The ground had just failed. The robot went in first.
After a roof collapse in an operating iron-ore mine, the area had to be understood before production could resume. The usual way costs days and puts people under ground that has already proven it can fail.
What actually happened
A robot running Sarthi's mission stack entered the affected drift, mapped the rockfall zone in 3D, and captured the imagery the engineers needed to assess the failure, all before a single person stood under that roof.
The work was carried out as field research with the mine's cooperation, in a real post-event situation, not a staged demonstration. Detailed site imagery will be published here once the operator has cleared it.
What it proves
Post-event assessment is the sharpest version of the inspection problem: unknown damage, zero infrastructure, and enormous pressure to resume production. The mission worked there.
It is the direct ancestor of Sarthi's M3 post-event mission, and the reason we can offer it with a straight face: it has already been done where it mattered.
If your mine has an event response plan, we should talk about what a robot-first assessment would change in it.
