TRIMODAL-X — Extreme Variant¶
The research and exploration variant. Built to go where humans cannot. Volcanic vents, ocean trenches, disaster zones, contaminated environments.
Design Philosophy¶
TRIMODAL-X is not built to survive adverse conditions. It is built to operate in them — collecting data, deploying instruments, extracting samples, making decisions — for a full week without resupply.
Survival is the floor. Mission completion is the ceiling.
