, and why they roll over → 02 TuesdayThe sea gets heavier as you sink → 03 WednesdaySeven men and a crank → 04 ThursdayThe Secret in the torpedo → 05 FridaySwim like an animal →Week 2 gave you the four things a vehicle has to get right before it can do anything else. This weekend's deep-session puts all four into one design. Open the Builder, load the jellyfish archetype, and read its truth panel: net buoyancy, the B-to-G gap, the beat rate against the bell's natural frequency, thrust and watts. Then change one thing (a heavier battery, a stiffer ring, a deeper rating) and explain, in a paragraph, every number that moved. Week 3 starts Monday: "Seeing with Sound."
