Company

Run like a real firm.

51 students, a C-suite, seven crews with a lead each, and a purchase-request process that goes through design, operations and finance before anything gets ordered.

2026 leadership

What we learned

Communication, creativity, autonomy.

From our 2026 company evaluation: with over fifty people involved, structure came first. Then the Chief Design Officer ran idea-generation workshops, which produced the harpoon manipulators. As the year went on, leads handed more ownership to individual members, and the chassis came together from many people's work: thruster shrouds, camera mounts, manipulators.

Crew

Float Chassis & Buoyancy

ADAM's body and its buoyancy engine: a pump moves water in and out of a bladder, so the float sinks and rises with no thrusters.
